Biggest Airlines in the UK - Top 5 Largest Carriers
Most people likely think that the largest airline in the UK is either easyJet or British Airways. And those people are correct. We reviewed 4 main categories to see which UK airline serves the most passengers and destinations, which earns the most revenue, and which has the largest fleet. The result? A tie.
After 4 different factors, easyJet and BA were tied, and the ultimate tie-breaker, the number of daily flights, resulted in an overall winner. We can confidently say that easyJet is the UK’s biggest airline with British Airways a very close second.
How did we arrive at these results? Read on to find out and see just how close the other 3 airlines are in the top 5 ranking.

Airline | Total Points (out of 20) |
easyJet | 18 |
British Airways | 18 |
Jet2.com | 11 |
TUI Airways | 9 |
Virgin Atlantic | 4 |
As mentioned, to break the tie, we reviewed the average daily flights of the top 2 carriers and easyJet came out on top by quite a margin (more on this later). Note that Virgin Atlantic scored the lowest in each category and Jet2 is the closest to challenging for a top place.
Biggest UK Airlines - Passengers
1st Place: easyJet
In 2023, easyJet transported over 82 million passengers, nearly double British Airways' total. Virgin Atlantic welcomed just over 5 million travellers on their planes, showing the significant discrepancy from the top of the list to the bottom.

Largest UK Airlines - Fleet Size
1st Place: easyJet
The number of passenger (not cargo) aircraft owned and operated by a carrier is another good size indicator. Our winner for this factor is easyJet again. This airline has nearly 350 planes to choose from, which will generally translate to a better selection of flights for the public.
The overall ranking for fleet size mirrors the passenger numbers ranking, which makes sense. More planes = a larger capacity to serve passengers.
Airline | Total Passenger Fleet Size | Effective Date (as of) |
easyJet | 347 | September 2024 |
British Airways | 253 | January 2025 |
Jet2.com | 117 | January 2025 |
TUI Airways | 67 | December 2024 |
Virgin Atlantic | 45 | December 2024 |
Biggest UK Airlines - Annual Revenue
1st Place: British Airways
Another good indicator of an airline’s size is its total revenue. Using published 2023 numbers, we found that this is one category where easyJet is not the largest airline in the UK. That honour goes to British Airways with over £14 billion.
With this metric, you really see the difference between a low-cost airline and a flag carrier. Although easyJet has more planes and more passengers, in 2023, the airline reported about a third of BA’s revenue at £5.2 billion. This significant difference can be attributed to things like operating inefficiencies, but it’s likely mostly related to easyJet’s lower fare prices.
As a member of a larger airline company, we determined that TUI UK + Ireland was responsible for 27% of the TUI Group’s total business. As a result, their approximate UK revenue was £4.69 billion.
Other than the top 2 places, the remaining rankings stayed the same.
Airline | Reported 2023 Annual Revenue (billions) |
British Airways | £14.3 |
easyJet | £5.2 |
Jet2.com | £5.03 |
TUI Airways | £4.69 |
Virgin Atlantic | £3.1 |
Largest Airlines in the UK - Destinations
1st Place: British Airways
A bigger destination list means more options for passengers and the wider the airline’s reach, the more useful it becomes to a larger selection of travellers. BA serves more than 200 worldwide destinations, whereas easyJet falls short due to its focus on short-haul flights predominantly in Europe.
But easyJet is trying to give BA a run for their money. In November 2024, the airline announced an expansion with its first-ever Sub-Saharan route to Cape Verde. Ali Gayward, the UK Country Manager for easyJet commented:
Our continued growth and investment in the UK and the connectivity we offer our customers highlights the importance of the market for us, where this year we operated more flying than ever before. So with 21 new services now available from ten airports across the UK, our flights and holidays are available to even more new destinations next summer, providing customers with even more fantastic choice and great value.
TUI UK gains a place here with more available destinations than Jet2.com, and Virgin Atlantic remains at the bottom, with 35.
Airline | Destinations Served |
British Airways | 201 destinations, 79 countries |
easyJet | 165 airports, 35 countries |
TUI Airways | 100+ |
Jet2.com | 75 |
Virgin Atlantic | 35+ |
UK’s Biggest Airline - Average Daily Flights (Tie-Breaker)
1st Place: easyJet
Since to this point BA and easyJet are dead-locked at winning 2 categories each, we used the average flights per day to decide on the overall winner.
British Airways averaged 789 daily flights in 2023 according to Eurocontrol. EasyJet on the other hand nearly doubled that amount with an average of 1,477 flights per day during the same period. EasyJet’s month with the most flights in 2023 was August, with 54,246 total, which is a monthly average of 1,749 daily departures. They certainly keep busy!
