The app is very bugy, did not work well. Other than that it was ok.

The flight was delayed an hour and it was not disclosed to the passengers until it was time to board. There was no in-flight WiFI available and such poor communication overall. Unfortunate that I was going to miss my connecting flight with poor communication on alternatives.

Interline connection was terrible. Boarding pass from American didn’t work even though it was valid. Gate agent not present to straighten out the mess until the next to the last boarding group was called.

Very bad that in future probably will avoid Alaska Airlines. They had changed the flight schedule without informing us. Paid for check in bags online, got an email confirmation. But during check in they couldn't find it in system, didn't even bother to apologize. Check in agent wasn't helpful, just said if we had to check in bags we had to pay there. Even though email confirmation said we already paid, didn't bother to check and just said do a dispute claim.

The people were nice. I did not make my flight and they immediately gave me the next one out.

Short flight so really no interaction with crew and there was no food. It was on time and comfortable. Liked the plugs in seat in front!

Frontier airlines would have been better than this AA commuter flight.

One of the flight attendant was very rude and not helpful. The others were good. Also seats were dirty with food bags left on the seats. Looks like the plane wasn’t clean before we boarded.

Excellent, as always. Just a bit of comparison from the same routes. United has free blankets. Horrible terminal. EWR JetBlue. Updated terminal. EWR. Screens for each seat. Self service pantry and a lavatory in the middle of the plane. Alaska. Always has new planes neon lighting. Mood music for boarding and deplaning. No screens. Outlets yes. Offers water latter part of the flight. Which is nice. Excellent flight attendants. Customer service on phone or gates are always extra polite and friendly.

Quick, efficient, incredibly kind staff. It was a short flight (50 min)but still received beverage service. Treated my 5 year old like a star. Just endlessly appreciative.

It was terrible, if they ran flights on time it would make a big difference.

Delta seems to be improving in many areas, except they are super bad with the food available. Bring back normal food service on long flights.

I actually received a notification from kayak on email but not one by text from Delta when my departure gait changed and I almost missed my flight

New boarding doesn't make sense. Filling front first is slow.

Delta flight was great from the check in all the way to arrival. However, I had a very bad experience. I requested a wheelchair and the wheelchair employee that went to pick me up from the plane in Boston to bring me to the baggage claims told me I have to pay him. I was under the impression that it was a free service and I usually give tips but the person forced me to pay and since I said no because I was upset with his demand when my daughter walked in to pick me up he demanded payment from my daughter who paid him thinking maybe now it is a charged service.

Horrible. Grateful to be alive but spent 13 hours at airport only to return back to my familys house and flight changed to next day. They tried to fix a part on plane, had no back up plane and after 10 hours , reattempted the flight and it STILL wasn't fixed. We got a meal voucher and rescheduled flight but there should be some other compensation for the 15 hours spent in airport

My seat was changed at the last minute and I was moved to the last row, right next to the bathroom despite selecting my seat well in advance. I was also made to check my carry on due to space but when I got on the plane there was significant empty overhead space. Picking up my carry on from the luggage carousel added time to my trip which had already been extended due to delay.

There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

There was a loud squeaky sound the whole time we were flying.

Smooth flight. As always dinner could have been more generous. Breakfast was great.

Old and out of date plane, it seem like every time I fly with united there’s and issue. We were delayed,

We took off an hour late due to arrival airport not having enough gates. That was followed by 1:30 wait to get our bags delivered for the entire flight.

Wish movie and music choices changed more often. Mostly same from a month or two ago when I last flew.

It was good. Just that the seats could not be reclined. The people behind were not ready to let the chairs be reclined

Plane left & arrived early- 5 Crew great. Wi fi - paid for 2, only 1 worked - so so. Waste of $. Coolie was good

There was no USB plug in my section of the plane. So I could not charge my phone. Also, there was no screen to watch movie or anything like that. Wish I had known that in advance, I would’ve brought my iPad.

Made all groups except 2 check despite ample bin space. Inflight WiFi and entertainment didn’t work most of the time.

Seats are smaller and harder than other airlines we have travels with. Food was edible but no good. The sandwich was the only thing I would eat again. They did have a lot of movies to watch.

Not enough room between rows and food was gross. $160 baggage charge?! Never again.

I paid for what I got which was cheap, I brought my own entertainment. I knew what to expect, so I could be prepared. If you’re flying economy, check in early like me. I have no problems with my flight, was on time, staff were friendly, and overall good experience.

DO NOT BOOK THROUGH AMERICAN AIRLINES IF YOU HAVE ANY ADDITIONAL NEEDS. Great flight, crew etc. it wasn’t full so had space to stretch out Only downside was there was no GF option for my partner. We booked through American and it was a Qantas flight so despite contacting both airlines to confirm, she didn’t have a gluten free meal for the 16 hour flight (nor the flight in the other direction). The flight attendants did their best to accommodate but it was not super substantial.

After several delays and being rebooked onto a layer flight, I had to speak to three AA agents for baggage claim to get an attendant. All were in foul mode and reluctant to assist or offer any assistance.

Multiple maintenance delays and the missed and rebooked connection changed gates at least 6 times including one which had us walking 20 minutes to another terminal and then back again. Seated our family of three in different middle seats throughout the plane and then there was an empty seat next to me. Very long travel day which I would have never agreed to if I knew the itinerary would be changed at 5 am, 2 hours before takeoff.

It was as expected for such a short flight. No complaints

It was nice being on a flight that had working wifi. The boarding was quick - why don’t all airlines have small boarding groups window to aisle? Makes so much sense!!! I was disappointed to be the first person stopped to have to gate check my carryon. Especially when there was plenty of overhead space at the back! But I get it…keeps it moving. Crew was nice.

The flight encountered a delay exceeding 4 hours. The food voucher issued was valued at $12, insufficient to cover our meal expenses. Consequently, I was unable to take my medication, leading to a drop in blood sugar levels and exacerbating my anxiety.

Crazy seating issues. We got seated far apart. Offered middle seats at a premium rate. Why is a middle seat now the expensive seat? Baffling.

The boarding process was a nightmare and though we were traveling business class, we were in Group 2 and the organization was terrible. The Business Class on this flight was crowded and did not feel clean and nice. Overall, I would not travel Business again on the American Airline flight through British Airways Not nearly special enough for the considerable cost .

Not too impressed with them to be honest. They had forgotten my gf meal, despite the fact that the app had notified me that it was sorted. Apparently there is a ‘glitch’ in the system, according to one of the stewardesses, and has been for a while. Also the legroom in economy is way too small (and I’m a slight person) and are very uncomfortable. An extra Internal flight I booked via the app, had not even given me the option to order a meal, so was unaware of that and left without food on a 9 hr. flight !! Don’t think I’ll use AA again after this.
