Airline reviews

All went fine. Boarding was efficient, staff was really friendly, and we were kept up to date on any changes to our itinerary. My only note for improvement is that on this particular plane, the recline in economy class was negligible. I know it's a coach seat, but I had another UA flight (SFO to BWI) and the seat was more comfortable with better recline.

Really good experience with a redeye flight from SFO to BWI. Boarding was efficient, plane was comfortable and newer than others, lots of audio and video choices, and staff was great. I appreciate United's service.

United airline kept delaying our flight back to Phoenix for 8 hours before they cancelled it! If they know that we are not flying out for whatever the reason is, why did they keep lying to us for hours. We could find another flight earlier or even find a hotel with a shuttle. But cancellation at about midnight was not fun. We stayed in the airport all night till the following morning when we bought an Alaska tickets to go back to Phoenix. Total of 14 hours in the airport.

Poor seating comfort, seat cushion too thin, very uncomfortable. My luggage didi not make the flight due to equipment change. At least. United had it delivered the next day. I was without my toilet items for one day.

My experience is based on one crew member. I had found my seat and sat down but there was a gentleman to claimed to the flight attendant I was in his seat. She then came to me and curtly said, "I need your ticket!" No hi, no excuse me may I see your boarding pass? NOTHING! I was taken aback by her attitude and she repeated herself, "your ticket?!?!" I calmly responded with ok, here you go. Only to discover the gentleman was looking at the wrong boarding pass. She gave me back my ticket with no apology. She then was curt with another man who was putting his coat in the overhead bin, already helped by another flight attendant who said it was fine. She realizes it's ok and then asks him if he drinks. The look on the man's face was priceless. She said she was going to comp him drinks. He gets offered a comp drink for a coat as well as an apology, and I got no apology.

Liked Seat space in Premium Plus Disliked delay, poor management of boarding groups, missed meal at landing.

Flight cancelled because of the grounded 737s. United was good about it and got us onto a later Alaska Airlines flight to Oakland (not San Francisco as originally intended). Had to go through security again and my wife dropped her MacBook Pro, which broke, a $2,500 whoopsie. But we made it home.

temperature, temperature, temperature. it was hot as balls and everyone around me was complaining and constantly adjusting their vents

Delays, excuses, delays, and more delays. This company is BROKEN.

Horrible. Delayed on both planes several times. No attempt to fix it

I can say I will not be taking this airline again any time soon. Seat were uncomfortable and too tight. Lack of chair screen and little overhead space.

American Airlines canceled the flight twice and was unable to facilitate a change of city for us after our travel plans became affected. We lost alot of money due to this and it seems like the airline was trying their best not to facilitate this. Mind you, I am a very loyal member.

Plane felt so crowded and tightly packed. The chair itself was not comfortable.

They attended to my needs as I couldn't walk and they provided a wheelchair for me.q

Poor availability of food. Cold cabin temperature. Extremely long waiting time for a flight attendant to respond to a call button signal.

2.5h delay due to unruly passenger in first class. Had to be removed from the flight. No food unless pre ordered. Didn't know we would need it because of delay.

This time my flight was smooth and uneventful. They started boarding even earlier than it was scheduled. I was pleasantly surprised. Thank you!

Only my carry that was taken and found it in my final destination

The flight landed at LAX we were then bussed to collect our bags. That process took nearly as long as the flight. Luckily we weren't in a hurry!

We had a humorous and kind flight attendant, boarding was efficient, flight smooth, pilot gave updates and was humorous too, two drink services was very helpful. In flight entertainment is always appreciated

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

Crew was rowdy and loud just hanging out in the rear of the plane instead of assisting passengers during boarding. During the flight the crew mostly hung out in the rear of the plane being obnoxious to a point of disturbance.

United flight from Frankfurt to Istanbul is on Lufthanza and United could neither provide a boarding pass or Lufthanza code to get a boarding pass. Very poor connection ability in Frankfurt and much frustration with the connection.

Need more time for connecting flights in Munich Food seems worse now on Lufthansa Very uncomfortable seats

Good with last minute upgrade Clt to Munich comfortable. Wish same offer had been there Mumbai to Munich

Excellent service by united air staff. Very helpful, understanding and do friendly.

+ Clean, modern plane. - Despite the cabin had only 50% occupancy I was cramped in a row with 2 other people. Almost all other rows had only 1 person. I would have expected the airline to offer assistance other than a flight attendant to tell people in the back of the plane to find available seats. Next time I will not purchase an upgraded seat and hope I get my personal row for free.

Overall experience is good with boarding and food. There was no entertainment provided on a leg that made it bit harder.

Better flight than mum to Frankfurt. But food was very mediocre.

Got auestioned multiple times by gate agents. They ran out of chicken for the first meal. Slept pretty good on it and had good entertainment.

Very bad, never get this flight again and crew was worst and are rude especially one bald guy was not helpful and there was an other German guy who was bit helpful. Lufthansa owners should look into this matter seriously and food was not good as well

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

I was rebooked on Delta. Did not take this flight

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.

Everything was fine except my screen wasn’t working and I was unable to watch any movies or TV. Staff tried 3 times to reboot it, without success.

Boarding ,checking in was easy and quick . Comfort was not good.

It was good… always SO many people… I realize that’s how they make money but wow!

Positive boarding experience, easy access to seat with plenty of luggage space

Undocumented cargo processung delayed flight 1 hour. After getting all the way out to take off, we had to go back to gate for 45 min + processing & refueling. :(

Truly felt "taken care of". Will definitely fly British Airways again.
