My trip was delayed by more than two hours and missed my connecting flight to Fiji due to delayed they have to change my flight to United Airlines and stranded in San Francisco for 24 hours waiting for United next flight after almost 3 days I finally arrived in Brisbane airport but my luggage wasn’t here and now I still don’t have my luggage and still without my clothes and my needs. The first full day of my vacation is horrible because I don’t have any clothes and still trying to contact airline for luggage update and hopefully they will tell me the truth instead of misleading me and I end up waiting around without enjoying my vacation time here in Brisbane.

My trip was delayed by more than two hours and missed my connecting flight to Fiji due to delayed they have to change my flight to United Airlines and stranded in San Francisco for 24 hours waiting for United next flight after almost 3 days I finally arrived in Brisbane airport but my luggage wasn’t here and now I still don’t have my luggage and still without my clothes and my needs. The first full day of my vacation is horrible because I don’t have any clothes and still trying to contact airline for luggage update and hopefully they will tell me the truth instead of misleading me and I end up waiting around without enjoying my vacation time here in Brisbane.

I was offered a selection of drinks and given a free snack. The flight was only a couple of hours, but we were trreated better than the transatlantic flight.

I was much more comfortable on this flight since it was not completely full. Again the complimentary food was inadequate for such a long flight. A tiny bag of mustard flavored pretzels and small drink . I'm glad I brought a few granola bars with me this time.

Plane was clean and modern and spacious, usb ports all worked. No TVs

Baggage pickup in Seattle took over an hour. We were told one, then moved to another, and then back to the original. What should have taken 15 minutes took over an hour. When waiting to board our flight in Seattle to return to DC, we were sent to 4 different gates before finding the right gate. I have walked every inch of Sea-Tac Airport. The actual flights were great. The rest, not so good. "Ain't no way to run a railroad."

Room is great! Excellent value. Boarding & service extremely good. Food was the worst I’ve ever had on a plane.

It was nice this is not the first time flying with Alaska

Flight was delayed 30 mins due to logistics, but it didn't affect travel plans in a significant way.

You guys did great, the only thing keeping me from the higher rating is the physical dimensions of the seats, which staff has no control over. Keep up the good job.

I had to gate check my luggage and it was a pleasant experience as I never done that procedure before. Everything went smoothly.

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!

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.
