On time every leg of the journey and exceptional staff at counter, gate, and on board. I haven’t travelled in US for a long time and was genuinely surprised how pleasant this was.

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

Trip was smooth bumpy from the wind but no issues at all the crew attendant was very pleasant and had great customer service

I liked everything about the flight. The service was excellent!

The customer service was excellent! Check-in, baggage check-in, boarding, the flight went very smooth.

Delayed a day due to snow storm. Was upgraded. That kind of made up for significant delays from FLL to COS with no compensation or acknowledgement.

The Polaris experience is top notch. From departure lounge to arrival lounge. Everything was top notch. One of the best first class experience

The leg space between me and the seat in front of me was excellent.

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.

Crew is way too many times on the intercom re explaining the same thing

Missed the flight because of them and up geting a rental car

Flight was fine. It took an unusually long time to have baggage delivered to the carousel in ORD.

I arrived to the airport 2 hours before my American Airlines flight was scheduled to take off. I have TSA pre-check. The airport was crazy packed when I arrived. After momentarily standing in the pre-check line, the TSA agent said that I am not pre-check. Of course I said that I am because I entered my KTN number on all my traveling sites and programs. I had to get out of line and go back to the AA counter to discover that American Airlines did not add my KTN to my boarding pass. I had to call TSA to find out my number, then have AA enter it onto my boarding pass. The emblem would not load onto my boarding pass. By this time, I decided to use my Clear in order to get through TSA but the line was ridiculous long. By the time I made through TSA, I missed my 11:08am flight and was re-booked for the 5:30pm. This is after the AA employee told me I should have gotten to the airport early. AA use to be a dependable airline not I use them only if I have too.

Flight from SBP to DFW 1. They rerouted us through PHX 2. Delayed flight out of SBP for 3 hrs so we missed our connection Downgrade on rerouted flight. Back of the plane, center seats, didn't sit together 4. Return flight out of DFW same exact thing. Delayed, missed connection, Downgrade + they lost our luggage! A complete mess.

Do not eat the bagel! Otherwise, good albeit late, breakfast in first. Boarding downgrade only because flight was delayed due to plane change due to undisclosed problem with original aircraft. I did not use entertainment.

Was as expected. Good leg room on planes - much appreciated.

Fight crew was not very attentive and the bastions were gross!

I don’t think the flight attendants are happy. They do not seem to be friendly or welcoming.

Gossipy flight attendants talked the whole flight about bar hopping and dating.

Didn't like the 6 hour delay as it caused me to miss all of my connections. Still, I did get home safely 14 hours late but exhausted.

Horrible experience. Nothing to give to kids to keep them entertained.

I think I have bruises on my kneecaps. Do the seats have to be so close together these days? And if they are so close they really shouldn’t recline. I think when the gentleman in front of me reclined, the back of his head was on my chin. That being said the crew were always caring and polite, and the flight was on time and very safe. So I’m grateful for that.

I dropped my wallet under my seat on this flight with all of my money and credit card. I requested to be able to go back and retrieve it but Lufthansa denied my request. I went to the Customer Services and they called Lost and Found but I was told nothing found would be turned in until around 12:00pm. My next flight was leaving so I was unable to check to see if my wallet was turned in. I will never fly with Lufthansa again.

My concern is with Flight: 441 IAH-FRA I was very cramped in my seat and the person in front of me was reclined. I pulled my wallet out of my purse and when finished I did my best to cram it back into my purse. Our flight was very delayed and we were rebooked twice and lots of airport time. As I got off the flight I noticed that I had dropped my wallet( containing all my credit & debit bank cards + 240 US dollars & 240 Euros. I spoke to customer service & Lost &Found. I was denied access to look on the plane. Therefore I have been without money and given no help. Paula Bjork 503.545.6698

Overall good experience. Polite crew. Good foodandentertainment. Seats are small and bit congested though.

I ended up buying (for $340) "extra space" seats because I my flying partner was given a STY boarding pass, leading me to conclude that she was on standby and that we had to buy seats on the flight. I later learned that the flight was not sold out and that we could have gotten on as usual. To be honest, I felt swindled.

I'm Canadian. I have the unfortunate experience of pretty not having the choice to fly with them. THEY ARE TERRIBLE.

The process overall was pretty seamless, and the crew were very friendly (especially Michael). Considering we booked expecting Lufthansa and the flight was operated by United, it was still a very good service and journey overall. The in-flight entertainment was great, with lots of quality options. One slight negative was that I had selected a vegetarian meal prior to flying, but received a vegan one. I think there should be more dietary options as it meant I missed out on some food that I would have preferred (and it seemed like the standard meals and snacks had a vegetarian option anyway). There was also a group of people who were moving around a lot and being generally disruptive at the quietest part of the flight, when the lights were off and most people were sleeping. I would have appreciated staff stepping in to encourage them to be mindful of others). Towards the end of the flight (which was very early in the morning in both time zones), the lights suddenly came on and breakfast was served. In my opinion, this was too early, and everyone was rudely awoken from sleep. After breakfast was cleared away, the lights went off again for about 45 minutes, allowing people to sleep some more. Then the lights came on again for landing. It seems like if they had served breakfast later, the lights on-lights off-lights on shenanigans could have been avoided, and people could have slept longer (and staff could have rested longer too).

You only get a chocolate square and small bottle of water.!

Overall good experience with boarding, and food. No entertainment was provided from Frankfurt to Delhi, that could have been better

In economy and food was ok, but with limited leg space (and I was in a 2 seat configuration) it was difficult to eat with a tiny seat tray. I spilt wine on my trousers. First time on British Air (I usually fly Turkish Air) and in a 777. Heathrow was pleasant but changing terminals awkward.

Starting with the flight Cairo to London the plain was so poor no entertainment at all uncomfortable seats although it’s 5 hours long,then an American airline plain took me from London to Miami it was a bad experience the crew most of flight time not available and they asked us to help our selves for any snacks if we need. From Miami to London actually was perfect flight with a huge plain and perfect crew but from London to Cairo was horrible plain with stiff fixed seats not movable no entertainment or wi fi very poor Menu which is unacceptable for a business class

I've done hundreds of flights in my life, and this flight was one of the best I've ever taken, From beginning to end, everything went smoothly, professionally, and with a smile and friendly attitude from all employees I interacted with. The food was delicious (and free), as were the drinks. There was just a genial and effective way in the way that British Airways organized the flight -that reminded of days in the 70's, 80's, and 90's, when flying was a fun, and exciting adventure. I enjoyed and had confidence in the abilities of the flight crew, I'll be flying British Airways several more times this summer. Thank you so much for the great experience! Cheryl Olso

Terrible! I missed my flight to my final destination and British airlines and American Airlines keep pointing fingers on each other’s. Nobody wants to take responsibility

Overall, terrific service, accommodations, and experience. Only reason comfort was rated lower was because it was difficult to keep a comfortable sleeping position for the overnight flight, but I also had an economy seat.

Very cramped seats in economy, difficult to get comfortable with your legs and feet and back. The seat width is ok but I’m average size. Food is HORRIBLE. Crew is friendly. Delays and very tight connections made it tough for navigating. We would have missed our connecting flight if it wasn’t delayed too. The terminal transit was slow and normally every 10 minutes before 8pm, after 8 pm is every 30 minutes!!!!! No free wine or drinks!! Below average attitude.

Leg room was better than expected. Lavatory’s were easy to access.crew was grea!

Horrible seat allocation. Boarding was slow. Food was average and so was entertainment. The TV terminal didn't work and so had to use remote.

Lost one checked bag.and wasted 30min waiting and filing missing baggage report. Very unsatisfied.

This was an American Airlines flight. The crew were very unhappy and quite grumpy. Abrupt to the point of being rude. The food was dreadful. Indeed the breakfast was in edible. I will avoid AA at all costs in the future.
