Healthier snack options in first class. Offer fruits, proteins, etc

Last minute change in gate to satellite N a bit of a hassle since I needed a wheelchair . Someone did come and get me to the gate but it was close. Then plane late. It’s hard on older passengers and families to have to trek from one gate to another.

Still seems like Alaska Airlines is not doing a very good job of anticipating the number of carry on’s going in the overhead bins. I was asked to check mine not to find out there was actually(surprisingly)enough room for my small luggage in the overhead bins. In the past, I’ve seen PLENTY of items in the overhead bins that should be underneath peoples seats.

It seems like most of the time theres no room for my allowed carry on bag. People are putting their things in the overhead compartment that belong under the seat in front of them. Getting tired of that!

The seats are too small/crowded. It is frustrating to be forced to sit with someone who is overweight as they crown the other seat. Nothing against the person…just the airline companies who continue(over decades!)to reduce seat sizes. Americans are fat. Those of us who are not are tired of being compromised by the airline companies who don’t faces that fact and make adjustments. Maybe have “overweight seats”? Maybe give us a discount for being forced into an uncomfortable flight due to others overweightness? Please, make adjustments…be accountable. Thanks!

The crew was great and everything went smoothly coming and going.

No outlets, plugs, way to charge the phone or service and no food on one leg o the trip, but other than that, great. Loved WIFI, the flight, the crew, the pilots, the schedule, etc. Great job. My new favorite airline!

Wonderful as always! Pleasant staff, smooth ride, and timely departure.

Flight was scheduled to leave at 6a and delayed for 5 hours due to “mechanical” issues. Everyone else on the flight received an email voucher for $24 of food for the delay, except for our group. Also the carry on luggage bins were full and the crew requested that everyone to pass their carry ons back up to the front while everyone was still standing. They gave no other direction and kept rushing the process. After all bags were sent up, they then asked for seat #s to go with each bag… They should have probably had everyone get to their sits and then pass the bags up in a controlled process.

Nobody’s fault but turbulence all the way meant no service and no access to the bathroom,

Flight was delayed at airport with large backlog and WiFi was spotty

I don’t like mushrooms and that’s all they had with pasta

I Love Delta but one of the flight crew training in courtesy snd hospitality.

I don't know why the crew decided to board 15 minutes early without informing anyone not at the gate. Why would you have the app send a notification that we're boarding on time, instead board early, and then rush me to the gate. Then have me check my carry-on when I specifically packed my bag as to not do so.

Could have been on time and not missed my connection

Really hard to tell what was happening after my flight got delayed five times

Flight was delayed from San Diego due to being overweight for weather conditions. We missed our connecting flight to our final destination due to the delay, as well as the connecting flight leaving before the scheduled departure time. We missed the connection within 10 - 15 minutes. We were booked on a later flight arriving 7 hours later. There were 7 passengers sharing the same originating and connecting flight.

Horrible, mismanaged ground issue resulting in a long delayed, next flight left early, waiting extra 7 hours in the airport, screen did not work

I missed the flight because the Minneapolis flight was 49 minutes LATE, and the Boise flight LEFT 24 minutes EARLY!

Having to up charge for a seat assignment is not good. Delta can do better

Very disappointing that on an international business class flight they would not give me access to the lounge in Boston. They said it was because it was a codeshare flight. International business class should include lounge access regardless of codeshare.

They did not have free WIFI and I was not okay with that!

Flight was on time, clean, etc. Despite connecting to your wi fi I was unable to use your app to watch entertainment.

Awful!!!. I do not recommend United. The flight staff are unhappy and don't attempt to make the passengers feel comfortable or welcome. The food is not edible, and the seats are miserable. My expensive luggage was destroyed, and the ticket prices are too much for the experience.

Even though the incoming flight was delayed by 20 minutes they managed to get us to SFO 15 minutes early.

On time, easy boarding. Anytime you sit in an economy seat, it’s uncomfortable. New plane and the bathrooms were in the galley at the back of the plane which seemed odd.

It was fine for the most part. But the volume on the announcements was way too loud, and the cabin temperature was chilly. We had the hardest landing I've ever experienced- I think it hurt my back, and the tires squealed when we touched down.

Great, except the canon was so cold. Even the flight attendants put jackets on

Did not like the check in guy quibbling over a couple pounds at the luggage weigh in

Just having a little bit more legroom would've been nice.

The flights to and from Cincinnati were great at being on time for both, departures and arrivals. The planes could use some updating.

It was a dismal experience. The flight was delayed for 4 hours, and we spent hours in the plane, without air, during the summer. We were not provided with water, and the medical assistance was inadequate when it arose.

The landing the pilot was very smooth. The flight attendant was kind of rude.The boarding the plane in punta Gorda was not great made us wait out in the heat 😞

My exit seat was very comfortable Coffee was to be purchased but sodas free 😏

It was poor a four hour delay and no explanation for the delay. What’s a 35 dollars going to do. It also made me miss my car rental,

It was on time. Flight was comfortable. Staff was nice. It was the way a flight should always be.

The price was the only good thing about this flight. It was scary during takeoff when the plane tilted side to side. It made me feel very nervous as I have never had a take-off that unsmooth. There was no on-flight movie or music options and the only complimentary option was water. Other airlines offer trail mix or a caramel cookie and pop options as complimentary. This flight was a 2.5 hour flight. I understand for shorter flights not having options, but a flight 2 hours or longer should offer more complimentary options and in flight entertainment. Also the seats did not recline and for a longer flight reclining seats are a must for comfort.

A very pleasant flight but it would be greatly improved with wifi to help entertain kids

This is a no frills, get it done, efficient airline. The seat is a lawn chair. You better bring your own entertainment. If you want something other than water you need to pay for it. But they will get you to your destination quickly, on time, and then they will turn the flight around and go right back where they came from. Reliably. Couple times a week tops. If it fits into your schedule, you can’t get there cheaper or faster.

A three hour delay to board and then another hour on the tarmac because they couldn't get a tractor? Ugh.

Horrible. Flight was delayed for 4 hours first till 7pm. Then for one more hour. Then again and around 9pm we were finally boarded and waited for catering delivery for another hour. At 10pm we were not interested on food at all. Tired, sleepy we arrived after midnight. Insane.

The forward head smelled putrid and urine soaked, worse than any head in even transoceanic flights. The wifi stopped working after about an hour of flight.

Wifi was good on the flight from DCA to Dallas and terrible on the flight from Dallas to Tucson. The forward head in the flight from Dallas to Tucson was putrid smelling entirely urine soaked. The flight from DCA to Dallas was delayed by almost 30 min with a plane change.

As per usual for my flights with American Airlines, One flight was very delayed and caused me to miss my connection and they moved my flight to another day. I called customer support and was moved back to my original day but different flights. My layover flight was delayed by an additional 30 minutes while the flight crew confirmed that the plane was airworthy. Ultimately, it is less hassle to drive 10 hours than to fly 6 hours with American Airlines. I recommend my friends and family to hitch hike over taking this terrible transit.

On time departure was much appreciated. However, as a frequent flyer and American Advantage member, I was as disappointed not to get an aisle seat.

I've never seen such poor lack of information at a gate station in 69 years. The flight from COS was to depart at 12:37pm. At boarding time, the gate agent in the microphone mumbled something completely unintelligible. I understood one word. "mechanical". Nothing else. Absolutely nothing else was reported for the next 1-1/2 hours. Past the time for departure, at 12:37pm, the gate agent simply walked away and the station was left unattended, as all of the passengers waited expectantly. The board still said that the flight was ON TIME. That was hard to believe since it was then well past 12:37pm and we all were sitting at the gate and there was absolutely no gate agent anywhere in site. I stopped an employee who was standing somewhere else and said that we can use some information. Much later, the same gate agent said that he will have information for us about 5 minutes but he "doesn't know any more than you do." Of course, five minutes came and went and he did absolutely nothing. One and a half hours after 12:37pm, he opened the door and began boarding. No explanation, no apology. Once we were boarded, the same happened on the plane. We sat. No explanation, no apology, from any flight attendants. Finally, finally, a pilot apologized and explained that there would be a delay. WELL NO KIDDING !

American Airlines put the food on the wrong plane which had already taken off by the time we took off so we had no food on the plane.

With weather and severe delays it was disappointing we didn't receive any compensation for the 5 hour delay. Not even a food voucher.

Flight delays for communication overall not a good experience uncomfortable on the plane. Person in front of me reclined his seat, putting them inches from my lap.

the plane was so hot!! the air-conditioning was barely blowing. The flight was delayed, and we had to sit on the hot plane before take off for an extended amount of time, waiting on international passengers. Would not have been so bad if it was not so hot. They said it would get better after take off, but it did not.
