I didn’t know that food needed to be ordered ahead. Please include this in the reservation information. Overall, very good experience.

Plane hit turbulence diverted to Houston. We'll probably get in after 3am

Given incorrect gate upon check-in, corrected by the gate attendant, D6 rather than D5, minor inconvenience. As with the previous flight, passengers were admonished to voluntarily gate-check carry-on luggage with the statement that those in the last boarding group would have no choice but to do so. If the Boeing 737 MAX8/MAX9 doesn't have room for carry-ons it's an interior design flaw on the part of Boeing. Posting an advance warning would be helpful, such as "Boeing 737 MAX planes feature limited carry-on space. Please be aware." SFO's amenities and TSA much better than MCO's. Crew was amazing! Brought my own food because Alaska's onboard selection has soy in everything. Beverage service was excellent. This was the first and last trip with Alaska after the previous flight's issues. It's no reflection on the crew of this flight. They were great.

I had a middle seat in between two large men. It was a redeye so needless to say I didn’t get a minute of sleep. One guy was pouring over into my seat the other kept falling onto my shoulder

Great price on internet. I love that WiFi was so affordable. Got a lot done.

Ground staff at LAX was very helpful. The Alaska lounge food and service is better than most airport lounges. I think the Staff are well trained polite and actually seem happy to work there. Great service Thanks 🙏 Jjk

The flight was very very delayed and arrived much later than planned. There was no communication about why or when our arrival would be. I would expect better and open communication about the flight but there was none. Also just pretzels? How disappointing.

Sat on tarmac for 30 minutes despite staring at three empty gates, one of which we eventually pulled into

It was ok. Alaska was adequate. Efficient and what I paid for it was fair. The boarding area at the gate was a joke. By the time they get past the C boarding group people all line up impatiently and then it’s chaos. We were boarding early then we sat on the tarmac for 30 minutes. I would of rather sat in the airport.

The flight was mostly smooth and quiet. No seatback screens.

Flight was 1/2 hour delayed leaving Phoenix. Otherwise it was an average flight. Flight crew on this trip was very nice.

Horrible - they lied to me about baggage & boarding, even though I specifically spoke to their agents the day before my flight about my issue. When I showed up they did not let me board and stranded me at my airport until I bought a new flight with money I did not have to spend.

The experience was great and much better than the flight going out. of course I was in first class but the service was excellent

Comfort of seats, ease of boarding. Food selection could be better

Food options were limited which is absolutely embarrassing for a Flight of this size The staff did not come around as much and I am not accustomed to such poor service from American Airlines Drinks I believe were limited to soda and water

Crew were attentive and friendly. Flight was smooth and early! I enjoyed the less crowded plane. Thank you!

We are gluten free, there were not any available complimentary gluten free options.

Flight delayed, boarding time kept changing, not good. Nee firm information given each time.

No meal on a cross country flight? SFO-MiA is pretty much the definition of a coast to coast flight. No meal provided. Sky high wi-fi rates too. Stop nickel and diming your customers.

The staff was unprofessional and didn’t communicate very well. The boarding process was very disheveled, potentially due to a power outage the previous day but there was no contingency plan to properly get passengers boarded the following day. Once boarded the aircraft stayed on the tarmac for over 45 minutes due to high winds. The communication was sporadic but an announcement was finally made an additional 30 minutes later that the flight was cancelled but we couldn’t get off the plane. Prior to deplaning one of the gate agents came on the plane and made an announcement for everyone to pickup their checked bags and take a card to rebook a new reservation because they didn’t have adequate staff. Flights were missed, passengers went to different airports and there was little to no assistance from AA.
