Departing flight for our weekend trip was cancelled due to weather which meant our return flight was useless. The whole thing was difficult to get support through but Alaska did recover and was able to reimburse us for the flights yesterday. For some reason, Kayak was not kept in the loop, adding to the confusion.

Departing flight for our weekend trip was cancelled due to weather which meant our return flight was useless. The whole thing was difficult to get support through but Alaska did recover and was able to reimburse us for the flights yesterday. For some reason, Kayak was not kept in the loop, adding to the confusion.

You sent me an email saying boarding was at 9:29 and AA sent one that was 8:29 on Sunday morning. I had to call AA to get that it was indeed 8:29.

The airport crew and on board experience was fine. The problem with Alaska air is that there is zero customer service over the phone when you’re trying to buy your ticket or change anything.

Generally very good. Waiting (due to de-icing and traffic) in plane to take off was a put-off. But it's not the airline's fault. I find Airbus more comfortable than Boeing.

Smooth flight, on time despite Captain’s forecast of troublesome weather conditions.

The flight was a disaster. It is a 40 min flight and we waited to the tarmac for well over 90 min with no updates, while the crew tried to reconcile the seating chart of people on the plane to what their phones showed. Terrible communication, systems and experience. I would do almost anything to avoid taking another Alaska flight after the experience last night.

Food was bad. Just a drink for a 5 hour flight

Leg and arm room are horrible. I am not a big person and found it tight.

You need a n/a category. Too short a flight for food. I love flying on Alaska from Santa Rosa Airport!

Late. Too long a flight for a 737. 0.5 oz of pretzels for a 5+ hour flight at dinner time. One step above Ryan Air/ several below Delta.

Great experience. Good dinner and service. FA's were very nice and attentive.

Jill was the flight attendant in first class she was fabulous!! Best flight attendant I have had in years.!! And I fly every other week. Other can learn from her!!

The business steward was absolutely amazing! Smiles and kindness! Wish all AA flights are like this one!

Never going to fly your airline again if it can be avoided.

Smooth flight. From the early boarding and all were on board before departure time and arrived early in ONT. Great crew. Thank you!!!!

Worst experience ever. Flight could not land in Charlotte for what we were told was a ground stop. Had to be diverted to Raleigh to refuel. Strangely during ground stop, our connecting flight had no issue taking off on time causing us to miss our flight. We were told there were no other flights that day to our final destination and that two days out was the next one. The only flights to get us there were from Chicago the next morning. Completely opposite direction but it was a direct flight. So we get flown to Chicago and have to find a hotel in our own dime. The flight in the morning was also delayed. Thankfully only a short time. The non too of all this, our luggage did not arrive by the time we were there. Communication was terrible, through the entire trip. Complete incompetence. Will never fly American again.

The flight was fine, once we got underway. It was more than hour delayed

The flight was significantly delayed for 6.5 hours because of snow. There was no communication once the plane returned to the gate regarding when the flight would resume. Other flights were departing while our flight was being unloaded for reasons unknown. Our flight also seemed out of the queue regarding further deicing, refueling, and waiting to Taxi to the runway.

They are always late and seats was also not having working charger

did not have enough meal for first class passengers so offer us snack
