Cheap flights London to Guadalajara

January is the cheapest month to fly this route, and the weeks just after the New Year holidays are the quietest. Fares climb through spring and stay high all summer, when Mexican families travel and London schools are out. Midweek departures, Tuesday or Wednesday, usually cost less than a Friday or Sunday. Book well ahead for summer and December; leave it later for January and early February, when demand drops. Mexican holidays around Easter and the Day of the Dead fill planes heading the other way, so your return date matters as much as your outbound one.

No low-cost carrier flies between London and Guadalajara, so every option is a full-service airline. British Airways, Iberia, Lufthansa, Swiss, KLM Royal Dutch Airlines, Finnair, Air Canada and AeroMéxico all sell this route, with Lufthansa City Airlines and Air Dolomiti on some legs. Since there are no nonstop flights, you change planes at least once, and the number of stops is what separates a quick trip from a long one. Baggage rules follow the fare family, not the airline: the lightest economy fares often exclude a checked bag, while a flexible ticket includes one. Check the layover airport and the connection time before you choose.

Every flight on this route lands at Miguel Hidalgo, the airport that serves Guadalajara, and it sits a short ride from the centre rather than far out of town. Taxis and ride-hailing apps wait at arrivals, and local buses run into the city for less. If your connecting flight stops somewhere else in Mexico first, you clear immigration and customs at that first Mexican airport, so keep your documents and onward boarding pass within reach. Allow time for the queue at immigration on busy evenings, and agree the pickup point with your driver before you walk out, since the arrivals area gets crowded.

Country facts: Wikidata

• Check which London airport your fare uses: Heathrow, Gatwick, City, Luton and Stansted are not interchangeable.
• Confirm whether a checked bag is included, since the lightest fares on this route often exclude one.
• Look at the layover airport and its length, because a tight connection is where these trips usually go wrong.
• Keep both legs on one ticket, so a delayed first flight does not leave you stranded.
• Check your passport and Mexico's entry rules well before you fly, and book January if your dates are flexible.
