Finnair cancelled my flight 12 hours prior to leaving for Helsinki. They stated there were mechanical problems. I had to scurry around to find a new flight that would meet my needs for arrival in Helsinki. Luckily I was able to find alternate transportation through Lufthansa/United.

I’m very disappointed, to fly into an airplane for 10 straight hours, and not having a TV even though when I put the ticket I was told that I will have entertainment for the TV. Very disappointed.

Helpful steward. Allowed me to move to some empty seats and I was able to get some sleep. He also had milk for my tea. Americans don’t realise that cream or half and half ruin tea.

Security was a mess at the Helsinki Airport. But I was delighted by the connecting flight waiting for us for JFK.

The crew was very good, excellent, they help me with my needs.! Food was not that good.

Everything was quite easy from boarding to landing - the staff was great and service was excellent too!

Flights are standard. But being over 3 hours late is too much.

In-flight entertainment was. It working for the entire 12 hour flight! Unbelievable! At least provide free wi-fi so people could use their phones.

The flight was surprisingly good, especially given initial experience. BA app is horrible as is their customer service. Online check in was a horrendous experience and when I phoned their customer service number, the live agent with whom I spoke was rude and dismissive. She did helpfully inform me that their IT people were working on a known problem related to online checkin. However, once she delivered that information, she curtly ended the call before I could suggest that since BA was aware of this, it should be posted on the app and online. I grudgingly flew BA this time - have avoided them for years because of past similar serial bad experiences. While this flight was fine, I’ll return to avoiding them in the future given the hassle experienced and rude personnel.

Boarding was a shambles, with no proper line or queue and multiple groups joining at the same time. Overhead space was limited. Seat spacing (width) is not generous. My neighbour was invading my space, before he even spilt his drinks over me (twice!) as he struggled to contain his meal on the table. The main meal was very poor. Choice was simply chicken / turkey - the crew didn't know exactly which - or vegetarian. The chicken meal was really poor quality - uninspiring and tasteless; and very little offering of drinks. Half the crew were friendly, half really need to cheer up.

Flight was delayed 3 hours. Pilot cancelled flight under 4 people volunteered to change their seats to economy from business class.

I paid for wifi and it worked about a total of 5 min. Feel ripped off

Overall, this flight team did a fantastic job. They came often with the water, coffee and tea. There was no meal choice in coach, but the lasagna lunch was decent. The sandwich snack just before landing was tasty. The baggage bins were large, so no trouble holding carry on luggage.

Good friendly service and food - The seats in business class are old, too hard and not very comfortable.

Old plane with terrible business class seats - good food and service. Boarding was a joke with business class boarding last.

Best airline to travel on a budget- really like their reasonably priced access to the SAS lounges where available.

Flight was delayed slightly but was very smooth. It was a short flight but comfortable.

I child in Buisness cried almost the entire flight. And I had a conference to attend but couldn’t sleep because of that, which was the main reason for getting a Buisness ticket. Also the food is not as good as before. The sheets underneath is also not there anymore. The staff was nice.

little entertainment choices. Seat/bed too firm an no sleeping mat

Little space and no pad provide for lie flat seats in business, Movies were limited and grouping very strange.

The only problem experienced was a ground stop in Chicago due to weather. But the crew handled everything professionally. They prioritized rebooking those passengers who had connecting flights and then deplaning the other passengers. When the hold was lifted, they efficiently re-boarded all the passengers so that we could depart before our departure limit expired.

lounge was the highlight - seats weren't that comfortable - it was a full flight but no complaints

Our second leg to Jackson WY was unable to land due to weather. We were flown back to Dallas after stopping in SLC. We were given hotel rooms and vouchers. We were told that we would be back on the same plane in the morning. Instead we were given a different flight with different seats. Not a good experience. No one knew what was going on.

Turn on the heat. Flight was way too cold from Arizona to Chicago.

Perfect flight. On time departure and early arrival. Smooth flight.

Overall pleasant was delayed and caused transportation issue when landing

The arriving flight was a few minutes late, but the gate crew helped to deplane and board our outgoing flight quickly and efficiently. We were able to depart quickly and arrive at ORD almost at the posted time. Great job.

Nothing, flight was supposed to leave at 758 am. My flight didn’t leave until 430 pm. Spent the whole day at the airport.

Despite a bumpy flight the pilot was great. The rest of the crew on the other hand couldn’t care less if a passenger would colapse and die. Horrible service, robot like, lifeless…

Biggest issue was original flight canceled and booked to another flight 6 hours earlier and received no notification

There were a lot of empty rows. As a single passenger I should not have been seated with 2 others. The WiFi didn’t work. The Kosher meal was awful.

They should. Heck planes more often not when they are suppose to be leaving causing delays

Thankfully not a full flight so although my headphone jack wasn’t working 100% on my window seat, I was able to move to the aisle seat. Food was fine, nothing great but tasty enough. Crew were friendly and made enough rounds. Always have a decent experience with Aer Lingus

Crew was fantastic got lovely food and plenty of water. Entertainment was good. Never had to ask for anything. Left on time and got to Seattle early. Luggage did not take long either.

Great hospitality and service! Seats are better cushioned then some

Great hospitality and service! Seats could always be cushioned better.

Customs is always a challenge. The customs officials were real humans, which was nice-not robots programmed on angry 😊. If you’re in a hurry to get through you’ll be stressed out. Allow yourselves plenty of time and it will be a stress free experience.

I got rerouted to another flight/city because the original flight was late and I would not have made my connection. I had to wait an additional five hours (no compensation) for the new flight which was also delayed because the computer was not working. Arrived at my final destination after nearly 20 hours of travel only to discover that my baggage had not arrived with me. Two days later and still waiting for my baggage. Customer service has been incredibly unhelpful and even hung up on me because I dared to ask for them to have someone call me when my bag arrived at the airport. No one apologized to me for what I experienced and they were dismissive of the fact that I have absolutely no clothes or toiletries. Absolutely awful, disorganized and stressful experience. Am dreading the return flight.

As four hour wait with no explanation as to why the delay Very unacceptable

Excellent long haul experience really enjoyed using Dublin pre-immigration

The crew on this flight were excellent. They were friendly and attentive. It really made the flight more enjoyable.

I sat in the last row of seats. On an 8 hour flight they allowed folks to stand and talk and drink in the back area near the toilets the whole time. They were at times loud and in the way. It was a little annoying. The crew on this trip were pretty mediocre and the plane was littered with trash when we disembarked.

Boarding process needs to be improved. Business class passengers were told to stand in the economy line and vice versa.

I travelled on biz class and f there is no water in the toilette to wash my hands I would expect to have this indicated somehow and not just finding out when I'm there expecting to be able to wash my hands and teeth. Also this is in general that it is always so rushy at the end of these kind of long flights. It is like we are sitting there for 9 hours and the last 1.5 hours just feels like I have time for nothing. Because food comes and at the same time we are close to destination everyone tries to pack their stuff and go to toilette and eat and everything :))) not that like I would know a good solution here I just wanted to raise this :)

Emergency row seat less comfortable than promoted. Restricted by emergency life raft storage.

Better communication to those connecting flights and have a customer care desk at the airports

The entertainment system in our row was not working. That makes for a VERY long flight!!

Pre flight food options were not working and made the flight not enjoyable. Post experiences of British airways have been positive, but this is enough to stop me using British airways again

Flight cancelled and i was rebooked on delta. Delta business class is not the same as British

Boarding could be smoother. But the flight crew was excellence. Very professional, friendly and helpful.
