delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

This was a Lufthansa flight. Disappointing main meal. Very rough over Canada and arrival at FRA. IFE was almost unusable.

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

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.

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.

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

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

I contacted both carriers months beforehand to change the cabin (booked in April) but to no avail (united asked to contact Swiss since it was their equipment, Swiss told me to reach out to united). So yeah… My seat was pretty worn down, legroom on 27K was more than enough, but still economy seating so, getting to know your neighbours was easy. According to ground staff, the flight was massively overbooked- and this showed. I ordered a gluten free meal beforehand (which was honoured) but for breakfast got a bread roll and croissant 🤷🏼‍♂️ The connection itself is great. Leaving SFO late PM to arrive at ZRH in the afternoon makes it easier to get re adjusted again. However, and since I’ve flown this connection a couple of times in the past, I will rather deal with one carrier only and include a layover on the east coast.

Somehow I got “offloaded” even though I had my boarding pass and was in transit Food is horrible Staff were nice and cheerful No headphones were provided on 11 hours flight

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

Plane was good but was delayed. probably not AA fault but caused a 1 hour delay. Seating was cramped.

The staff were very helpful with lots of refreshments on offer. The toilets were clean. The seats were comfortable and entertainment was good. No complaints, it was excellent.

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

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

If they could pack the seats closer together they would...

Nothing really nondescript, the flight attendants were friendly and helpful.

Gate changes 30 minutes before boarding was a real inconvenience. Especially since it was from Terminal A to C. This is the second time this has happened on our trips within a month of each other

On our return trip we were able to get on an earlier flight. American airlines made it so easy to do & at no cost!
