Cheap flights from London to Anchorage

May is the cheapest month on this route, and late spring generally undercuts the summer rush. Alaska's high season runs from June through August, when fares climb along with the daylight; September and October bring cheaper seats back as the crowds thin. Winter travel from December to February is quiet on the London end but can be disrupted by snow on the Anchorage side. Midweek departures, especially Tuesday and Wednesday, usually cost less than a weekend flight, and the same goes for the return. For summer travel, book well ahead; for winter, you can often leave it later and watch the calendar.

Every itinerary on this route is connecting, so the airline you choose decides where you change and how long you wait. Icelandair, Air Canada, KLM Royal Dutch Airlines, Air France, Austrian, Brussels Airlines, Finnair, WestJet, Virgin Atlantic and Delta Air Lines all sell London to Anchorage with a stop, and the total journey time matters more than the headline fare. These are full-service carriers rather than low-cost airlines, but what is included still varies: baggage, seat selection and change rules depend on the fare family you buy, and the allowance can differ between the two airlines on a single ticket. Mixing carriers is common, so keep the whole trip on one booking.

Anchorage International is the only airport on the Alaska end of this route, so every itinerary lands there and there is no second airport to weigh up. It sits close to the city, and the ride into town is a short one by the standards of a long-haul arrival, with taxis, ride shares and hotel shuttles the usual options. On a connecting trip you normally clear US immigration and customs at your first stop on American soil, not in Anchorage, so check where that happens and leave a comfortable gap between flights. Confirm at check-in whether your bags are tagged through to Anchorage or have to be collected at the transfer point.

Country facts: Wikidata

• Choose your London airport first, since Heathrow, Gatwick, City, Luton and Stansted all serve this route and switching between them is slow.
• Check whether the connection is on one ticket or two, as a self-transfer means collecting your bags and carrying the risk of a missed leg.
• Confirm the baggage allowance on each leg, since the rules can differ between airlines on one itinerary.
• Make sure your passport and US entry authorisation are valid before you book, and check the rules again closer to departure.
• Weigh May against the summer weeks, as the cheapest fares and the busiest dates do not overlap.
