Although aviation happens to be one of the most welcoming industries with collaborations, an integral part of what drives innovation forward, it is also extremely competitive.
Always looking for the upper hand, many of aviation’s biggest companies are looking to find ways to do things quicker, cheaper and more efficiently.
And with survival sometimes positioned on a knife edge, it is perhaps no surprise that on occasions grievances that may be best kept behind closed doors, find their way into the public arena.
AeroTime looks at some of the more widely known spats and industry rivalries.
Airbus vs Boeing – the duopoly
Perhaps the most legendary rivalry in modern aviation, Boeing and Airbus, have both cemented their place as the big beasts of the sector.
While Boeing once outstripped its competitor Airbus, the roles have somewhat reversed over recent years with Europe claiming the mantle as the world’s most productive aircraft manufacturer.
In 2025, a landmark moment was achieved as Airbus’ A320 family aircraft overtook Boeing’s 737 as the most delivered jet in history.
Forever vying for aircraft orders and always looking to get ahead with new innovations and more extraordinary planes, this is one rivalry that will remain forever.
Tensions between the two have often centered around unfair advantages with grievances over tax breaks and subsidies, perhaps the most common in their storied history.
While the current generation of Airbus and Boeing executives know how to behave themselves, previous leaders have been more vocally combatant.
While there is probably an element of glee when things go wrong for the opposing side, the competition between Airbus and Boeing has undoubtably been brilliant for the industry.
Michael O’Leary (Ryanair) vs the world
It sometimes seems that Ryanair’s CEO Michael O’Leary has had a spat with every airline on the planet.
Really though it’s all part of O’Leary and Ryanair’s Modus Operandi (MO), which is essentially causing a fuss to force change or at least get some free advertising out of it.
O’Leary has said a British Airways and Iberia merger reminded him of “two drunks leaning on each other” and implied a bride was late because she was flying with Aer Lingus.
Over the years, O’Leary has hit out at Lufthansa, easyJet, the former Irish leader Bertie Ahern, his own pilots, the UK government and more recently got in a scrap with Elon Musk.
The Ryanair boss’ new number one target now appears to be Wizz Air, as the Hungarian carrier continues to make inroads in Europe.
O’Leary has described Wizz Air’s All You Can Fly program as a “marketing scam” and said the airline will “either fail or be acquired by someone”.
While Wizz Air’s CEO József Váradi has on occasion bit back, the carrier’s CCO Ian Malin recently told AeroTime ,”we have an incredible amount of respect for Ryanair and so have they for us”.
Love him or hate, O’Leary has been instrumental in turning Ryanair into what we all see today, and when he does eventually hang up his gloves, the aviation industry will be a much greyer affair for it.
United vs Delta vs American
The rivalry between United Airlines, Delta Air Lines and American Airlines is one on the most intense, hyper competitive and relentless battle in aviation.
The big three US carriers continuously try to out peg each other whether it’s over customers, loyalty, routes, hubs, products or pricing.
While United, Delta and American are undoubtably the giants of the US airline scene, there is a perception at least that American has slipped behind United and Delta in the lead.
It’s a feeling that many American staff members share after they launched an attack against the carrier’s CEO in January 2026.
Central to the argument put forward by cabin crew staff is the perception that Delta Air Lines and United Airlines are surging ahead, leaving American Airlines a distant third.
And just to prove how tense the relationships can become, this year American and United have been locked in a fight for dominance over flight schedules from Chicago O’Hare International Airport (ORD).
The bitter rivalry between the three airlines is real, and certainly isn’t going away anytime soon, so strap in.
Emirates vs Etihad vs Qatar Airways
The competition between Emirates, Etihad and Qatar Airways is one of the modern era’s greatest rivalries.
With almost a decade head start on Qatar Airways and over 20 years on Etihad, its perhaps no surprise that Emirates has grown to become the largest of the trio.
With all three strategically located in the Gulf, they have become global centers for onward long-haul travel between Europe, Asia and Australia.
With similar ways of operating the three carriers compete on price and customer experience with each vying to edge ahead by building loyalty and brand power.
The gloves rarely come off but with the war in Iran having such a profound effect on the Gulf airlines it wouldn’t be so surprising if tensions rise between the three in the near future.
Overall, competition between Emirates, Etihad and Qatar Airways has been viewed as a win-win for passengers with neither one able to gain a stranglehold on the market.
The one to watch
The biggest rivalry brewing in the aviation sector appears to be the conflict arising among the electric vehicle takeoff and landing (eVTOL) aircraft developers.
While originally positioned as a competition to be the first developer to successfully receive certification for their aircraft, it has dwarfed into something much more combatant.
While there have been some high-profile names moving from one developer to the other, it is the number of lawsuits filed against competitors that is most concerning.
In February 2026, US-based Archer Aviation sued British firm Vertical Aerospace over patent infringement of its Valo eVTOL design.
Then in March 2026, Archer escalated its legal fight with Joby Aviation, accusing its rival of concealing extensive ties to China, misleading federal regulators, and gaining an unfair competitive advantage.
This new countersuit comes after an earlier lawsuit Joby filed against Archer in November 2025. In that case, Joby accused Archer of trade secret theft and corporate espionage, alleging that Archer hired a former Joby employee who downloaded confidential company information before leaving.
All three companies have rejected accusations made against them.
In an attempt to perhaps cool rivalries, Vertical’s CEO Stuart Simpson recently sat on a panel with executives from Eve Air Mobility and Joby and called for more collaboration between developers.
“In the next 3 to 5 to 10 years, this sector, the people sitting with me together on this stage will transform how the world moves[…] And if we work together, we can bring this to life and create staggering opportunities for investors,” said Simpson.
This is in no way an exhaustive list of the current rivalries, just the ones we thought stood out – if you can think of any others let AeroTime know in the comments.
