Our landing was rough. Asked other passengers, and we all agreed. The actual touchdown was very abrupt. Breaking was aggressive, as the nose of the plane went left and right.

We landed at 7:35 pm did get out of the plane till 8:45 pm pilot informed that their was a plane broken down on the gate that the plane was to go in that it would take 5 to 10 minutes, after 40 minutes the air we were breathing started to be bad and people started to complain so they turned the air full blast and the pilot as I was walking out of the plain was laughing like nothing had happened (very un professional) ( I would never fly Alaska again…..)

I’m a small lady , I was in the middle seat and could barely move . My muscles were cramping most of the flight . Very uncomfortable!!

We brought our own food on board. Did not use entertainment. Airport agents knew my husband arrived in a wheelchair and they moved us forward in the cabin from assigned seats. Such a gift! We requested wheelchair assistance when we reserved the flights, but the request disappeared from all 4 legs of round trip. However, very easy to add at the airport.

We had no food or enjoyed entertainment. Flight was only about 1 hour. Lovely experience.

Be prepared for departure delays at SFO while the runways are under construction. No fault of the airlines, so be flexible. Alaska is my favorite air line but needs to pay flight attendants for all the time they're at work, not just when in the air.

First time traveling on plane, everything was very easy for me.

The flight was delayed for about 3 hours . It would have been better if more explanation was given why. The flight crew was excellent and the service was great

The staff were nice and the plane was clean, but charging for everything beyond the ticket was, quite frankly, poor customer service on your part. A cross-country flight should include at least a sandwich and one checked bag. This was my first Alaska flight and was booked because of convenience, but it might not have been worth it because of the baggage fee. United had free wi-fi and free movies, at least. Southwest allows for one free checked bag and has prices comparable to yours.

I couldn't cancel or change my flight so I paid for nothing.

Flight was 3 hours late so only had an OK experience

It was very cold because the air conditioner was on high power, and my son got sick.

3 hours late and all they have is was a $12 meal voucher. That’s not even enough to cover fast food.

Among the poorest flights I’ve had with Delta in a while. Entertainment system failed completely on a 7.5 hr flight. Crew seemed distracted and not the normal friendly crew. Flight overbooked it seemed… very crowded.

If I can, I always fly Delta. I’ve found their service to always be reliable and pleasant.

You could have not cancelled the flight (AA, which I will be flying from now on) left for BOS despite the fictitious weather issues (that no one in my Boston family could see). You could have rebooked my direct flight to another direct flight instead of sending me though JFK, the worst US airport after O’Hara You could have rebooked me on a Main Cabin seat (like the one I paid for in my original ticket instead of putting me a the last row on JFK->BOS leg, pocketing the difference in ticket price But I do not really care whether you will ever do that in a future because in a future neither I nor anyone from my company (unless they pay out of pocket) nor an of my clients and partners (if they heed my advice) will ever be caught dead on any of Delta flights

Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

It was pretty good I was worried with the short Layover that I might not catch my connection but the gate was there

It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

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.

Was 4 1/2 hours delayed. No food options, poor entertainment and cramped seats made worse by people in front reclining while we could not as in back row.

The baggage handlers broke the handle on my bag that they put under the plane that I checked on the jetway. They traded it out for a less quality bag in Tulsa. But, they said they would try to fix it. Bologna! There was no fixing that bag handle. Someone didn’t care how they treated the bag.

The entertainment wasn’t playing in the app or online.

It is a modern tragedy that any airline expects you to travel for 14 hours in such discomfort and that the only way to add comfort is exorbitant prices. I was in pain by the time we landed. Shameful.

Original plane sidelined. Had to wait an hour for replacement.

Crew was very cooperative and professional. Passenger's first checked in bag should be free.

No real agent onsite helping you for missing luggage there. Not like the other airline next to UA desk, they have staff attending in their desk assisting answer/helping luggage issue, even after midnight.

Horrible, the flights kept delaying, so it is obvious that we won't be able to make it to the next connection. No easier/real agent on site to help you figure this out. UA agent on other counters refuse to assist you and direct us to use the QR code/call customer service. So inefficient and poor. While technology seems convenient, but it's not the best interest/experience for customers need help while there is active issue need assistance.

After the morning frenzy of 35 min wait through CLT security at 4;30 AM, it was nice to have a smooth pleasant boarding experience. This 6:30 AM flight was not full. We were able to get seated swiftly and took off promptly. Nice touch they distributed the old fashioned headsets with 8 mm jacks. Snacks were decent and arrival was uneventful.

My window shade didn’t work. So I missed coming into my city. ☹️

From check-in staff to in-flight staff, everyone was wonderfully kind

What an idiot at the boarding gate. Even flying First she was mean and unpleasant.

I missed this flight due to delays on my previous flight.

This flight was awful all around. Delays on the tarmac at PHL before takeoff and at the tarmac in Chicago caused me to miss my final connection. This was completely avoidable, in my opinion.

The A321(?) model of the flight for 5+hrs has no seat back screens. Getting the american airlines wifi experience to watch movies on your own devices is not the same.

For the money that I paid it was a good deal. I sat in the back of the plane and didn't pick a seat and my wife I sat together. Mission accomplished.

Seats are weirdly bent, I felt hunched the entire time.

Paid for premium economy had no tv the whole time the crew tried to reset/reboot but would not work they said they would put a trouble ticket in for it. We had 3 seats my tv was the only one that didn't work. They cancelled our flight re worked us on another that left us at airport over night on the floor I have a ten year old and a 78 diabetic mother which also had shingles and suffers from nerve pain in legs and back. Requested wheelchair service at all airports after the re route NO wheelchair service was there to help. WORST experience we have ever had. Went to American airlines assistance it was closed. I AM FURIOUS!!! I expect some sort of compensation from this traumatic experience and no need for flying points we don't plan on using American airlines again!!!!

This is by far the worst experience I have had with American Airlines. The start of this trip was a complete disaster. I purposely planned my trip so that I would weather any delays so that I could make very important meeting at the Pentagon. My flight was cancelled because of maintenance and I was put on the first flight the next day but I was late to the meeting. After a long week at the Pentagon I just wanted to go home and my flight home which was early in the day was delayed. Eventually the flight was delayed until the next day. I was not authorized a hotel room because DCA was my point of origin. So I paid for a hotel out of pocket. The flight this morning was boarded then deplaned because the aircraft was hot. The flow of information was not happening in DCA and made it worse when the news was bad. I am going to take a break from American for my next few military flights. Hopefully whatever has been going on with American Airlines will be resolved.

We had a 2 hour delay. The seats were smaller than most other airlines. The person in front of us wanted to lay back and we had to stop her because she was pressing against my girlfriend’s legs. We had to ask her to sit up and not lay back due to the lack of room.

They never updated the boarding pass on their apps to show their delay

Online check-in was not user-friendly. Too many fees, not cost effective.

They wouldn’t let us on the flight even tho we were an hour early. No refund not even our bags that were prepaid

I brought a ticket and car rental through Travelocity. There was no where to add a KTN. So I thought i’d add it by looking up ticket on frontier website. I tried 3 times with the frontier chat bot to add my KTN it never updated my boarding pass. So then I tried showing up early to do it in person at the airport. The first employee update my ktn in the system and gave me a new boarding pass. I was sent back by tsa to join regular line. Then I was told to add my Ktn. It would cost me $25 extra. Given the length of the cue I did pay. Congratulations! BUT I will NEVER fly frontier again. Plus the plane was very old. It had actual ashtrays and old looking tray backs. Worst travel experience ever. Im warning my friends and family not to use frontier ever.

I did not enjoy the trip home on Frontier for several reasons: there is too much cost besides the flight, which was more than I would normally pay, then having to pay for luggage, and carry-on, seat (if you want to reserve when booking) then you must pay over $3 for a can of soda, and $4 for a snack. A cup of water is free.

Did not realize seats did not recline. Best to travel in an exit row... No question

I strongly dislike Frontier. I find them barebones, the seats not particularly comfortable, the nickel and diming is maddening, the app is TERRIBLE - super confusing to navigate, and the last 4 frontier flights I have flown have been on AVERAGE 2 hours late, one ruining a fancy night out in Vegas with reservations made well in advance, which was nodded to with a measly 5000 miles, which translates to almost nothing. At least credit a free checked bag or something.

8 hr delay. had to buy another ticket with another airline

Four and a half hour delay in total. What frustrates me most is the poor communication and disorganization.

I appreciated the upgrade to free cary-on bag and seat selection at no charge
