First class only upgrades seat width. The bottom cushion of the seat sloped forward so much that I was constantly sliding out of my seat. The meal was awful, granola and dried fruit? Seriously, for what I paid to upgrade? I can bring my own sawdust and rotten fruit for a whole lot less. Priority boarding is great except when you have a hundred economy passengers stranding in the aisle slamming you in the face with their enormous carry ons and smelly asses right under your nose. I want my money back for that leg of my trip. It wasn’t worth the money for such a minimal upgrade.

I had never flown Alaska Airlines before. I’ll definitely use them again. Seats were comfortable and roomier than expected.

Seats lack shoulder and elbow room. The lady next to me was short and slightly heavy with knee problems, she kept jabbing me with her elbow while playing her game on her phone for 2 hours, the duration of the whole flight. It was frustrating and annoying! I was in the middle seat, there was no space to adjust to avoid her arm jabbing me.

I was in second from last seat. My luggage was in row 15. I asked the stewardess if I could move up before the plane lands. There were 3 empty rows. She went on to explain to me, how no one was sitting there when the plane took off and there was no education on the exit doors. Blah, blah, blah. I said ok, S he kept over explaining to me. So whatever if that’s the rules. She went in the back to the other 2 stewards to tell them the entire conversation I just had with her. Not only could I hear her so could all the back rows of the plane. This was very unprofessional and inappropriate.

Soda cans were mini-size; snacks were teeny. Options for entertainment on trans-continent flights were bad - no seat screens and no way to support device (as seen on other airlines) so had to hold device in position. Just overall, not good (compared to United)

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

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!

Flight was good, boarding was a breeze, flight attendants were friendly and professional. There was a medical issue with another passenger and the crew handled it in a calm and professional way.

The net issue I had was with the gate agent. We had added a carryon to our boarding pass when we checked bags. When I got to the boarding gate the agent was rude asking why I had a backpack - I said I added it - even had an orange tag on it. She ripped my tag off and swung her monitor around to show me how she was right- saying it isn’t wasn’t listed - only a checked bag. I explained again that I wasn’t sure what the issue was but I wouldn’t have an orange tag if I hadn’t added it. Then she finally checked my husband’s boarding pass and found that the agent at checkin had added my carryon to his boarding pass instead of mine. She sent me on my way without my orange tag. Was a bit embarrassing for me the tone she used with me assuming I was trying to get away with something.

Gate agent asked if I could switch seats so a family could sit together. Agent moved me to a seat in the front of the plane, no charge. It was easy. The agent did a great job.

Great seat space. However food and drink prices outrageous. Jabbing to pay for a carry on bag or stuck paying at the gate too much.

Every Allegiant Air flight I've ever taken has been delayed. This flight was delayed a full 2 hours. It was excuse after excuse after excuse. It was a flight from southern Florida. They made us board the plane on time, but made us wait for 2 hours on the tarmac. Because the engines were kept shut off, so was the air conditioning. One can only imagine how hot the air was in the cabin over those 2 hours on the tarmac, while in the hot Florida sun. Just terrible.

Actually, for the price, I'm willing to put up with a little discomfort (upright chairs) and at times inconveniences (like any airline), lack of entertainment (I can bring my own). My flight was non stop and smooth. I would fly this route again.

The flight was delayed 6 hours and we were only offered an $8 food credit. My husband stood in line to get the credit for 45 minutes and when he got close to the end of the line the computers went down.

Worst ever! Flight cancelled supposedly for weather even though we k ow of many others who flew into Bangor same time no problem. At the airport there was no customer service at all just refund and no possibility of rebook for 3-4 days. Aweful won’t fly with them again!!

It’s a budget airline so adjust expectations accordingly. Nothing is without a fee but such is necessary for tickets to remain so affordable.

No complaints. It’s a budget airline so can’t expect any frills.

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

My seat was broken. WiFi didn’t work. Gate crew at HOU were rude and condescending. Treated all the passengers badly. Bad experience, United.

This flight was delayed multiple times and eventually canceled around 2-3ish. Original take off time was around 10:30am. By 3, there were no other options out of Houston, so stuck in Houston for from 3pm - 11am the next day.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

There was a group of school age passengers that were very loud and unruly with their chaperones were no where to be found.

On time every leg of the journey and exceptional staff at counter, gate, and on board. I haven’t travelled in US for a long time and was genuinely surprised how pleasant this was.

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

Trip was smooth bumpy from the wind but no issues at all the crew attendant was very pleasant and had great customer service

I liked everything about the flight. The service was excellent!

The customer service was excellent! Check-in, baggage check-in, boarding, the flight went very smooth.

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….

Nothing, terrible travel experience due to weather and maintenance delays and was left stranded in Austin.

Experience was bad. 3.5 hour delay for a 2.5 hour trip. There was no r Transparency about the reason for the delay and it was done 30 mins at a time.

Everything was great except for the wifi was junk. Crew was super friendly and helpful

The flight was short. However, my bag was delayed and was put on another flight.

Left from gate 30 minutes before flight. Never been late to a flight ever. It says 15 minutes before explicitly on the ticket.

Flight was cancelled had to move to another gate late again no internet paid for the month and never can use it waste of money

Flight delayed over an over all day until it cancelled at 1:30am. Would not repeatedly delay that late. Offer hotel rooms and rebook early. Very difficult for families with small children

Missed the flight because of them and up geting a rental car

Flight was fine. It took an unusually long time to have baggage delivered to the carousel in ORD.
