My boarding pass birthdate was printed incorrectly causing me to spend an extra hour in a check-in and then again TSA line and to miss a chance to have dinner pre-flight. My window seat was given away and was replaced with a middle seat. I would have liked an opportunity to charge my phone and take advantage of movies but many of the departure gate chargers weren’t operational and I don’t know of an in-flight charging option, The flight left 45 late after trouble with unruly passengers, and I was glad staff removed them.

My boarding pass birthdate was printed incorrectly causing me to spend an extra hour in a check-in and then again TSA line and to miss a chance to have dinner pre-flight. My window seat was given away and was replaced with a middle seat. I would have liked an opportunity to charge my phone and take advantage of movies but many of the departure gate chargers weren’t operational and I don’t know of an in-flight charging option, The flight left 45 late after trouble with unruly passengers, and I was glad staff removed them.

Horrible. I likely will have to spend several thousand dollars to rebook my international flights, due to their delays, plus a hotel in SF. I can’t wait to never fly them again!

Pleasant flight, now wifi, but did get pushed to the exit row gracefully cause I am a tall man. Was a pleasant thank you.

Long flights are best when the seats have movies and shows to watch.

Good - San Jose security is a breeze. Exact opposite of San Diego. Flight on time. Bad - FA's were not that cheery or polite. I thought we may blow out a tire as the pilot slammed down a hard landing in perfect conditions. He came in pretty hot like he had a date waiting.

I was seated at the back of the plane and the flight attendants were fantastic. I did not get food so can’t say. Thought the movie selection was lean.

It was so easy to board using my boarding pass on my iPhone, and I liked what I was given on the plane for food and drink, and everyone was very friendly.

The messaging about the change in flight destination and options for getting to SFO was poor. There should have been frequent updates. When I spoke to the boarding agent moment before we were supposed to board, he was flippant and offered no help before the announcement was made that transportation would be arranged. It was as poor of an experience that I've ever had.

My plane ride down landed 20 min late. Boarding at SFO was strange too. The people at the terminal were nice—but, boarding lacked direction, and was confusing . Coming back was worse—the plane was hours behind—and I barely caught the last Bart train back to San Francisco (3 min more and I would have been in trouble). It was a very stressful trip, and it didn’t need to be.

The absolute coldest flight I’ve ever been on, even with a sweater and zip up sweatshirt. Was miserable the entire flight.

There was a loud squeaky sound the whole time we were flying.

Had a broken tray in business class. Crew just shrugged it off.

I didn’t like that I could not select my seat and was assigned a seat when I checked in at LAX

Great experience overall. Check in at Austin was congested as they only have about 6 check in kiosks, one was broken, and there was a lot of Spring Break travelers.

Bag drop off was slow and annoying. Only 2 agents at the entire delta desk, and no one directing traffic for what line to be in, many confused people slowed down the process. Boarding was fine. Seats in Delta comfort plus were fine. Snacks were great! Definitely a bonus. The entertainment system was awful — old, slow, not responsive, and completely unable to play games due to some kind of error. But on the other hand, thank you to Delta for the free WiFi. That made it better.

Everything was very good other than I had selected a specific seat when I booked the flight and they changed it once I checked-in the day before my flight. I was still in first class but lost my aisle seat for a window seat. Being tall, the aisle offers more comfort so I always select an aisle seat.

Flight diverted in SD. Later take off in Seattle by 1.3hrs

Crew was not friendly when I went to request a seat change.

Really impressive staff at airport and on plane, especially given how busy it was

Was a great smooth flight from Detroit to San Diego.

It was great with the exception of a rude desk member on the way back. And a terrible sandwich on the way back.

One of the best flights Ive had in a long time

My tray was broken and instead of being moved I was provided blue tape.

One hour delay. No Wi-Fi. Old aircraft. Nasty food

Was unable to check in online within 24 hours of departure

Overall, good flight and quiet cabin! Took the red eye home from Honolulu to LAX!

Couldn’t check in online. Unsure of terminal. Missed flight by minutes due to confusion and not being able to check in online pre flight.

Grumpy and rude gate attendant who was unwilling to help anyone who asked him for assistance. Too little leg room.

The food was lame for an almost 5 hour flight, but overall I had a good experience

VERY short notice (<24 hours) flight delay by 6 hours. Had to reschedule and pay more to book with another airlines.

Our original business class flight was cancelled so we not only downgraded but we were also spread out across the plane not sitting together in separate middle seats. My poor kids were scared and couldn’t see me on the flight and the crew wasn’t sensitive to the situation and what the airlines did to us. Very dissatisfied with United airlines.

The WiFi didn’t work and the seats are too close together. Very uncomfortable.

So so. Terrible aircraft choice for that leg of the flight.

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.

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.

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

Too many fees (but that seems to apply to all airlines nowadays)

For a 22 minute flight all you expect is for it to be safe and comfortable

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

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.

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

Our flight was great we left Kona earlier and got into LAX almost an 1hour earlier as well. LAX AA is in repair so to get out and found our bus to get pick up was a bit confusing.

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

5 hour flight - full flight - not enough room to use my computer - slightly delayed - Admirals club was excellent quality food, drink made up for flight seating. No food offerred on flight, you ahd to prebook.

We experience delays on departure and connecting flights resulting in 14 hour to our next departure. We were accommodated with a night's stay but was only provided a 12 dollar meals accommodation. The airlines rules state.at least 50 dollars. In any case, it can not make up for the whole day missed on our vacation in Sydney Australia.

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.

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.
