London isn’t served by just one airport — it has six, spread across every direction of the city. That’s great for flight choice, but it also means picking the wrong one can leave you with a long, expensive journey after you land. This London airports comparison breaks down Heathrow, Gatwick, Stansted, Luton, London City and Southend, so you can match the airport to your flight, budget and final destination.
| Airport | Location | Distance from Central London | Best for | Fastest train |
|---|---|---|---|---|
| Heathrow (LHR) | West London | ~15 miles | Long-haul, international flights | Heathrow Express – 15 mins to Paddington |
| Gatwick (LGW) | South, near Crawley | ~28 miles | Leisure, European, some long-haul | Gatwick Express – ~30 mins to Victoria |
| Stansted (STN) | Northeast, Essex | ~40 miles | Low-cost European flights | Stansted Express – ~48 mins to Liverpool Street |
| Luton (LTN) | North, Bedfordshire | ~35 miles | Budget European flights | Luton Express – ~30–40 mins to St Pancras |
| London City (LCY) | East London | ~7 miles | Business travel, short-haul | DLR – direct to Bank/Canary Wharf |
| Southend (SEN) | Essex, further east | ~42 miles | Limited low-cost routes | Greater Anglia – ~53 mins to Liverpool Street |
Heathrow is the UK’s busiest airport and the natural choice for intercontinental flights. With four terminals and the widest selection of full-service airlines, it’s ideal if you’re flying from North America, Asia, or the Middle East, or connecting onward internationally. Its size means more walking and busier queues, but also the fastest express train of any London airport — 15 minutes to Paddington.
South of the city, Gatwick strikes a balance between flight variety and rail access. It handles leisure, European, and select long-haul routes, and its two terminals are simple to navigate. Direct trains reach Victoria, London Bridge, and St Pancras, making it a strong option if you’re staying in Central or South London.
Stansted is the busiest base for low-cost carriers flying short European routes. Its single terminal keeps things simple, but it’s the furthest northeast of the main three airports, so the 48-minute express train (or a coach or taxi) needs to be factored into your total journey time and cost.
Luton mirrors Stansted in many ways — mostly budget airlines, mostly European routes — but sits north of London instead. The Luton Express connects to St Pancras, putting you close to King’s Cross and Central London relatively quickly for a satellite airport.
London City Airport is the smallest and closest to Central London, just a DLR ride from Bank and Canary Wharf. It’s popular with business travellers and serves shorter routes, mainly within Europe, with smaller aircraft and quicker check-in.
Southend is the furthest out and handles the fewest routes of the six. It’s rarely the first choice unless your specific flight only operates from there, but it can be worth checking for niche low-cost routes.
The cheapest ticket doesn’t always mean the cheapest or fastest trip. A flight into Stansted or Southend might be less expensive upfront, but a longer transfer, coach fare, or taxi across a greater distance can close that gap quickly — especially for families or groups. Always add up the full door-to-door cost and time before booking.
For a closer look at the three most commonly compared options, this Heathrow vs Gatwick vs Stansted comparison breaks down terminals, train times, and which airport suits which part of London in more detail.

Heathrow and Gatwick cover the widest range of routes with the strongest rail links; Stansted and Luton are best for budget European travel; London City suits short business trips near the centre; and Southend is a niche option for specific routes. Match the airport to your trip, not the other way around.
