Multi-Airport Cities Guide: Comparing LHR, LGW, STN, LTN & LCY

In global aviation systems, major cities served by more than one commercial passenger airport are assigned an overarching metropolitan city code alongside individual 3-letter airport IATA codes. For example, `LON` covers London Heathrow (`LHR`), London Gatwick (`LGW`), London Stansted (`STN`), London Luton (`LTN`), and London City (`LCY`); `PAR` covers Paris Charles de Gaulle (`CDG`) and Paris Orly (`ORY`); and `NYC` covers New York John F. Kennedy (`JFK`), Newark Liberty (`EWR`), and LaGuardia (`LGA`).

Searching with a metropolitan code is an excellent way to discover lower fares across the entire region. However, before you click through to book an itinerary on an external provider, you should always check the specific 3-letter airport code on both the outbound and return legs. It is surprisingly common for a mixed-carrier round-trip ticket to depart from London Heathrow (`LHR`) and return two weeks later into London Gatwick (`LGW`)—a crucial detail if you parked your car at Heathrow!

London Heathrow (`LHR`), 23 km west of Central London, is the UK’s primary intercontinental hub, served by the Elizabeth line (direct to Paddington, Bond Street, Tottenham Court Road, Farringdon, Liverpool Street, and Canary Wharf), the 15-minute Heathrow Express to Paddington, and the Piccadilly Underground line. If you are flying non-stop to Mumbai (`BOM`), New Delhi (`DEL`), Bengaluru (`BLR`), Singapore (`SIN`), Dubai (`DXB`), or New York (`JFK`), Heathrow offers the deepest schedule frequency.

London Gatwick (`LGW`), 47 km south of Central London, is exceptionally well connected by mainline rail: Thameslink trains run directly through Central London (St Pancras International, Farringdon, City Thameslink, Blackfriars, and London Bridge), alongside Southern and Gatwick Express services to London Victoria. For South London, Surrey, Sussex, and Brighton residents, Gatwick is often faster to reach than Heathrow.

London Stansted (`STN`, 64 km northeast, ~48 minutes via Stansted Express to Liverpool Street) and London Luton (`LTN`, 51 km northwest, connected via Luton Airport Express / Thameslink to St Pancras plus the Luton DART automated shuttle) are dominated by European point-to-point low-cost carriers, though Stansted also hosts long-haul connections via Dubai. Finally, London City Airport (`LCY`, 11 km east in the Royal Docks on the DLR) caters to rapid short-haul business flights to European financial centres like Frankfurt (`FRA`) and Amsterdam (`AMS`).

To make an accurate comparison between two airports in the same city, add three numbers together for every passenger in your group: (1) the ticket price including your required cabin and hold bags, (2) the round-trip rail, Underground, coach, or taxi fare to that terminal, and (3) whether an early departure requires an overnight airport hotel stay.

For a solo traveller with a backpack living near Liverpool Street Station, a low-cost European flight from Stansted can be unbeatable. For a family of four travelling with checked suitcases from West London, paying £25 more per ticket to fly from Heathrow on the Elizabeth line or Piccadilly line often saves money and eliminates an hour of cross-city rail transfers.

Some multi-airline search combinations propose “split-airport” connections—where you land at London Heathrow (`LHR`) on a transatlantic or Asian flight and depart from London Gatwick (`LGW`) a few hours later (or land at Paris `CDG` and depart from Paris `ORY`).

Remember that an inter-airport connection is a full landside transfer: you must pass through national border control (requiring a valid UK ETA/visa or Schengen visa if applicable for your passport), wait for your checked bags at the carousel, board a highway coach or cross-city train at your own expense, and check in again at the second airport before bag-drop closes. Unless you have at least 4 to 5 hours between flights and a compelling reason, selecting a single-airport connection at `LHR`, `LGW`, `CDG`, `FRA`, or `AMS` is far safer.
