Departing flight to San Diego was delayed. Return flight from SD to SBP was delayed. Not terrible but not ideal

I loved that the checking in process was seamlessly easy and user friendly. The crew was very nice and professional. Unfortunately, we were seated in the back of the plane across from the bathroom. There wasn’t much room for leg room and comfortability. Alongside, we had to listen to a baby crying up and down the aisle way for the entire plane ride. The turbulence of the plane landing was rocky. Overall, the experience with Alaska was just okay. We made it home alive so that’s always a positive.

would have been nice for flight to not be delayed by 2 hours so that we had to pay $80 to get home since BART had shut down. i thought a 10pm arrival would leave enough time to account for delays but i was wrong.

One of the best roundtrip flights I’ve ever been on. We needed assistance for my elderly mother and without fail, each and every Alaska team member was helpful, kind, and patient. Will fly Alaska again and again.

Delayed flight both ways. Then, on the return flight, we were stuck on the tarmac for at least 30+ minutes. Idk what happened, but this was a bad experience.

I liked Alaska better than other carriers that I have EVER used. Unfortunately, the plane from LAX to Guanacaste leg of my journey had some mechanical problems and had to return to LAX - causing my journey to be very long and added a day to my total trip. The Airline was very prompt in offering their apology and have given me credit to use for my next flight. I thought the terminal in LAX was too cold for comfort, especially if there is a long wait between flights.

Coffee or tea service would be nice for an evening flight, water or juice not good enough.

I am always uncomfortable about the boarding process. I think every airlines has their own procedures for boarding but all of their procedures are inconvenient because it takes too much time to board. If you board people from back seat to front, I think you can reduce the time to boarding.

Good leg room, no problem with overhead storage and the staff was super helpful.

There was a delay, then we were boarded, then deboarded, then waited another hour for a new flight, then boarded again and arrived 2 hours later than expected while traveling with 3 young children.

Boarded plane and then delayed 1.5 hours while on the plane

Horrific. They missed my connecting flight to San Diego. I didn’t get there until Monday at 9am when I had a mandatory court settlement conference scheduled at 6am since we had parties on the east coast. This caused many issues. All because United apparently forgot to hold the doors open until my flight landed that only had a 10 minute delay. This was the last flight to Southern California. So I couldn’t even rent a car to finish the trip. United cannot be trusted when traveling on specific days and times since weather didn’t have anything to do with the delays.

My flight was delayed a very short period of time but they did not hold my connecting flight to San Diego, also through United. So they closed the doors before we got off our plane. They would only have to help the door open for another five to ten minutes. So I missed a court deadline for a manditory mediation settlement conference for my client. I had to get an associate to be there in person and be on the phone with him relaying what he needs to do the entire time. The court was very upset with me and so was my client. United cannot be trusted.

We were given vouchers we couldn’t use with a 5.5 hour delay

Really good 😊 the woman at the gate entrance was a little rude checking in our carry-on but i dont think she worked for the airline, she worked for the airport at sacramento, other than that amazing.

Boarding was mayhem. Late boarding by 15 minutes because of lack of staff (missing 1 flight attendant. We had to wait for an arrival of another plane before we could board). Flight was a little rough, but cannot blame on airlines.

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

Excellent service despite turbulence during the flight. Flight attendants were remarkable!

United out of SFO is having issues with catering so none of our meals were loaded on the plane and no offer of compensation for our tickets purchased was offered.

A bit rush for transit. Food and entertainment are not available

Flight was cancelled 3 hrs AFTER etd. Thetefore Missed connection from JFK to New Zealand . No accommodation provided… This cost ne aporox 1000 USD in extra expenses and turned whst should have been a 24 hr trip ftom Boston - New Zealand into a VERY expensive , late 70+ hr nightmare … Complete nonsense!!!

Amazing food, great staff, with one noticable detail missing ...but no seat entertainment in any of aircraft ...I am not a fan

Boarding gate in Honolulu was staffed with a great clerk with a soothing voice despite the flight delay of over an hour. Flight attendants in the plane were all grumpy, not pleasant looking bunch. Their sour attitude showed throughout the flight. Inly able to get a select few movies started. Most of the movie links in the “free entertainment” did not work.

This was a horrible experience. For a first class experience, my chair was held together by 3M tape - and I have a photo. The crew weren’t very attentive, somewhat dismissive and forgot my drink and snack, the chair reclined about 3 inches on a 6-hour cross country flight. I was also not informed that there was no lounge available in Newark airport because of renovations, so all around this was one of the worst experiences and I would actively avoid both American and Alaska Air going forward.

Boarding was very efficient. Everyone got on board and we got on our way very quickly. It was frustrating that the entertainment app was not functioning properly. I was not able to activate some of the movies offered. The crew on this flight appears to be pretty grumpy. They had no smile on their faces. I felt like they were doing us a favor for being there.

Loved the staff, boarding and drink options! Wish the comfort of the seat could have been better nevertheless

Honestly, I haven’t flown American in years, probably due to the pandemic and my being unable to travel for certain periods in the last two years, but it was a good experience to dig out or obtain a new American Airlines account after many years of traveling for business with American in the past.

Long 5 hour and 45 min flight and only one drink service and cookie snack

Whenever a passenger purchase a ticket his advantage number should automatically to his information. It's not everyone remember the number. You request for your number and American airline agent say they will email it....and they never email anything and you loose your mileage just because you don't remember your number. It should automatically go your information and associate with your email account at all times

I miss the screens they used to have for the long flights. I use a Kendal and it doesn’t work well with there WiFi. I tried my cell and the wifi was not good for it either this is the free wifi.
