FAQs for booking flights from the United Kingdom to Alaska

  • I’m booking a flight to Alaska for a glacier cruise. Which airport do I choose?

    Glacier cruises in Alaska depart from the coastal cities of Anchorage or Juneau. Both cities’ international airports are served by flights to Alaska via Seattle-Tacoma International Airport, operated by Alaska Airlines. However, if you’re flying on another airline or are planning a stopover in another city in the United States, choosing Anchorage Airport is the best option.

  • Which airport is closest to the Kenai Fjords National Park?

    Ted Stevens Anchorage International Airport is the closest to the Kenai Fjords National Park, approximately 2h 15min away by car. Exit Glacier is one of the most popular areas of the park, but do check any warnings before travelling here, especially if you’re booking a last-minute flight to Alaska to visit the Kenai Fjords National Park. Some areas of the park might be closed at short notice due to potential icefalls.

  • I’m travelling to Alaska to see the Northern Lights. Which airports should I choose?

    One of the best places in Alaska to view the Northern Lights is in Fairbanks, which is served by Fairbanks International Airport. This airport is served by regular flights operated by Alaska Airlines from Seattle Tacoma and Anchorage. If you want more options for stopovers when flying from the UK, there are also some seasonal flights from Minneapolis-St. Paul International Airport (MSP), Chicago O’Hare International Airport (ORD) and San Francisco International Airport (SFO).

  • How do I book a flight to visit the Arctic Coast?

    The city closest to the Arctic Coast is the northernmost city of Utqiagvik (Barrow), served by the Wiley Post-Will Rogers Memorial Airport (BRW). This airport is served by regular domestic flights from Anchorage and Fairbanks, operated by Alaska Airlines. Booking a flight to Barrow from anywhere in the United Kingdom involves multiple airlines and at least two stopovers since Alaska Airlines doesn't operate direct flights to Alaska from the UK.

  • How does KAYAK find such low prices on flights from the United Kingdom to Alaska?

    KAYAK is a travel search engine. That means we look across the web to find the best prices we can find for our users. With over 2 billion flight queries processed yearly, we are able to display a variety of prices and options on flights from the United Kingdom to Alaska.

  • How does KAYAK's flight Price Forecast tool help me choose the right time to buy my flight ticket from the United Kingdom to Alaska?

    KAYAK’s flight Price Forecast tool uses historical data to determine whether the price for a flight from the United Kingdom to Alaska is likely to change within 7 days, so travelers know whether to wait or book now.

  • What is the Hacker Fare option on flights from the United Kingdom to Alaska?

    Hacker Fares allow you to combine one-way tickets in order to save you money over a traditional round-trip ticket. You could then fly from the United Kingdom to Alaska with an airline and back with another airline.

  • What is KAYAK's "flexible dates" feature and why should I care when looking for a flight from the United Kingdom to Alaska?

    Sometimes travel dates aren't set in stone. If your preferred travel dates have some wiggle room, flexible dates will show you all the options when flying from the United Kingdom to Alaska up to 3 days before/after your preferred dates. You can then pick the flights that suit you best.

Top tips for finding a cheap flight out of the United Kingdom

  • Alaska is served by three main airports: Fairbanks International Airport (FAI), Ted Stevens Anchorage International Airport (ANC) and Juneau International Airport (JNU). If you want to select an airport with the most flight options from the UK, Anchorage has the most direct flights to Alaska from other destinations in the United States.
  • There are no direct flights to Alaska from the United Kingdom, so you’ll always need to plan for one or two stopovers. The most frequent stopover airports for passengers travelling to Anchorage are Los Angeles International Airport (LAX) and Seattle-Tacoma International Airport (SEA).
  • Even though Juneau is the capital city of Alaska, its airport has fewer options when it comes to airlines and routes. When booking flights to Alaska that land at this airport, you'll be limited to Alaska Airlines and a stopover in either Seattle or Anchorage.
  • Many people travel to Alaska from June to September, which is a popular time for whale watching, or from September to April, when most people travel to Alaska to experience the Northern Lights. If any of these nature-related activities is on your radar and you’d like to combine both in the same trip, it’s best if you start looking for flights as far in advance as possible.
  • UK citizens can travel to the United States visa-free if they're visiting for fewer than 90 days, but they still need a valid passport. Passengers travelling for tourism should apply for an ESTA, the Electronic System for Travel Authorisation, in advance.

The Icelandair crew was so kind!!! Thank you for making my first trip to Paris a great one!

I am not going to fillo this out for each leg of my trip. My first review holds for the experience

The most uncomfortable seat i’ve ever had on a flight

Waiting area on top of stairs before Boarding the bus wasn’t great. Took a long time to load the bus to gate.

The real reason why the flying experience with Icelandair ---was mediocre was because of not being able to enter DC airspace yesterday evening. This obviously was out of your control and do realize this is a safety issue. I did notice---that everything was being done to get us to Washington Dulles and we did arrive at Dulles SAFELY with just a 4 hour delay. Thank you!

Nice, quick flight. There were lots of empty seats so they told me I could sit next to the emergency exit where I would have more legroom.

The staff was kind and helpful. There was no food, and you needed to bring your own earphones to use the entertainment, which I didn’t know.

They wouldn’t check in my luggage even though I had one checked bag prepaid. So I took my bag to the gate and tried to check it in there and two employees scolded me for bringing a large bag to the gate. I told them I was trying to check it in and that it was prepaid, and they said they couldn’t guarantee that it would arrive at my destination but they finally let me drop it off when boarding the plane and pick it up right after exiting the plane. There was no food, and there was no entertainment.

Overall satisfied and would fly with them again. They could improve the check-in efficiency at BOS, we got backed up because it seemed there were passengers requiring much more time for check in.

The customer service was unbeatable from the wheelchair assist team to the flight attendants. The pilot also did an excellent job managing the turbulence.
