London Airports Comparison: Heathrow, Gatwick, Stansted, Luton & More Meta
London Airports Comparison: Which One Should You Fly Into?
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.
London Airports at a Glance
| 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: The Long-Haul Hub
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.
Gatwick: The All-Rounder
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: The Budget Airline Base
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: Another Budget-Friendly Option
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: Closest to the Centre
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: The Quiet Option
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.
How to Choose the Right London Airport
- Flying long-haul or connecting internationally? Heathrow.
- Flying a European leisure route with good rail access? Gatwick.
- Booked the cheapest possible European fare? Likely Stansted or Luton — just check the transfer time.
- On a short business trip needing to be near the City or Canary Wharf? London City.
- Flight only available from a smaller airport? Southend, but confirm your onward transport in advance.
Look Beyond the Airfare
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.

Final Thoughts
There’s no single “best” London airport — only the one that best matches your flight, your budget, and where you’re actually staying. 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.
