Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

One of the best flying experiences I’ve ever had.

737 Max was leaking water into the cabin through the windows. Overhead bins opened on landing. Bad bad plane.

Unfortunately this is not a happy ending comment. Positive: flown United before no issue Negative: it only takes one bad experience to not plan future travel with United Cancún departure was delayed by 1h20 minutes, connection in Chicago was 1h30 minutes. Flight departure time 6:08 Miraculously 7 of us ran 4 kilometres through Chicago to arrive at 6:00 to be told very rudely by the 2 unprofessional United attendants you missed your flight and that we should of arrived early. Did I mention that reason I was flying? I received a call that my brother was dying and to get home. They provided no assistance would not answer any of our questions, ignorantly walked away. Deplorable

I was not able to buy food in the flight. They refer to include your Credit card in the APP, and if you are not from USA (i have a credit card form Canada) it is not possible

This flight was a code share on Air New Zealand.

The plane boarded and deplaned twice before the crew timed out. Flight was 7 hours late departing. Horrible experience!

Boarding process was well organized and orderly even though flight was fairly full. Water bottles were provided during boarding which was great as I drink a lot of water. Bathroom was not as clean as it could have been but was acceptable and fairly dry. Food however was mediocre. I have had better food on 2 hour local flights in other countries.

Over two hours wait to get wheelchair assistance from arrival to the departure gate for LA was unreasonable even though there appreared to be heavy demand.

The overall ambiance was good. Seating ain the last row not so pleasant.

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

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.

Always find Aer Lingus reliable and good value for money. Food on this flight was pretty basic and the headphone Jack at my seat only worked for one ear. Little disappointed in movie selection, limited on recent releases. Staff are okay - but I always buy a cheap ticket so not like I expect first class opulence anyway!!!

Boarding was so quick, flight was ahead of time which is great and the pilot spoke clearly and was letting people know everything, amazing, love travelling with you 😊

Great hospitality and service! Seats are better cushioned then some

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

Excellent long haul experience really enjoyed using Dublin pre-immigration

Nice easy flight. Crew was very nice and of all the times I have bought a seat for my guitar - this was the easiest. They were prepared and no problems at all.

Air Lingus flights were delayed on each of the three flights we took. Not a very good , and organized airline.

Flight was ontime, clean, staff was friendly - there was turbulence but can’t avoid that (it’s a flight 😉)! The staff were attentive but would be nice if Aerlingus didn’t charge for coffee ☺️ but overall I enjoyed my flight experience and will travel with them again (Ireland’s Four star airline

So Iceland Air is one step above Spirit Airlines. They do not feed you unless you pay for it or are in Saga Class. So, bring your food. They have a drink service, but it's in a large Dixie cup. Ask for the can, that is the only way you'll get a real drink. Also, we missed our connecting flight so they put us up in a flea-bag motel. Don't get me wrong, the staff was nice and friendly, however, there was no shower gel or shampoo in the hotel. We have to go to the corner store to pick some up. The room was not in great shape. Holes in the bathroom, a badly repaired ceiling in the room. The window was warn out. So, you get the just of how bad it was.

Food and staff were excellent. Seats on Saga (business class) are comparable to domestic first class of US Airlines, regarding space and recline. Entertainment options had little international component.

Flight delayed Delay to the gate upon arrival Baggage took more than an hour so we missed our connecting!!! Terrible experience!

There is no food without paying $. Only soft drinks are included in your fare.

Some drinks and basic snack will be good. Water should be served at least once an hour. Blankets for folks who might be cold.

Pros: "Flight was relatively empty. Professional crew, comfortable seats"
Cons: "I think they skipped me with food service. Checking up on passengers who may have been sleeping would be nice. Headphones need to be purchased. Limited entertainment options."
Cons: "Communication about international COVID requirements before the day of departure."
Pros: "My seat cushion was out of alignment so not great. But I like the two side seat configuration."
Cons: "Boarding is a zoo. Board by row. It’s faster."
Pros: "Icelandair crew were very hospitable and accompodating"
Cons: "I have never sat in such a narrow seat. Literally could not put my hand down the side to pull out my seat belt. Two days later I still have sores from where the side of the seats hit my hips. Did not even provide complimentary peanuts."
Cons: "Took far too long for drinks service into the flight. Almost 2 hours in before drinks came around to me"

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

American was good / British Airways partner was not as good…

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

A little more legroom, and maybe a little bit of food

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
