we were late due to plane's late arrival at the gate and then there was a glitch with a button or something that had to be fixed and we waited for a tech to do that . The flight was very bumpy and totally not anything to do with the plane or crew. Just saying what was a bit miserable and kind of worrisome give then recent circumstances with the planes. Nothing fell off or onto anything during the flight of take off and landing so I count myself lucky to have gotten to my destination there and back safely. Thank you for asking

I'm a tall guy. Fortunately I was able to find seating in the emergency rows that gave me a couple more inches of room. My return flight a few days later, I wasn't as fortunate. Very painfully and uncomfortable return flight.

Flight was smooth but to many screaming and crying young toddlers who wouldn't stop crying and screaming at the top of there lungs it gave me a bad headache.

They misplaced our 1 bag and that messed up our reservation for the following day of fun and we paid extra 100 for the bag. Not fun

Crew was friendly and professional. Offered multiple drink services. Handled this full flight with style and grace.

Horrible, missed my connecting flight because Alaska did not give me enough time

Great crew. Uncomfortable cramped seats. Crappy snacks. But on schedule and no doors blew off.

Everything was great until one of my 4 checked bags didn’t make it with me. Baggage staff at OAK were not especially congenial the first night. Got my phone number wrong so they couldn’t reach me via phone. I was able to pick my bag up within about an hour of when I initially wanted to. Wendy was very helpful.

I was on a ski vacation and traveled between Pittsburgh and Big Sky, Montana via Seattle I was very disappointed that I couldn't reserve a seat between Seattle and Big Sky ahead of time and angry that I had to pay a fee to get a seat (both ways) when I checked in online. Why couldn't I select a seat ahead of time for that leg of the fight? The flight itself was fine and the seat was comfortable. On arrival back in Pittsburgh, I waited over an hour for my skis to arrive after I retrieved by boot bag from the carousel. This was my first experience on Alaska Airline and it was disappointing.

One of their flight attendants made a rude comment as I deboarded the plane. Definitely won’t be flying with them again.

Standard economy seats on Deltas 767 were better than Alaska premium seats on their 737 MAX9; more legroom, wider seats. Entertainment was great, no ipad or phone required. Could have included a meal service.

Plane was turned around due to fog half way into the flight, Delta did not properly direct passengers to stay on same flight and instead failed to properly rebook on Alaska

The boarding process was terrible especially with an indirect flight Chicago to Seattle to San Diego was terrible talking about we overbooked a flight idk if I’d take this airline ever again we got off our flight from Chicago to Seattle and we traveled for business and they told us our connecting flight was over booked and their was no seats asking people to take a delayed next flight and they don’t tell anyone coughing to wear masks seats 30A-B were terrible during the flight no one wants to sit next to people coughing all around I don’t want to be sick traveling for work or get sick anytime it’s very upsetting the staff doesn’t take this stuff serious to tell them to wear masks when they see people coughing and sneezing

Flight was on time, the crew was personable & professional, & the plane arrived early which was nice.

This flight landed early, but deplaned late. We were stuck sitting and waiting for a gate for over an hour

My flight was very clean and the location was comfortable. The service was great. A satisfying flight!

Really liked the choice of the 4 free snack options. Crew great. Good vibe on plane.

More filling food and more entertainment options would be cool.

There was no wifi even after my husband paid for wifi it wasn’t working. The plane looked and felt old.

Flight and seats were great. Food service was average at best. The real main problem we had is that we got cheeseburgers for the kids but the plates was extremely hot. Like ridiculously hot and the stewardess never said anything. Luckily or unluckily my wife touched the plate and was able to deal with it before the kids got burned.

I was not able to buy food in the flight. They refer to include your Credit card in the APP, and if you are not from USA (i have a credit card form Canada) it is not possible

The flight from Ottawa to Chicago took a lot longer due to DC in Ottawa. We got to Chicago and went to our gate to catch our flight. We only had nine minutes I found that very stressful.

Good boarding. Crew started quick with drinks and food. They came around several times for trash which I really liked. Other than turbulence due to storms in the area, flight was great.

The control panel for the seat back screen did not work at all after takeoff.

Our flight was delayed many times throughout the day. The final delay was about 8 hours. I spent time in line to speak to someone at their understaffed desk, and also spent time waiting online and then chatting with a service rep. None of the United employees were any help at all. I desperately wanted to go get rest and possibly re-book my trip but I was denied any compensation or voucher for a hotel. I was repeatedly told it was not United's fault and therefore they had no compensation to offer. Overall, a cold and callous experience.

Flight crew and pilots did great. Flight way delayed due to a part needing replacement. Based on what the pilot indicated- the maintenance crew could’ve resolved this more efficiently than replacing whole part- and taken less time

Plane was so old it had cigarette butt trays in the seat

Everything was good, hard to really comfortable on a flight that long.

Unfortunately our flight was delayed by 45 minutes due to Kate arriving aircraft. Once we stated everything was great.

For some strange reason I was put in zone 5 for boarding even though I had paid premium price for a premium seat right behind business class. This must have been a flaw because everyone else around me in the same zone (row) had been placed in zone 3.

I had trouble finding a boarding pass because I had an hour between Flights and American did not see my flight I believe because I was ticketed through KAYAK. I did not have enough time to go to the desk before boarding so I went to the desk and told them while I was boarding and they had a boarding pass for me within three minutes. Nice. I paid extra to have more legroom and it is definitely worth it for a six hour flight. I would’ve paid for a decent dinner, but they didn’t offer anything but a snack box —not good for six hours.

5 hour flight - full flight - not enough room to use my computer - slightly delayed - Admirals club was excellent quality food, drink made up for flight seating. No food offerred on flight, you ahd to prebook.

Excellent- plan was barely populated. I cannot remember a flight where I was able/encouraged to stretch out!

Great flight. Boarding was efficient and quick. On time departure and smooth flight. Flight arrived early at destination. Good experience.

Had technical issue which delayed the flight period. Flight crew knew there was 5 passengers that the connecting flight was within 15 minutes once at the gate. Rather than identify the 5 passengers to assure they got first. The flight attended mentioned it but didn't assist to assure passengers with connecting flights off first. This caused a hardship and our party of 3 missed the connecting flight.

I don't like that I have to pay if I want extra leg room. The seats are so expensive; I sit in normal seats and my legs and knees cramp the entire flight. I never feel comfortable on AA flights.

Terrible flight seats where really uncomfortable I had body aches for 2 days and flight was delays almost two hours

Flight was delayed at departure due to weather and the need for de-icing. The flight was smooth but there was a delay at arrival due to weather. We were in a hold for 20 minutes or more. The flight arrived more than 30 minutes late. Airlines have no control over the weather and I'm glad that they follow all safety procedures. Had to wait a long time for my checked luggage. Whole process was slow and the bags arrived wet due to the rain. The onboard wifi and entertainment access was spotty and the signal was dropped several times. Otherwise the crew was great and friendly. They tried to get everyone's bags stowed and seated so we could take off.

Regarding the boarding: it needs more efforts to make it more convenient

Deicing in Denver took forever and I almost missed my connection. De-ice faster! Not Americans fault.

Delayed...attendants checked every single bag and item for sizes before boarding.

There was no wifi, there was no usb charger on the planes Frontier lowered the weight limit on suitcases from 50 to 40 pounds Frontier now charges for a seat...really? If i don't pay for a basic seat, do i stand the whole flight? Frontier now charges for the carry on, just like for the checked suitcase The bundle pricing is way over priced.

I am HIGHLY unhappy with the amount of money I spent on the flight. Paid in advance only to find the flight at a discount price a week or so before the flight. I will not fly frontier again and have bad mouthed your business since to anyone I have spoken with about flying (which has been many a people). Crew was mediocre and instead of moving me to a spot where I could gain some leg room they sat their flight attendant there. Won’t be flying frontier in the future.

They changed my flight and did not want to accommodate me or try to help me in any way. They do not care about their customers.

Plane was clean but they do not allow bag drop until 1 hour before flight. Just encouraging late fees and other issues. The worst I have experienced. Total hostage situation, pay or you miss your flight.

Everything was good, 20/30 minutes late waiting on a crew member. It’s hard to keep employees. Or serious employees I know. I remember one flight from Houston of Frontiers was almost 18 hours late. And another 4 hours late very poor. But I would rather be late and safe than the on the news. Thank you.

Well, I didn’t have food! So NA wasn’t an option. I’ll be back!

Bought seats on the flight and they were supposed to be 2 and a jumpseat. Plane clearly changed and it was a regular 3 seat row. Asked for a refund and was denied. If I wanted to sit next to someone else I wouldn't have bought the seats..

I dunno. Depressing, uncomfortable (I’m poor), but on time and efficient.

Everything was good, and most importantly on time. They have been extremely tardy in some of my flights
