Cheap flights from London to Phoenix

November is the cheapest month to fly this route, and the quieter weeks either side of it often hold up well too. Late autumn and the first half of December are calm in both cities; from mid-December the US holiday rush starts and fares climb. Spring is a good middle ground, with London mild and Phoenix warm but not yet punishing. Summer is the hard one: Phoenix heat peaks and London school holidays push prices up, so book well ahead. Flying midweek, on a Tuesday or Wednesday, usually costs less than a weekend departure. Book a few months out for summer and holiday travel; for November, a shorter lead time often works.

The airlines selling this route are full-service carriers rather than budget ones: Air France, KLM Royal Dutch Airlines, Lufthansa City Airlines, Austrian, Brussels Airlines, Finnair, Air Canada, WestJet, Air Dolomiti and Edelweiss Air. That means the difference between a cheap-looking fare and a flexible one is usually the fare family, not the airline: hand baggage only versus a checked bag, a seat you can choose versus one assigned at check-in, and whether a change is allowed. The European carriers connect in their home hubs, while WestJet and Air Canada route you through Canada. Check whether the whole trip sits on one ticket: if it does not, a missed connection is yours to sort out.

Phoenix is served by Sky Harbor International, which sits just outside the downtown core, so the transfer into the city is short by the standards of a big US airport. Taxis and rideshares wait at the terminals, hotel shuttles run to the main downtown and Scottsdale properties, and the light rail links the airport area with central Phoenix. If you are connecting onward, note that Sky Harbor has several terminals and the airline on your ticket decides which one you land at. Build in time on arrival: passport control and customs at a US gateway can take a while, especially when several long-haul flights land at once.

Country facts: Wikidata

• Check which London airport your ticket uses: Heathrow, Gatwick, Luton, Stansted and London City are far apart, and a fare from the wrong one costs you a transfer.
• Confirm whether a checked bag is included, because the lowest fares on this route often cover hand luggage only.
• If your trip sits on two separate tickets, leave a long gap, since the second airline will not rebook you after a missed connection.
• Make sure your passport and US travel authorisation are valid before you pay.
• Compare November fares with the weeks either side and check whether a midweek departure is cheaper.
• Decide whether you want a nonstop into Sky Harbor or a connection through a European or Canadian hub.
