Insights shared by verified travellers who flew the route from Seattle to England 
MichaelFlew with Delta-May 2026
We like Delta, Alaska and American. Be prepared for a bit of a trek from your arrival gate to Customs and outside services. Heathrow doesn't rank high on my list of major airports.
Verified travelerFlew with American Airlines-Apr 2026
Heathrow is too gigantic to have less than 2 hours of layover time.
Verified travelerFlew with British Airways-Apr 2025
Make sure you have plenty of time between flights if you are delayed.
Verified travelerFlew with British Airways-Feb 2025
Don’t take a flight if you sick, or if you have no choice prepare to stay covered with mask throughout the flight
Verified travelerFlew with British Airways-Apr 2024
Bring a sack lunch -- airport food was very expensive.

Delays. Again. Haven’t had a good experience out of Seattle in most flights. The flight was delayed and passengers were all bunched in one area even after the doors closed when there were tons of empty seats. Attendants chastised passengers for wanting to move and even embarrassed one man for telling him tons of the empty seats were actually premium seating and he needed to go back to the back of the plane the seats have been getting increasingly uncomfortable and the snacks are terrible if you get one. No options for people who don’t/can’t eat sweets. Prices keep going up and amenities and service keep dropping. Air travel has become more like taking a very expensive bus.

As a deaf person I appreciate the assistance provided by the boarding staff and the flight attendants.

WiFi did not work for the flight. Crew were polite but kept asking me to move my bag even after it had been moved to the preferred position previously and not moved since. I had a winter jacket as well and they changed their minds multiple times about where I was allowed to keep it.

Good seating and leg room. Able to choose seat. Nice crew, polite and helpful. Nice snacks. Meals have to be pre ordered, short flight do no meal required.

No complaints. Nothing for entertainment, but it's a regional smaller body aircraft, not a longer range long body. Didn't partake in any snacks, mainly slept for the whole short flight. Got me to A to B as intended.

I reserved exit row as I am 6’7” and was very disappointed to find out that my seats were as crammed together as the rest of the plane. Worse actually, as the seats don’t recline. I believe I paid an additional $200 apiece. What do I get for that? I guess it’s on me that I didn’t do the research to know this in advance but I’m tired of buying airfare which used to include an actual seat on the plane and now it is an additional charge. I think the seats I purchased are sold at a premium by deception by people like me that think these are desirable. Got forbid there’s an incident and passengers have to escape through these tiny passages. Love to travel but have to reconsider future trips because of the dishonesty of your industry. Have always had good experience in the past with Alaska but now I have soured. Thank you very little, Dean Jones.

Everything was fine, flight was on time. Seats are pretty comfortable. I paid extra for the extra leg room. Did not get food. The only thing I wish Alaska had was a seat back screen rather than trying to watch things on my phone.

The flight attendants stood there talking to each other instead of welcoming people on the flight.

My bag was gate checked in Seattle and I was told it would be at the end of the walkway when I arrived in Idaho. It was not and I had to get it from baggage claim. Southwest Airlines will gate check a bag even if they have room for it in the cabin. I like that a lot. Seattle Airport is not that easy to maneuver. Indianapolis is one of the easiest airports to navigate.

Room is great! Excellent value. Boarding & service extremely good. Food was the worst I’ve ever had on a plane.

The flight itself was ok but delayed take off meant that service was also delayed once in the air and it was a long time before the lights in the cabin were turned off. The food was pretty poor, which was disappointing for Virgin. Particularly breakfast which was a dry bagel with a pot of cream cheese. Economy sears were not comfortable despite us handing 3 seats between the two of us, I was unable to get comfortable and sleep. The entertainment was brilliant with a great selection and a very welcome addition was free high speed internet access for flying club members meaning I could stream video whilst in the air.

Food was okay. Seats were a bit cramped. In flight entertainment headphone socket didn't work on my seat. Wifi was great, so I was able to stream on my iPad

Selection of movies didn't include recent box office hits. Food was average not great. English sparkling wine is not drinkable. Otherwise, everything was great.

Check in at the desk was very slow pus Security, although not Virgin issue at JFK was a nightmare. 50 minuet wait no time to explore airport and get last minuet gifts. total wait 1.5hours

Great staff great experience, made a 2 hour delay very bearable

I was my pleasure to fly virgin on my birthday for my first solo trip ever 🫶🏼

Overall, flight was excellent but check in was very slow for Premium Economy. Economy queue was shorter but we weren't allowed to use it.

The crew was excellent as ever on Virgin. The special meal was poor unfortunately. More significantly when we arrived at Manchester Airport there was no air bridge provided and we had to exit the plane down a rickety stair case. This is unacceptable for a transatlantic flight. Whilst I understand that this is the airport’s fault at the end of the day the airline is responsible for our transportation and needs to do something.

Super friendly and helpful staff, from check-in desk to cabin crew.

i saved my points for more than 10 years in anticipation of treating myself to an upper class fight to and from london on virgin atlantic. i was shocked to find what you consider “upper class” on the dreamliner. it was, at best, a mediocre business class accommodation. it was tight and not that comfortable, with nearly no personal storage. everything was cramped and just generally disappointing. once i lucked into a 1st class upgrade to europe on lufthansa - a magical experience that found me reluctant to sleep, lest i deprive myself the joy of their setup. i expected something similar from virgin atlantic, but i could not have been more wrong. it will be the same arrangement on my flight home, but at least i know what (not) to expect. to be clear, this is only in reaction to the physical accommodations. your people were, and always are fantastic.

Meh. Lived the seat. The entertainment unit did not work and had to be reset 3 times. Service was SLOW taking over 90 min to be served. Crew forgot about my meal. Chicken was dry and almost inedible.

Flying on the Boeing 787 from Seattle to London was everything that I expected. Every thing was great.

Moved me away from my family and refused to fix it.

Connection at Hethrow was horrible..We couldn't get out of the plane for an hour as they were buying people to the airport and there were not enough busses. We had 2 and half hf between flights so it was very tight. After departing plane we had to go thru security again. People with less time in between connections missed their flights

Captain sick. Unable to get replacement so delayed me 30 hours, many others delayed 54 hours. TOTALLY DESTROYED ALL MY PLANS, including lost my rental car which would now cost over 5 times what I paid so stuck with buses n trains... lost hotel reservations.... HORRIBLE!!!

The BA business class cabin is excellent,very comfortable for sleeping but the service could be improved.

The flight from Seattle was delayed, which made me miss my connection to Florence. I was re-booked NINE HOURS LATER!!! That’s basically a vacation day lost. British Airways needs to partner with other airlines when possible to get a more realistic travel time, if delays occur. I realize there aren’t many flights to Florence from London, so I would book differently were I to return. The actual flight from Seattle was very comfortable and the crew was great, no faults there. I enjoy British Airways, this was an anomaly.

Could have done with a 2nd round of drinks even if it was only to distribute bottled water

The second leg of my flight unexpectedly got canceled. I was stuck at the airport for the whole day and instead of flying out that morning I flew out in the evening. For some of my fellow passengers it was the second cancellation and their original flight was supposed to go out the day before. There was no reason given though getting rebooked was quick even though I would have preferred if I would have been on one of the earlier flights that day. Compensation was a £10 voucher for some food at the airport. I eventually arrived without further incident but but due to the cancellation, it was one of my more frustrating travels of my life.

Due to a cyber attack at the SeaTac airport ALL of the airport computers at the airport were down. This seriously impacted every airline at the airport and the resulted in our flight leaving a hour later than scheduled. This delay caused us to miss our connecting flight from Heathrow to Edinburgh. I was amazed to have British Airways staff meet us at the gate as we left our flight. They quickly provided us with new boarding passes for a flight going to Edinburgh later the same day. Problems sometimes happen but they handled the situation in first class style.
