Heathrow Airport is London and the UK’s main airport. The airport plays host to the flag carrier of the UK, in addition to welcoming a number of foreign airlines. However, Heathrow lacks low-cost carrier activity, which London Gatwick does not. Additionally, Heathrow is also more desirable to carriers. Let’s dissect the airports to find out which is the best, comparing connections to London, size, and variety.

Connections to London

In terms of connections to London, the two airports are vastly different. Gatwick is located 24 miles south of London, and is accessible by both the Gatwick Express and mainline Thameslink trains. It takes around half an hour to get into London using the Gatwick Express, however mainline trains may take longer, but connect to more destinations past London such as Peterborough and Luton.

On the other hand, London Heathrow is only 13 miles west of the city centre. As such, the time taken to reach the airport is around 15-20 minutes on the Heathrow Express. The Heathrow Express can be pricey, however there is also TFL Rail, and the Piccadilly Line taking passengers into London for less. Soon, the airport should be connected to the Elizabeth Line, providing direct connections across London. Given these facts, it seems like Heathrow is certainly the winner in terms of London connections.

Measuring the airports in terms of size also gives a clear winner. According to CAA statistics, in 2018 Heathrow Airport carried a total of 80,124,537 passengers across 477,604 aircraft movements. Gatwick had just over half of this figure at 46,086,089 passengers with 283,919 aircraft movements.

While London Gatwick is aiming to be able to use its spare runway in the future, right now it has only one useable runway. London Heathrow, on the other hand, has two permanent runways and is currently trying to secure a third. Finally, Heathrow Airport has an impressive five terminals, compared to Gatwick’s two. As such, Heathrow airport wins on size.


Variety is a close call. While Heathrow Airport undoubtedly has much more variety with more long-range international carriers, London Gatwick has a wider variety of types of operations. Indeed, Heathrow lacks the low-cost element of Gatwick Airport, which sees operations by Ryanair, Easyjet, and Vueling. As such, It is a draw between the two.

The best airport for UK travelers often comes down to where they want to go and who they are flying with. Where they are coming from in the UK can also make a difference. While there are many more factors to be considered, it seems like London Heathrow is the clear winner with the criteria we have investigated.
