Fares from London to Cancun (GBP)
Cancun’s dry season (December to April) brings the best weather, the biggest crowds and the highest fares, peaking over Christmas and around spring break. The summer and autumn (June to November) fall in the Atlantic hurricane season, so prices ease even though most days stay sunny. The table below shows when the route is busiest. We no longer print per-month fare estimates here, because they were never measured.
| Month | Demand |
|---|---|
| January | very high (dry season) |
| February | high (half-term) |
| March | high (spring break) |
| April | high (Easter) |
| May | medium |
| June | low-medium |
| July | medium (summer holidays) |
| August | medium |
| September | low |
| October | low-medium |
| November | medium |
| December | very high (holidays) |
We do not quote a target fare for this route. Our price tracking holds no recorded observations for it, so a “typical” or “good deal” figure here would be an estimate dressed up as a measurement — so this page leaves it out rather than guess. The seasonal pattern above is the part we can stand behind; check the live fare for the number.
Airlines on this route
Non-stop (about 11 hours):
- British Airways — non-stop from Gatwick on the Boeing 787, roughly daily year-round.
- TUI Airways — non-stop from Gatwick, several times a week, popular with package holidaymakers.
One-stop (often cheaper, about 15–20 hours total):
- Iberia via Madrid — a short first hop and a single onward flight; frequently among the best-value fares.
- Air France via Paris and KLM via Amsterdam — comfortable European routings that avoid a US connection.
- American Airlines and United via US hubs (Dallas, Miami, Houston) — often cheap, but any US connection needs an ESTA even if you never leave the airport.
The European one-stops are usually the smoothest way to save, since they skip the US transit rules. Compare the all-in price, including bags, before you decide.
When to book & how to save
- Book 3–5 months ahead for the best balance of price and choice; long-haul fares to Cancun rarely improve at the last minute.
- Prefer a European connection (Iberia, Air France, KLM) if you want to skip the US ESTA requirement that comes with an American or United routing.
- Travel in the low season (May, September, October) for the cheapest fares — hurricanes are possible but most days are still sunny and hot.
- Avoid the peaks: Christmas, February half-term, spring break and Easter are the most expensive and busiest weeks.
- Check checked-bag rules: BA and TUI include a checked bag on most fares, but the cheapest “light” tickets may not — compare the all-in price.
Arriving in Cancun
Flights land at Cancún International (CUN), about 20 km south of the city and the Hotel Zone, with several terminals (most UK non-stops use Terminal 3 or 4). The cheapest way into town or down the coast is the ADO airport bus (to Cancún centre or Playa del Carmen, a few pounds), while pre-booked private transfers and authorised airport taxis run to the Hotel Zone for roughly £20–£40. Agree the fare before you get in, and ignore the touts inside arrivals. Mexico uses the peso, so carry a little local cash for tips and buses.
