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.

Airline reviews

Crew was wonderful. I knew going in that the seats were not lie-flat in business class, but they reclined less than I expected. To save on waste, you have to ask for which pieces of the amenity kit you are interested in, which they will gladly give to you. Flight was fairly short, so no issues. I did have one piece of luggage not show up at terminal on landing. They were great about looking for it. Found it...it actually did make the flight and was listed as "not picked up" (?????--we stayed over an hour looking for it, including in the odd-sized baggage claim.) Since "not picked up" they will not ship to my house and I have to go back to airport, which is in another town. I probably could have pressed this issue, but headed back to airport for another flight anyway, so will pick up then.

It didn't happen. Icelandair cancelled the flight from Nuuk, Greenland to Reykjavik, Iceland so I couldn't fly to Portland. Additionally Icelandair rebooked me on a flight that got cancelled too.

How can the airline deploy the oldest 757-200 with a broken down entertainment system and no WiFi for a cross Atlantic 7:50 hr torture chamber experience?? My seat 3A couldn’t be reclined. The footrest was flimsy and useless. And there’s no leg support unlike their newer 737-Max which they lavish on intra-Europe routes. Shame!!

Only drinks included in economy class was water and coffee seat on the 737 were hard as rock. The landing and passport control in Iceland are the worst I have ever seen. 2 hours to clear customs ???? 3 attendants at pass port control out of more than a dozen closed. I” ll never fly to Iceland or transfer through this airport again.

The ticket was reserved in my name but not paid for by underpricer. Alaska airlines was unable to issue my ticket (could not connect the ticket with the PNR) due to an error with underpricer and I spent the better part of 2 hours at the ticket counter trying to rectify.

Terrible way of boarding in Reykjavik. Seats comfortable. Meal was good.

Unlike my prior three connections on this latest journey, this flight was fairly good. Only issue was boarding as it was once again one of those Icelandic issues of bunch up, walk in the rain to a bus that then has you run up three flights of stairs to board the plain. I was in Saga class but the bus scramble eliminates any chance you get on first and have to then find a place to squeeze your carry on into an overhead that the people in economy populate so they can grab it on their way out up front. But unlike other Icelandic flights this journey I did find more the of the business class like accommodations then the other air segments. This one found a pillow and blanket waiting for me and I actually received a small cup of sparkling wine and had a bottle of water in place. Service was attentive and the flight departed and arrived on time. Received a menu and had choices of a hot or cold meal. I choose the hot which was cod and it was good. Decent size portion, salad and a choice of dinner rolls. Beverage menu was a selection of wines, beer and soft drinks. Desert was a small Tiramisu. Overall the six hour flight was a good experience for the price point.

We paid for saga class, which is the business class for international. My seat was broken and did not recline and my monitor for in-flight entertainment was broken.

The flight itself was fine, even with a one-hour delay leaving on the Reykjavik tarmac (the lost time was made up during flight). Our experience at the Reykjavik airport on arrival was terrible due mostly to the one hour it took for passport control. Only two stations were open for our category, and the room was full with a huge crowd.

Awful. The Iceland airport was a complete mess. Boarding was a chaotic, the seats were awful, there was a group of rowdy 20 something men in our row hooting and hollering, ordering alcoholic drink after drink. Yelling and laughing at the top of their lungs and the crew just went along with it. Passengers complained to the men, asking if they could keep it down (it was a night time flight so people wanted to sleep). They never listened crew continued to laugh with them, flirt with them and serve them more drinks. No free food or snacks, seats were horribly uncomfortable. Worst flight I've had in a long time
