London has six airports — so which London airport should you fly into? The right choice depends on your budget, where you are staying, and which airlines serve your US departure city. This guide compares every London airport so American travelers can make the best decision.
Remember: regardless of which London airport you use, you need a UK ETA to enter the United Kingdom.
London Airports at a Glance: Which London Airport to Fly Into
| Airport | Code | Distance to Central London | Transfer Time | Best For |
|---|---|---|---|---|
| Heathrow | LHR | 15 miles west | 15-60 min | Most US flights, business travelers |
| Gatwick | LGW | 30 miles south | 30-60 min | Budget US airlines, south England trips |
| London City | LCY | 6 miles east | 20-30 min | Business trips to Canary Wharf/City |
| Stansted | STN | 40 miles northeast | 50-90 min | European budget connections |
| Luton | LTN | 35 miles north | 40-60 min | European budget airlines |
| Southend | SEN | 40 miles east | 55-75 min | Very limited routes |
Heathrow Airport (LHR) — Best for Most American Travelers
Heathrow is the obvious choice when deciding which London airport to fly into from the US. Here is why:
- Handles 95%+ of nonstop US flights — British Airways, American Airlines, United, Delta, and Virgin Atlantic all fly here from multiple US cities
- 5 terminals — Terminal 5 (British Airways) and Terminal 2 (Star Alliance) are the most modern
- Best transport links:
- Elizabeth Line (Crossrail): £12.80 to central London, approximately 40 minutes to Paddington or Liverpool Street. Best value option
- Heathrow Express: £25, just 15 minutes to Paddington station. Fastest but priciest
- Piccadilly Line (Tube): £5.50 with Oyster/contactless, approximately 60 minutes to central London. Cheapest option
Verdict: If you have a nonstop flight from the US, it almost certainly lands at Heathrow. Choose it for convenience, transport options, and the widest range of US flights.
Gatwick Airport (LGW) — Budget Alternative
Gatwick is London’s second-largest airport and an increasingly popular option for budget-conscious American travelers:
- JetBlue flies nonstop from JFK to Gatwick — often significantly cheaper than Heathrow routes
- Norse Atlantic offers budget nonstop flights from several US cities to Gatwick
- Transport to London:
- Gatwick Express: £19.90, 30 minutes to Victoria station
- Thameslink/Southern trains: £12-15, 30-45 minutes to various London stations including London Bridge and St Pancras
- Great for: Travelers heading to south London, Brighton, or the south coast
Verdict: If you find a significantly cheaper fare to Gatwick (especially on JetBlue or Norse), it is worth considering. The rail link to central London is fast and reliable.
London City Airport (LCY) — Business Traveler’s Choice
London City is the smallest major London airport but has one unique advantage — it is just 6 miles from the City of London financial district:
- Limited US routes — primarily short-haul European flights and some domestic routes
- DLR (Docklands Light Railway): Quick connection to Bank station and Canary Wharf
- Best for: Business travelers with meetings in the City or Canary Wharf
- Note: Very few (if any) nonstop US flights. You would typically connect through a European hub
Stansted and Luton — Not for US Arrivals
Stansted (Ryanair hub) and Luton (easyJet/Wizz Air) primarily serve European budget airlines. They have no nonstop US flights and are further from central London. You would only use these if:
- You are connecting from a European city on a budget airline
- You are taking a side trip to Europe during your UK visit
Transport from both airports is slower and less convenient than Heathrow or Gatwick.
Which London Airport to Fly Into: Decision Guide
| Your Priority | Best Airport | Why |
|---|---|---|
| Most flight options from US | Heathrow | 95%+ of US nonstop flights |
| Cheapest fares from US | Gatwick | JetBlue and Norse budget fares |
| Fastest to central London | Heathrow | 15 min on Heathrow Express |
| Closest to City/Canary Wharf | London City | 6 miles, DLR direct |
| Heading to south England | Gatwick | Closer to Brighton, coast |
| Continuing to Europe | Stansted/Luton | Budget European connections |

FAQ: Which London Airport to Fly Into
Which London airport do most US flights land at?
Heathrow (LHR) handles the vast majority of nonstop transatlantic flights from the US. British Airways, American Airlines, United Airlines, Delta, and Virgin Atlantic all operate extensive US routes to Heathrow.
Is Gatwick or Heathrow better for Americans?
Heathrow offers more US flight options and faster transport to central London. Gatwick is better if you find a significantly cheaper fare (JetBlue, Norse Atlantic) or if you are heading to south England.
Do I need a UK ETA regardless of which airport I use?
Yes. The UK ETA is required at every UK airport and port of entry, no exceptions.
What is the cheapest way from Heathrow to central London?
The Piccadilly Line (Tube) costs £5.50 with Oyster/contactless and takes about 60 minutes. The Elizabeth Line costs £12.80 and takes 40 minutes — the best balance of speed and value.
Can I take the Tube from Gatwick?
No. Gatwick is not on the Tube network. You need the Gatwick Express train (£19.90, 30 min to Victoria) or a Thameslink train (£12-15, 30-45 min).
Which airport is closest to central London?
London City Airport (LCY) at just 6 miles, but it has very few US flights. Among airports with US service, Heathrow is closest at 15 miles.
