Flight be on time would be a good start. Then train your flight attendants to be attentive and friendly. This time they completely forgot my row for the measly snack! United, do better!

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

United needs to step up their game. Delayed flight leaving Seattle, San Francisco. Older aircraft, not very comfortable.

Had to cancel first flight because Airporter Bus took over 3 hrs to get to airport which resulted in an extra $378 dollar fare . Is there anyway I can be reimbursed for initial fare since it was not my fault? Sent from my iPhone EJ Ledet

The schedule to Moline changed 5 times. The gate changed 6 times. That is a pathetic way to run an airline. No wonder that no one in our company flies on United Express to or from Moline. Changes happen most of the time. I learned my lesson on this trip…never again!

Delayed by 2.5hrs any longer and they would’ve had to honour their own policy for breaking their own rules and regs. Not cool, especially when I have an infant child that needs to stay on a routine and they get schedules.

They had three choices for snacks - but you could only have one - and they ran out of the dark chocolate before they made it all the way down the aisle... Packed flight - limited service.

They opened my checked bag and even though my lock was tsa approved, they loose my lock and left my bag just like that. Incompetent people, very upset about it. I’ll try to avoid traveling with united

The new Airbus A231neo has neat tech but the economy seats are so tight together that I always had my shoulders against one passenger or the other. I was very miffed that Basic Economy REQUIRES check-in of bags other than your personal carry-on; if you want to offer low-cost airline prices and then add services for a fee, just let me carry on my duffel. Hell, I could have put my carry on IN the duffel and called it a day but the gate agent would not let me; I ended up paying $40 for the risk of losing my bag. Not the worst flight, but far from the best.

Flight was delayed by over an hour and gate checked bags took 15 minutes to be delivered to the jet bridge.

Flight attendants and crew were great! This plane was fine. It was clean and everything worked properly. Now, the gate change was not communicated. No text or information. It wasn't far with the gate change but it still changed without any communication. Not sure if this is on American or Kayakl. Also, internet was the worst. I would never have ATT. 3+hr flight and weak internet. I think I watched the commercials to get on at least 6 times. Terrible internet!

So excited very proud first of all I wanna thank kayak all updates very professional and fast alart And amazing cabin crew so nice to me they deserve big salute

Great flight - friendly and attentive team! Seats in coach were comfy, but a little cramped - but that is the case with all airlines ;)

Dreadful experience. Our flight was delayed more than 8 hours due to a maintenance issue and the assistance from rebooking was poor. I was travelling with a bad knee and needed assistance waited in one place more than 3 hours before someone came with a wheelchair. The woman next to me was a 91 year old great grandmother who had waited more than 4 hours. There were moments of support from the staff but it appeared as they were going against the direction of management. It was apathy, lack of ownership and dismissive responses with small moments of kindness and understanding typically from grey haired, female, veteran staff..

The only thing is if Wi-Fi is available after you land and taxi to the gate. It takes forever to get to the gate, and having the Wi-Fi continue would be great to bide the time at least 5 minutes before you arrive at the entrance. That is my only comment; otherwise, everything was good.

Airplane was cold. Flight attendants were rude. Phone charger did not work. No food available.

This flight was fine but had no time to breathe as the connection was late from Sea to ORD.. Super stressful. If we checked bags, the trip would have been very distressed.

Late and next flight even later. Who leaves at 245 am and arrives at 330 am ? No wifi, 4 hr flight and one bag of pretzels? AA should be ashamed

No problems on this flight. Entertainment system worked well. On time take off and arrival. Smooth most of the way.

Those seats were way too narrow. I had the middle seat, one person was a very skinny person and we still couldn’t avoid touching each other anytime one of us moved. The other person was larger and we were basically sitting in each others lap the entire flight. There was zero entertainment. The flight was long enough to justify tvs, but no. Gotta sit there in your infant seat and twiddle your thumbs.
