Not worth the premium paid for the first class ticket

Not worth the premium paid for the first class ticket

Not worth the price of premium class ticket paid, felt more like steerage.

Flighty delayed on boarding - then group 1 had to check their carry on bags but groups 3 and beyond could carry bags on - very inconvenient for weekend business trip with no checked baggage. Then delayed on the runway - before take off. No communication from pilot on why or how long. Wifi/Entertainment didn't work for 4+ flight. Upon arrival, attendants announced wrong carousel for baggage claim - everyone was waiting at the wrong place for their checked bags. This was a mess united!

I flew Delta last week and United Airlines is a poor substitute mechanical problems with the plane and shitty food among other things made my travel experience what’s become to be expected from United no way is it ever worth the money they make us pay

I had a great flight. Everything went smoothly and the flight arrived early.

Well....let's start from the point that I had to stay in airport for 12 hours instead of 2 that was scheduled. Poor company and even worst customer service. Never again....

The flight and boarding were easy peasy. I was traveling with my 4-year-old, so a smooth boarding experience was especially appreciated. My only piece of feedback is really about where our gate was in O'Hare. They've shoved four gates into a tiny corner of the B terminal and there isn't early enough room or seating for everyone. Not United's problem, but did dent the overall experience.

We liked the fully reclinable seats. Had center seats, so it was difficult to talk to spouse. Crew was great

Aisle chair was good and liked the foot bar preventing you from putting your foot in the isle, The breakfast on this international flight to Zurich was horrible (Europeans, specially, used to good food) may make this a dealbreaker for booking with United Airlines again. I agreed with my Spanish fellow passenger.

Dinner was okay but the breakfast was not eatable on the flight San Francisco to Zurich.

They cancelled two flight and got us onto another airline, which was also delayed.

Nothing, terrible travel experience due to weather and maintenance delays and was left stranded in Austin.

Missed connection from Philadelphia to London because flight from DC was seriously delayed. Was re-routed the next day (had to pay for hotel) to Zurich and was given a main cabin middle seat while I had paid for premium. Great job AA!!!

My husband and I pre-ordered our food, but they did not have my husband’s order, and my cheese plate was very average. I asked for a blanket and was told they don’t carry blankets on domestic routs. The flight was on time and smooth!

28 hour delay at Fort Worth/Dallas airport, part due to weather which was unavoidable, but various other reasons - no pilot, no fa, mechanical problem, plane too small, too big, crew out of flying time, seat configuration problems.... endless and hourly updates with a different excuse. Finally told us about 3.00 am, that the flight was delayed to hours later.

Experience was bad. 3.5 hour delay for a 2.5 hour trip. There was no r Transparency about the reason for the delay and it was done 30 mins at a time.

Original flight delayed several times and finally canceled at 2:30 in the morning. Staff at the gate was not very helpful in resolving problems or communicating why there were delays. I spent 34 hours at the airport before I could leave, they couldn't book me on another early flight even after canceling my original flight. Next flight available after my original flight was canceled was 22 hours later. I will never fly American Airlines again.

very very tight seats unfriendly crew who do not seem to care about the comfort of their passengers and do not know how to smile poor ground staff support at LHR and PHX

The boarding process and flight were great. However, I waited about 40 minutes for my luggage. It did not come up on the designated belt. Instead, everyone’s bags were on a cart. Not sure what the issue was, but we were not informed until another passenger went looking for her bags and found them.

There were delays on both ends. It made it less than excellent. This plane was great though

My flight was cancelled after a 7 hour delay. I am awaiting a refund.

Disappointing. Had to pay 70 euros for one checked bag. Transatlantic flight was cramped, not very comfortable

Ability to select seating would be nice. We were family of three and they had us seated back to back and one of us on the other side of the plane??? That is pretty goofy. Especially when tickets were placed two months in advance.

Pretty fair for the price of the plane ticket. Food was poorly, but overall was a ok experience for a super long flight.

Good. Madrid to SFO was way better than ARN to Madrid. Mercifully, the seats to Madrid didn't recline. So although there was no leg room, your knees didn't get crushed

Overall was good except for the seat which, for an 8 hour intercontinental flight, was uncorfortable. For that kind of flight seats should have more space, even for economy seats.

Needed more info on connecting flight. Late flight made very short connection. Lost luggage that we still do not have!

Seats comfortable on economy plus and attendants very helpful. Food was ok. Bathrooms needed servicing.

Good food, prompt and timely flight, good on-board personnel

Thankful for 2-4-2 economy seating. Food was ok. Free beer & wine in economy was nice. Served hot dinner, mud- flight snack and pre-arrival ham sandwich. Seat with pillow & blanket. Reasonable movie options. Overall, a good experience. IBERIA APP is terrible terrible terrible.... needs to get upgraded to equivalent of TAP Airlines App. No option to bid or request an upgrade. Very disappointing.

The flight crew was extremely accommodating, finding a place for my guitar. Thank you so much! Departure time, however it was delayed almost an hour because the plane was not at our gate on time. We did make up most of that timing flight, however, but it is always annoying to be delayed for that length of time. I was looking forward to the, but, honestly, it was really bad. Overall, however, my first experience with Canada was really good and I would recommend you. Thx.

No meal. Flight crew was wonderful, happily finding me storage for my guitar. THANK YOU!!!

My seat was moved multiple times. I picked out the perfect seats beforehand. I even paid extra money for them. However, I was moved to a middle seat without warning at the last minute. It was like my worst nightmare. But other than that, the actual flight was good. Everything was on time or even early and the flight was smooth.

A220 plane had 5 seats across which is great for couples who can snag the A&C seats. Seat itself is borderline comfortable but still tough on a 5+ hour flight. Overhead bins are small so if you're not in at least boarding group 5, you could be in trouble. No included food service. Non-alcoholic drinks are free but even the most basic snacks are for a charge. Price was reasonable for the only direct SEA-YUL flight. Boarding is efficient even managing passport checks. Worth flying for the direct flight.

The original flight from Boston to Toronto was canceled because of a mechanical failure. I was then scheduled on a flight to go from Boston to Montreal and then Montreal to Toronto. The flight was extremely full and I had to check my carry-on bag. When I actually got on the plane there appeared to be room for my bag. I understand the mechanical failures happen. But it was frustrating that they pestered me to check my bag when I don't believe it was necessary. Additionally, not just with Air Canada, modern airline seats are incredibly uncomfortable. There is considerable research that shows that the shape of them is poor for back health.

Unable to initiate refund/reschedule the ticket #worst experience #lost 900$

Flight was delayed for almost 3 hours. Communication of gate change was poor. Email and screen said one gate and it was a different gate from that. Gate changed first to 64 B and then to 64 C. Originally it was 68B. 64C was not communicated properly!

This was a red eye return, so I doubt there would be anyway to make it better. Other than adding beds.

Direct nonstop flight was great. Flight was delayed and the crew announced a 2h delay on the sound system. 30 min or so later I hear my name on the sound system for immediate board. Several other passangers were late too. Reason: The crew incorrectly announced a 2h delay when in reality they meant a new boarding time at 2pm.

Plenty of room in the exit row. Sat on the plane an hour before taking off.☹️ Landed late and had to wait for gate availability.

Boarding was as fast and efficient as possible. The flight crew were amazing and extremely friendly. We enjoyed our flight.

Very bed boarding, there was overbooked and make a lot of problems and noises

There was a problem in the luggage because there were not porters

On my way from Chicago to London, I was seated next to a quite heavy passenger. I could barely move. BA should have ensured that overweight customers are placed in comfortable seats and not to penalize also other passengers because BA is not willing to accommodate these passengers and their needs. No respect at all.

The flight as far as timings go was excellent. Unfortunately we ended up sat with someone on a night flight who had been drinking alcohol before boarding and BA staff were happily serving him more alcohol. He was very drunk which made our flight uncomfortable and awkward. My partner had this person lying on him whilst asleep. Alcohol should be served minimally. If there had been an emergency this person would not have been in a fit state to act accordingly.

First time flying with BA and I will do it again. Staff at airport and on board were very nice and helpful

they are improving. The crew from Charlotte to Tampa was outstanding. SMILING and trying to be helpful with the customers.

Wonderful service and very comfy in the bulkhead in Economy Plus! Delicious food.

The BA team at Sky Harbor is deplorable, full of unnecessary attitude and poor communication. It seems like every member of the team was looking at another to solve the problem, instead of taking agency to do so themselves. I saw no less than 6 altercations with the same gate agent where he threatened to revoke the passengers boarding pass for asking a wildly reasonable question, something as simple as where the cue to board was. I’ve complained to BA before but it seems this isn’t an issue for them, which is very disappointing

Boarding poor in London,ok in Chicago. Don’t like Heatrow/terminal5
