I like the big picture of the Eskimo on the tail of the plane.

I like the big picture of the Eskimo on the tail of the plane.

The crew members were wonderful. When we encountered a little turbulence, the pilots let us know and provided an estimate of how long it would last. Another nice amenity: every seat has AC power outlets and USB ports. It was a 6-hour flight, which seems a bit much for a single-aisle jet: over 200 passengers with access to only 3 restrooms (assuming you time it right and won't be blocked in by beverage carts); food is mediocre, over-priced, and (if you failed to reserve a meal ahead of time) the flight attendants have to process food/meal sales in the aisle. To access any entertainment, you must use your own device to log on to the plane's wi-fi (or bring your own entertainment).

The crews on Alaska Airlines are really wonderful. They clearly know how to treat passengers with kindness and respect. During my trip, I discovered that my upgraded seat had been changed when reviewing my electronic boarding pass. When I questioned the change at the gate, the two staff members acknowledged that the change was odd, checked on their computer, and confirmed that I still had my upgraded seat (i.e., the electronic boarding pass was incorrect). I was impressed by how they seemed to be "in my corner" from the start, quickly investigated, and provided me with a paper boarding pass with the correct information "just in case." All that said, I was a bit disappointed that Alaska Airlines uses single-aisle jets with only four restrooms (3 at the back of the plane, one at the front (ostensibly reserved for crew and first class travelers). I would understand for short flights, but for a 6-hour flight from Seattle to Honolulu...really? I will stick with Hawaiian Airlines from now on.

Seats are more spacious than other airlines that have you packed like sardines.

Barbara at JFK terminal for Alaska was very helpful in retrieving our boarding passes for our connecting and quite pleasant!! Thanks

The TSA line took over an hour and half to get through due to being understaffed and only having one scanner open. I got to my gate with five minutes to spare only to find out my flight left 8 minutes early. I needed help rebooking and had to pay to get a new ticket and was grounded for 24 hours. Not the greatest experience to start things off and had to completely rework my trip to accommodate the situation.

Being seated next to the engine was awful! I was nauseous the entire trip from pre-take-off, flying to landing. The engine vibration was very strong!

Everything was great but there were no entertainment options available.

The crew was the best I’ve had the experience of flying with. A misbehaving child was making things difficult for me with bopping my tray table, taking my snack, and continually tapping or bumping me. The crew quietly and respectfully moved me to another seat, and thanked me for my patience. They couldn’t have been more kind. Their professionalism really stood out to me and I am more than happy to leave a great review for them!

It was okay. Gate crew could be better organized. Wheelchair service for my mother was late as we deplaned. Flight crew was alright. I’ve seen better and worse.

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.

Friendly flight attendants. Comfort plus seats were very comfortable and had lots of leg room. 10A and 10 B.

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!

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. ☹️

Flight was delayed in the gate by 5 hours and ultimately cancelled- rebooking service by United agents was terrible

Flight was delayed due to the late arrival of the catering truck, which is quite unacceptable. There was a beverage service, but no pretzel, or cookie, or nuts were served in coach.

Not worth the price of premium class ticket paid, felt more like steerage.

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.

Everything was fine once we actually got on our flight. It was more then annoying they canceled (delayed) our flight. We lost out on a day of our trip along with money on our stay. Plus we had to book another hotel. So expensive.

This flight was canceled and delayed several times without explanation. The plane was freezing cold and no wifi for messaging. Getting off the plane was terribly unorganized and felt like it took forever….

The flight was delayed several times without explanation. The seats were terribly uncomfortable and wifi isn’t included. All these make for a less than ideal flight.

The flights was delayed by hours and it was the firmest landing I have experienced in my life. My back is still sore.

Internet service was erratic. Crew service was poor and slow. My luggage on this non-stop flight was lost and not recovered

Terrible. I didn’t fly and I had an important meeting the next day.

Equipment swap led to 2+ hour delay on international flight. And to top it off, boarding took forever.
