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.

Very comfortable seating and the Flight staff were very attentive. The premium economy section that I was seated in was very clean, updated, and well appointed. I would highly recommend flying United Airlines as this experience was better than the Japan Airlines business class that I flew several months ago.

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

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

We fly to Ecuador frequently. Checking in is usually a hassle because most United agents take some time before they can verify that my passport doesn't require a visa to Ecuador. This time the process was even longer due to the cyber attack. But she was really nice to us. So glad we brought plenty of snacks to supplement the 3 flights from SEA to GYE.

We had selected seats in the app that were a 2x2 format in the middle of the plane. Our seats when we got on the plane had been moved to the back rows in a 3x1 format. What’s the point of paying up for tickets that allow seat selection if the airline will just change them?

Both flights were late by about 30 minutes .. Other than that, everything was ok..

We did not have enough time to make our connecting flight. As a result, we were put onto a different airline for our second leg. The different airline was NOT comparable to British Airlines, and our arrival was significantly delayed. The actual flight on BA was amazing.

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..

Everything was great except it became so hot on the plane I couldn’t sleep on my red eye flight. It didn’t really cool down till we started descending.

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.

Experience was fine. Seats were cramped, and we had to wait for repairs before we could take of. Even though the door remained open, we were warned that leaving the plane could cause difficulty trying to fly out later. Staff was pleasant, and climate control was fortunately working. We had trouble at the DFW terminal, but I don't think that was AA's fault.

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.

Boarding, Seating, Flight Attendants, flight was okay. My seat was uncomfortable.

Wow! Both way we came in in advance! Now that's a first with AC!

SIX HOUR FLIGHT DELAY!! $15.00 voucher to apologize. Missed our first tour in Quebec.

The take off was delayed as we were told that the baggages had to be rearranged to balance the weight. I only took a carry-on and a personal item, but the overhead bin was extremely small, even a normal size carryon can’t fit it, so they had to check it in for free. The seat was really tight and no entertainment at all.

The Montreal to Barcelona flight was cancelled half hour before boarding. We had to struggle for hours to find an alternative route through a very long route with 6 hours of transit time in Munich. It wasted almost one full day of our long awaited vacation. We are extremely disappointed.

A220 plane had 5 seats across which is great for couples who can snag the A&C seats. Seat itself is borderline comfortable but still tough on a 5+ hour flight. Overhead bins are small so if you're not in at least boarding group 5, you could be in trouble. No included food service. Non-alcoholic drinks are free but even the most basic snacks are for a charge. Price was reasonable for the only direct SEA-YUL flight. Boarding is efficient even managing passport checks. Worth flying for the direct flight.

It took 66 hours to get from Seattle to Tel Aviv. As a minor, I was left for more than 12 hours in Toronto and Frankfurt without hotel and food vouchers. It took 5 layovers. It was insane and not okay

Well it was cancelled and we were forced to sleep in a closed airport, check back in at 4:30 for 9 am flight that was also delayed an hour…

The flight was 4 hrs 35 minutes long, the good and beverages didn't come to us until over 2hrs into the flight. The boarding was confusing as the employee flipped the sign right before boarding started, which confused everyone, she was very apathetic.

Full flight with a newer aircraft was comfortable. Would like to see some complimentary snacks on a flight over 4 hours. The flight crew was very nice.

Flight was late and then they made us sit on the plane
