Friendly flight attendants. Comfort plus seats were very comfortable and had lots of leg room. 10A and 10 B.

I've flown many many times on Northwest and then Delta. The crew on this flight were absolutely the best I've had the pleasure of being looked after by.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Awful. Flight was continuously getting delayed and gates kept changing without any reason. Flight was delayed for more then 3 hours

Paid premium for Delta only to be on safe but tired old 767 with ancient cabin in mediocre condition. Poor wifi and horrible inflight entertainment. Hardly a premium experience. Should have flown SW and had fun flight crew and no pretense

Our flight to Zurich was delayed by almost 3 hours, so we missed our next flight. There was no indication it would be delayed this much. We were told the gate had changed and then it apparently took over 2 hours to load the "catering" on the plane. We were not compensated in any way for the trouble.

Rated entertainment as Mediocre as there were major problems with the Infotainment system that took probably a half hour for them to fix.

Your crew could maybe answer the call bell at least one of the times I pressed it. I pressed it first time with 2.5 hours left in our flight bc my partner was hungry and wanted a sandwich. We finally got the sandwich with 40 mins left in the flight.

Half the bathrooms assigned to economy were out of action

Cabin crew on our flight showed lack of any customer service gruff and acting annoyed if you asked anything and I mean anything Example a man on the seat over dropped his beer on my husbands blanket We asked if we could switch out blankets cabin crew Said. No we don’t have any extras OK well can you take the wet one Cabin crew looked disgusted and annoyed Took it no OK or yes just a growl

Quick flight. But cabin crew were very noisy and talking too much, especially when we were seated at the back of the plane trying to sleep through the night .

My ticket was for Premium Economy and all the seats were taken, I was placed in Economy class and I’m looking for a refund.

Unfortunately delayed 2 hrs due to faulty tyre.. which had to be changed, but better safe than sorry.

The delay was an issue. Other than that. Every thing good

Hi vergin Atlantic service was good but the flight ticket agent travel up charge me extra 57 pounds as a airport charges, actually I refuse to pay but they say if I not pay £57 then they say you will not be able to travel from Heathrow to goa ,so for me there was no option and it was just 3 day before my departure so i paid, so please look in to the matter. And I have a receipt of £ 57 as well .thanks

Staff didn’t check cabin well for landing seemed more interested in chatting to each other. Food was poor and differed from pre order.

We were in the last group to be called to the flight - which was 30 minutes late taking off. While we were lucky enough to have been given bulkhead seats (due to a medical condition I’d told them about beforehand) the seats weren’t particularly comfortable. A crying baby for the whole trip made things worse, so the crew managed very well with coping. The final thing I’d say was that there wasn’t enough food served during the flight.

Very good. Glad we had Premium for the flight out.

We flew Upper Class from London to The Turks and Caicos. Check in was amazing. Our ldriver too us directly to a special entrance to terminal 3. It took 10 minutes to check in and clear customs. Amazing! The VA lounge is large and comfortable. Boarding the flight was easy and without a wait. The crew was excellent. But the seats were awful, strange and uncomfortable. Having a comfortable flat bed seat is the reason we pays 1000s extra. The VA 787 uses a reverse herringbone configuration. Look it up. You have your back to the window and are facing the aisle with no privacy. Turning the seat into a bed requires assistance from the crew so not very spontaneous. . The food was ok. A bit tasteless and meager portions. Had to pay for WiFi. I believe VA has other configuration on their dream airbus flights. Lots of stuff about all this on YouTube where you can see what I have been describing. I can not recommend taking VA on a long flight with these seats.

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!!!

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

So uncomfortable to sit in the tiny space on a long, international. Food was rough. Please, less white flour and processed food.

Worst experience flying American Airlines. I fly with them often, so I was super disappointed in the service I received at gate 30 in LGA on May 24, mid-day. The flight was delayed twice. I was patiently waiting in the American Airlines lounge when I received the notice on my app that the plane was boarding 45 minutes before its newly re-scheduled take off of 4 pm (from the orginal 1:45 pm then 3:00 pm). It took me 5 min to travel from the lounge to the gate and when I arrived there at 3:20 flight gate attendant told me the flight had closed and that they announced for passengers multiple times. I showed them the notification on my app and they were really rude and unempathetic. The person who rescheduled my flight at customer service wasn't any happier but was at least helpful in getting me on the next flight.

Our flight was delayed 2.5 hrs due to plane being too hot! After 1.5 hrs, airline decided to use another plane but had to wait for gate, baggage transfer & beverage transfer. Anyone could tell after first half hour that another plane was required and although did not affect us many would miss connecting flights at Heathrow. I have found the stewards are not the friendliest in the industry and the food is questionable, even as I like airplane food normally, the best of the 2 flights was the yogurt & granola for breakfast.

Terrible boarding , Business class seats are sub standard. As usual crew will miss your food too

Just get Economy Plus for international flights, so worth it the extra room, bigger seats…

The return trip was a customer service disaster. American Airlines needs an overhaul of how they treat their customers.

Was flying in premium eco and there were around 5-6 movies I wanted to watch and none of those could I play for some reasons. Not just me we checked w the person sitting next to me. Few of the movies were only playable :( Also that was not great that we couldn't upgrade to business however tried to, many times before the flight :(

We left our child’s tablet on our seat 12 B on the plane and we can’t get a hold of anyone to try to get help locating the tablet.

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

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.

It was not Iberia. It was with United. It was great!!!

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

I am quite satisfied. The flight was on time and landed early. Staff was friendly.

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.

Original flight was cancelled - After waiting 2 hours for new take-off times. Then had to stand in line for 3 hours, ending at 2:30 am - to be told, " No hotel rooms anywhere in Dallas". No way for me to get any rest at DFW at that time of night.

I liked the friendly crew and desk staff, all very helpful. I was surprised and a little annoyed on my outbound flight from LGW to MCO as I had prepaid and booked my seat, which was all correct at check in on my boarding pass. when I got on the plane someone was in my seat ! I was moved to another seat. The food choice is quite limited and I feel that an option of a muffin for breakfast snack would be welcomed, not everyone wants egg or bacon wrap. The choice of entertainment is good, plenty to keep you busy on a long haul flight. I liked the option offered to have the cabin bag checked into the hold, it saved me as an older, lone traveller lifting my case into the overhead locker or finding there was no space.

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

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

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

It was very good. We got a late start by about an hour and a half. However I worked rather have that than crash. It was purely mechanical. They had our tickets ready when we came off the plane in London for the next leg. The only mishap was when we got to Lisbon my husbands luggage made or bit mine didn't. All was not lost because I did finally get it 2 days later. I was really pleased that they c made the effort.

Liked that my American Airlines status seamlessly transferred to BA so luggage check was free. Flights were on time, boarding quick. Wish they didn’t assign connecting gate so late at Heathrow.

The entire process was flawless and as expected flying first class. The only thing that I have a complaint on...when first boarding, the plane was EXTREMELY cold; then when we were trying to sleep, it was way too hot - just better regulating (especially trying to sleep) would have made it perfect.
