London to Cancún (LGW–CUN) — Airlines, Schedules & Connections

British passport holders enter Mexico visa-free for up to 180 days. No fee, no advance application. Passport must be valid for the duration of the stay. On the aircraft or at the border, you receive a Forma Migratoria Multiple (FMM) card. The digital version is available at inm.gob.mx and can be completed before arrival.

Do not lose the FMM slip. You must return it when leaving Mexico. A replacement costs roughly MXN 600 (about $35) and involves a trip to an INM (immigration) office. Immigration officers sometimes stamp fewer than 180 days; if you need the full allowance, politely request it at the counter. No supporting documents are required beyond a valid passport.

Direct flights from London Heathrow to Mexico City (MEX) run about 11 hours 30 minutes on British Airways and Aeromexico. The Mexican peso (MXN) trades at roughly 17 MXN per $1. ATMs give better rates than exchange bureaus; avoid airport booths. No vaccination requirements for UK arrivals. Mexico City sits at 2,240m elevation, so altitude effects (headache, fatigue) hit some people on day one. Tap water is not drinkable; buy garrafones (20L jugs) or bottled water.

The Gatwick Express runs non-stop from London Victoria to the South Terminal in 30 minutes, with trains every 15 minutes (from £21.50 one-way; advance fares cheaper online). Thameslink trains from London Bridge, Blackfriars, City Thameslink, and Farringdon are slower (35–45 min) but significantly cheaper; often £10–13 on Oyster or contactless. Southern trains also serve the route.National coaches (National Express, Megabus) connect Gatwick to Victoria Coach Station for £6–15. Taxis from central London cost £70–100+ depending on traffic. Driving via M23 and A23 takes 35–60 minutes; multi-storey car parks are directly connected to both terminals by a 2-minute monorail shuttle.

Authorised airport taxis operate from a voucher desk inside each terminal. Fares to the Hotel Zone run MXN 350–550 (USD $17–28) and to downtown Cancún MXN 200–300. Purchase tickets inside before exiting to avoid touts. ADO buses depart from outside Terminal 2 to downtown Cancún for MXN 102 and continue to Playa del Carmen and Tulum.The Tren Maya connects Terminal 4 to Playa del Carmen, Tulum, and the broader Yucatán Peninsula. Car rental desks are located in all terminals; driving is straightforward on Highway 307.

Tropical climate with two distinct seasons. Dry season (December–April) brings warm, sunny weather at 25–32°C with low humidity, the peak tourist season and most reliable flying conditions. Wet season (May–November) is hot, humid, and prone to heavy afternoon downpours; thunderstorms can cause short ground delays.

Hurricane season runs June through November, peaking in September–October. Major storms (e.g., Wilma 2005, Zeta 2020) can close the airport for 12–48 hours. Monitor forecasts carefully from August through October. September is statistically the highest-risk month.
