There’s been a lot of talk lately about airlines around the world beginning to favor smaller aircraft. Not just amid the pandemic but for the foreseeable future as well. The debate was given fuel when Lufthansa’s CEO made comments about potential down-gauging of its fleet ahead. But have we really entered the era of smaller airplanes for good?
Many have argued that even when demand for air travel does return there will be less of it overall because of a precipitous and permanent drop in business travel. And beyond that, even where demand does exist, it will be for convenient, point-to-point service, not on A380s via big hubs – as smaller planes emerge that are capable of flying farther and people shy away from big, crowded airports and the hassle of connecting. All of which calls for smaller planes. I’ve argued recently that this seems a little hasty. Nevertheless, the jury is out, and as they say – only time will tell.
Have smaller planes taken over flying?
One thing we can look at is whether the notion that smaller planes rule the day holds true at major airlines right now. And pulling some Flightradar24 data we can see that this has been happening – mostly. The headline takeaway seems to be that bigger planes do still have their place, but for obvious reasons smaller wide-bodies have proven more desirable on many global routes during the past year.
Lufthansa dropped its Very Large Aircraft quickly
If we look at Lufthansa’s data, the trend is very clear right from the beginning of the pandemic. The A380 and the 747s (both -400 and -8I) took a definitive hit beginning in March 2020. That was it for the A380 and the 747-400 for good, it seems. The small rebound in A380 flights recorded in recent months were storage-related. And since the pandemic started, it’s clear that the smaller A330 has been clearly favored, taking up nearly double the percentage of flying it had at Lufthansa pre-pandemic.
What’s most interesting here is that the 747-8I did come back, in some weeks to pre-pandemic levels. That’s quite a big plane. It is probably hard to fill these days. But it is Lufthansa’s flagship now – it has a First Class cabin and it can carry quite a bit of cargo. As a result it kept flying for a while on the bigger US routes like LAX. However recent dips in demand, and the winter season, saw the smaller and more fuel-efficient A350 come in to replace it on many routes. As I write this the Lufthansa 747-8I is in flight on just two routes – Mexico City (MEX) and Buenos Aires (EZE) to Frankfurt (FRA).
If I were to take a guess, I’d say we continue to see the 747-8I for some time on these bigger routes and in busier seasons. It may turn out to be one of the last options for passengers to fly a 747 a few years from now. Eventually, though, the more efficient 777X will replace it. Though Lufthansa has said it’s looking to shift to smaller airplanes overall, the 777X seems a natural fit for its big hub to hub routes. I don’t think we’ll see a day when the A350 is the largest plane in Lufthansa’s fleet – at least as long as Germany remains Europe’s largest economy.
Delta favors smaller, but only by a little bit
If we look at Delta, which also has a wide range of wide-bodies in its fleet, the picture is a little more complicated. In part that’s because initially its 777s and A350s (both of which fit about 300 seats) took over quite a lot of flying while its smaller 767s (200 to 240 seats or so) were more or less parked.
Since then, however, the 777 fleet has been retired and the 767s (both -300 and -400 series) have been doing nearly 60% of Delta’s wide-body flying. And its smallest Airbus wide-body, the A330-200, has flown much less throughout the pandemic. The A330-300, A330-900neo and A350-900 have filled in the rest of the flying, but while they were doing a majority of the wide-body flying in the first months, they’re not back to flying roughly the same percentage of Delta’s wide-body flights as before the pandemic.
It’s interesting to note that a number of 767s have been retired during this time, and A330-300s have been used to fill the gaps where necessary despite having a higher seat count. If no 767s had been retired it’s likely the total percentage of flights run with the 767 would be even higher.
What’s the bottom line?
It seems that airlines have tended to park their biggest planes, but perhaps not as drastically as some might have expected. That may have had a lot to do with cargo capacity. But cargo capacity will continue to be a consideration post-pandemic as well, so it’s not as if these planes will prove useless once things get back to normal. And if we see the boom in travel demand that some are predicting is on the way, many of these larger aircraft may see they get plenty of use yet.
Will there be less very large aircraft in airline fleets overall? Yes, probably. The A380 is all but done for except at a handful of airlines. And will smaller, long-range planes like the 787 prove popular in the years ahead? No doubt. But the bigger, fuel efficient planes like the 777X and A350-1000 will almost certainly still have their place in the sky too.

The aviation industry has allowed people to connect the world in unimaginable ways. Due to this, it has contributed massively to social and economic development globally.
However, the aviation sector produces nearly 1.8% of annual carbon emissions. It is almost half of the total growth in carbon dioxide emissions in the last twenty years due to the expansion of flights, increasing routes, and airline sizes.
In the loop, the commercial aviation sector has also been affected by climate change. The change is due to increased noise levels, air pollution, and waste production.
According to the International Energy Agency (IEA), the industry recorded 2.8% of global CO2 emissions in 2019. But now, the industry has pledged to be carbon neutral by 2050 through a focus on a critical low-carbon strategy, says IATA. By looking at this futuristic development, airline businesses are becoming more and more optimistic.
The Action Plan
The aviation industry has taken steps to reduce rising carbon emissions. The industry had framed targets that included carbon-neutral growth before the pandemic. But the pandemic compelled the industry to make some critical decisions. One of them is to fasten the action plan for low-carbon development.
McKinsey recently studied the industry’s emissions. According to the report, the industry's aviation emissions would be reduced by 18 to 35 percent by 2030. However, as the aviation industry’s growth is recorded from Asia, including India, China, and Southeast Asia, decarbonization can only work if airlines from these nations actively participate in the development.
“For aviation, zero-carbon is a bold, audacious commitment. But it is also necessary.”
-IATA Director General Willie Walsh
Airlines and other businesses are under pressure to make rapid progress towards lower emissions. It is because breakthrough technology like hydrogen-powered planes has started manufacturing.
For example, British Airways, Delta Air Lines, Inc., and United Airlines Holding Inc. have already made net-zero commitments by introducing hydrogen-powered planes. Similarly, JetBlue Airways Corp has set a target of 2040 to introduce low-carbon planes in no time.
So, by looking at above comitments, how will aviation progress in terms of low-carbon development? What are those fundamental ways that’ll guide the industry to see a sustainable future in real life?
4 Ways Aviation will Look Forward to Reducing Carbon Emissions
Green Fuel
Aviation considers green fuel as one of the quickest paths to low carbon development. Green fuel can be a game-changer in lessening carbon emission impacts. But, furthermore, it can lead to drastic climate change. Green fuel, also known as sustainable aviation fuel (SAF), is made from renewable sources such as plants or waste.
As per IATA, SAF can cut carbon emissions by nearly 80%.
But specific concerns like cost and availability are equally essential to think about. For example, the United States and other countries consider subsidies to decrease prices and increase supplies. They are practicing this due to limited availability. Also, some airlines are blending small amounts into the fuel they buy for their aircraft.
Other concerns, such as planes running properly on pure SAF, are also highlighted. In addition, flight engines based on petroleum fuel rely on their oily qualities to lubricate parts and function appropriately. So, it's unclear if green fuels offer that amount of strength in their engines to fly a flight.
Despite so many heated concerns (that are valid), the industry still looks good as Boeing (BA.N) studies the above issue. It has even committed to ensuring its planes are certified for 100% SAF by 2030.

Lower Carbon Technologies
Technological improvements to lower carbon emissions include retrofitting existing aircraft, adopting the latest fuel-efficient aircraft, retiring old aircraft, and others.
Several ongoing electric or hybrid-electric aircraft technology projects are in the pipeline. They are being identified to enter the industry between 2022-2030. In contrast, some of them are already in service.
Developments in Infrastructure
The International Civil Aviation Organisation (ICAO) has created plans to reduce fuel burn and greenhouse gas emissions (GHGs). The plans have been forwarded to optimize communication, navigation, surveillance (CNS), and air transport management (ATM) regarding zero-carbon development.
Apart from this, airlines are also working to align emission cuts with investments. Consumption of fuel usually covers 20-30% of operational costs. It is one of the highest costs of an airline business. So now airlines are considering adopting fuel-efficient flying and airport operations.
Collaborations
Today, aviation needs more stakeholders for a sustainable future. They can only increase the efficiencies and development of SAF.
Stakeholders from technology providers, oil companies, and energy production could drive demand and help bridge the cost gap. For instance, airlines commit to buying SAF at a particular price or at a different price than traditional fuel jets. These factors could eliminate market risks for fuel suppliers.
Next, airlines can work with B2B customers willing to pay for the decarbonization initiative. For example, airlines could use loyalty-program rewards as incentives for every customer to choose airlines that use SAF. Collaborations like these can help the industry accelerate its low carbon emission initiatives.
These Top Airlines Commit to Using New Technologies
Aviation industry leaders aim for 30% of the aircraft to operate with the help of new technologies by 2030. They strongly support the introduction of hydrogen and electric-powered planes to the market in order to reduce the industry's carbon footprint.
So, let’s see the airlines and their commitment to creating a sustainable aviation future.
Air New Zealand
Air New Zealand’s initiatives such as True Target Zero accelerate the adoption of zero-emission aircraft worldwide. Air New Zealand is delighted to work with other industry leaders working towards net-zero goals.
“Air New Zealand pledges to put low carbon solutions in place for all our smaller domestic and regional flights in the future. However, we know that the drive to decarbonize the aviation industry is impossible for one airline to tackle alone. Rather it’s a joint venture, and it's all about joining hands together.”
-David Morgan, Chief Operational Integrity & Safety Officer, Air New Zealand
Mokulele Airlines and Southern Airways
Mokulele Airlines, the largest intra-state carrier in America, has already worked for many years as a maven to bring electrification to its air transportation system.
“We are satisfied to join the World Economic Forum in seeking a global public commitment to promoting sustainable air travel.”
-Stan Little, Chairman & CEO, Mokulele Airlines and Southern Airways
Braathens Regional Airlines
The airline has the ambition to make its flights fossil-free by 2030. The airline has included electric planes, and with its partnership with True Zero Aviation, it is taking steps to accelerate towards actual low carbon emissions.
Can Aviation Make a Difference in the New Path of Development?
There are a lot of positive aviation stories from all over the globe. However, aviation also has some barriers to the new path of low-carbon development. Nevertheless, aviation can undoubtedly make a difference by introducing technologies, implementing result-driven strategies, implementing the right tools, and many more.
But from the customers' perspective, choosing to fly less can be another good reason to reduce an individual’s carbon pollution. The reduction can be up to 50% each year. So even avoiding long-distance flight travel could make a significant difference to aviation.
Business travelers could adopt or choose to use virtual meeting technology. These could be other crucial factors limiting the carbon footprint in the atmosphere.
Whatever you choose to opt for, it is high time to contribute to a more sustainable aviation sector for the future.
Frequently Asked Questions
How can airlines reduce their carbon footprint?
Airlines can introduce more efficient aircraft. Efficiency in technological aspects, reduce flight delays, and increase the use of sustainable lower-carbon or alternative fuels. Also, investment plays a vital role here. They can invest in emissions initiatives and promote low-carbon travel.
How can an airline achieve its carbon-neutral goals?
An airline can explore hybrid and electric aircraft technology to reach carbon-neutral goals, reduce carbon emissions using SAF, and embrace fewer flight routes (distance).
Do aircraft harm the atmosphere?
Aircraft create very polluting elements and are highly challenging means of transport. Indeed, air traffic represents less than 2%-3% of the global CO2 emissions, yet it transmits direct CO2 emissions than cars on roads.

While countries continue to implement new Omicron-related restrictions in response to the rising number of cases globally, a majority of these are in the form of enhanced COVID testing requirements – not travel bans. As a result, travel demand for popular peak-season destinations has remained strong, and over the past few days we’ve seen a BIG INFLUX in bookings as news trickles out that Omicron may be a less severe variant.
If this continues, we expect to see another prolonged booking surge, so plan accordingly and get your requests in ASAP for best options – especially parking and hotels. While the new U.S. 24-hr testing requirement for return travel is tight, it’s not a big deal if you are prepared with an approved at-home testing kit (like Abbott BinaxNow, Qured, Ellume, etc.). Alternatively, our Trip Support Teams can help you identify testing providers abroad.
Looking ahead to your missions in 2022, you may want to consider On-Aircraft COVID Testing for your N-registered aircraft. It’ll make international COVID testing MUCH easier on you and your passengers when at-home testing kits aren’t an option.

A New System That Aims to Create Carbon-Neutral Aviation
Scientists have achieved an amazing breakthrough in the development of carbon-neutral fuel for the aviation industry. An aviation fuel production system that uses water, sunlight, and carbon dioxide has been put into action. Its design was published on July 20th, 2022, in the journal Joule. The dream of achieving carbon-free aviation could become a reality with this development.
“We are the first to demonstrate the entire thermochemical process chain from water and CO2 to kerosene in a fully-integrated solar tower system.” - Aldo Steinfeld, Professor, Study Corresponding Author, ETH Zurich
The aviation industry accounts for approximately 5% of the global anthropogenic emissions that contribute to global climate change. The industry heavily relies on kerosene, commonly known as jet fuel, a liquid hydrocarbon fuel derived from crude oil. There are no clean options to power commercial flights on a global scale at the moment.
Production of Synthetic Kerosene
This breakthrough, with the help of solar energy, makes it possible to produce synthetic kerosene from water and carbon dioxide instead of crude oil. The amount of CO2 emitted during kerosene combustion in a jet engine equals what is consumed during its production in the solar plant. It is what makes the fuel carbon neutral, especially if the CO2 in the air is captured and directly used as an ingredient, which could be possible in the near future.
As part of the European Union's SUN-to-LIQUID project, Steinfeld and his colleagues put forward a system that uses solar power to generate drop-in fuels—synthetic alternatives to fossil-derived fuels like kerosene and diesel. Solar-produced kerosene is consistent with the current aviation infrastructure for allocation, fuel storage, and use in jet engines. It can also combine with fossil-derived kerosene, according to Steinfeld.
High Hopes for the Future
Steinfeld and his team began scaling the construction of a solar fuel manufacturing plant at the IMDEA Energy Institute in Spain half a decade ago. The plant has 169 sun-tracking reflective panels that redirect and concentrate solar radiation into a tower-mounted solar reactor. This concentrated solar energy then powers redox reaction cycles in the reactor’s porous ceria structure, which is not absorbed but can be reused. It transforms the water and carbon dioxide into syngas, a customized mixture of hydrogen and carbon monoxide. This syngas is then injected into a gas-to-liquid converter and is finally converted into liquid hydrocarbon fuels such as kerosene and diesel. Steinfeld and his team are working on amping up the reactor’s efficiency from the current 4% to more than 15%.
