My first flight was delayed by over an hour, luckily I had Long layovers on an itinerary from hell, because when you book a Saver ticket, they change your itinerary and make it many stops and long layovers, and there were still delays. On the return flight there was a delay in the first leg, Orlando to Seattle, so I got up really early for nothing, and on the last leg Anchorage to Fairbanks, it was over 2 hours late taking off! I didn't get home until 1 :30am! By the time I got my luggage, the flight landed at 1 am. For the departure day, I was up from 6am to when I arrived the next day at 6am in Orlando. So I was up for 22 hours, 3:15am to almost 2 am the next day. On the return day. The moral of the story is, DON"T EVER BUY SAVER TICKETS! You can't even upgrade your seat when you do that and then at the last minute they want Big bucks to upgrade the day before leaving.

I had the worst seat neighbors thry literally snored so loud and the man next to me man spreaded the whole time i couldnt sleep
Service was great! 👍 Seats were small and absolutely not enough leg and feet room!!!
We sat on the tarmac for so long when we got to SeaTac that half the plane missed their connections.
Packed flight, cabin was so hot and stuffy that a woman fainted in the aisle. Crew were so inattentive that it took a awhile for just 1 Crew member to respond. Seat was incredibly cramped. Made to check bag because of "no overhead room" but there was plenty of overhead space when I was one of the last to board. Why is someone in boarding class A-D entitled to carry-on space but people in class E-F aren't? Whole flight was very uncomfortable. Shitty flight with a shitty airline. No more Alaska airlines for me.
The boarding was quick, but the cabin was uncomfortable and I got stuck in the galley while the flight attendants handed out drinks after using the lavatory.
I understand it’s their right, but when two of my party missed the flight after checking in it seemed insensitive to cancel all of their subsequent flights and for us to lose the extra seating despite having paid for it @ the very least we could’ve been refunded for the checked bags that we prepaid for and never used.
Great. Went right to the desk and the people were helpful and kind. I was able to get my boarding pass in under 5minutes. They made sure I received the text.
In evening be nice to have something sweet rather than dry pretzels
Poor, no one with Alaska Airlines is in a hurry to do anything. Slow, lack of intent, inconsistent.
I really liked the legroom. I am 6’4”.a at For some reason our seats were not together and using the app to fix it didn’t work. Passengers were nice enough to move for us but you should absolutely ensure a parent sits with their child.
This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.
Did not realize internet screen was hidden between seats and no info printed!!!!
2 of the seats in row 31 the entertainment system was not working, and one seat the tray table did not go all the way down. Flight arrived early and departed on time which was great.
I noticed that the planes seem to be outdated. There was no entertainment per se. Also, the waiting area did not have any working electrical outlets
Service in business class was not impressive. I ordered coffee with dinner and then watched other people get 2 refills before I got my 1 cup of coffee, and only after I pressed the attendant button overhead. Furthermore, the seats in the forward cabin need maintenance on this 737-800: the upholstery is detaching from the seat frame, at least on the backs of seats 1C, 1D.
Our flight attendant in FIRST CLASS was one of the worst I’ve ever had. She was not at all pleasant, nor particularly good at her service.
DELTA does a terrific job making sure you are well taken care of during the flight, gives you assurance before the flight through numerous email notifications about your upcoming flight & lastly good follow up after the flight making sure your needs were mat. It has been, is & will continue to be my carrier of choice in all my future travels. Good Job DELTA
The customer service before board was very rude and when I expressed my concerns about making the connecting flight she laughed and told me I bought the wrong ticket. I explained once it showed the flight was delayed it no longer let me change seats or anything. I was trying to upgrade to make sure I would get to the next gate on time.
They changed planes and the new plane couldn’t carry enough fuel to fly across the country so we had to stop in Kansas City to refuel. Flight was delayed .
The crew at Hawaiian Airlines was fantastic. Kind and hard working. The pilots were great with giving us all the updates to make sure we were informed.
Very good. Nice plane and we sat in economy plus - bigger seats, more room. They served a meal and snacks, and the meal was an apple stuffed pancake that was very good! The snack for us was a hummus sandwich - also very good. The flight attendants were helpful and nice. They have plenty of movies and shows to watch. My only negative -- they changed our flights around and did not adjust the layovers, so we ended up with a very long and unnecessary layover in Honolulu.
I liked the Starlink WiFi but didn't like how they said they were the only airline to offer a free meal and it turns out to be just a standalone sandwich and then charge for snacks to go with it. Rather have the free snacks like Southwest, but have the option to purchase a decent meal for a 5+ hour flight.
Flight scheduled to take off at 5.55pm but it did not take off until 7pm due to some food delivery delay.
Unfortunately, I was put into the middle seat in the first row of premium seating. Sounds nice right? No! that is the worst seat in the plane. I wish I was in economy rather than be in that seat! There is no seat back pocket, no tray table, no charger. Nothing! so unless you're row mates are willing to let you share their basic amenities any flyer should have, you are stuck. It was the worst experience ever! And the flight attendant forgot to take my drink order. I felt like the forgotten flyer.
Delayed and cancelled flights were hard and very stressful, both ways!
The crew was quite good, they came by often with drinks or to collect trash. But what wasn't nice was the flight was over weigh and several people had to be rebooked. I was questioned whether I should have a seat when I was getting to it. The in-flight entertainment kept buffering and interrupting. And the route took the airplane through high winds which caused us a longer flight
Wasn’t on the flight due to Alaska cancellation…also after all the rerouting, I was going to be on a later flight that left SFO at 7:47pm, which meant an almost 6 hour layover. That same Hawaiian flight was delayed for another 2hours.
I had to cancel the flight because with a 3 hour delay for 'unexpected maintenance' in getting to LAX, I couldn't connect to an overseas flight that I had booked on Scandinavian Air.
The flight was CANCELED!!! Can’t get much more “poor” than that. I had to switch to American Airlines, add another layover and got home in Honolulu 4 hours later than I was supposed to be home. One bright spot was Josh with Alaska Airlines at SFO. He got me on a United Flight that got me home a few hours before I would have. Without him I would have gotten home almost 7 hours after my originally scheduled flight.
It was fine. My connection in Charlotte to go to WPB was too late and I had to spend the night in the Charlotte Airport in the mini suites.
The flight was on time and arrived early. The crew were friendly and helpful.
My carry on baggage was damaged. Entire trip, I had to carry the baggage. When complained to the boarding crew, they got mad at me and still asked me to valet check in the cabin baggage. Rude boarding crew!!!
Everything about the flight was lovely. My only suggestion would be to offer a few more options of tv series from Apple TV or HBO.
Nothing to write home about, average flight experience. Seats were spacious enough, crew friendly enough. Loved the AA entertainment/wifi service.
Kayak was among the missing. There was not the usual advice regarding next gate after arriving in Dallas. No communication after the reminder to check in before the Moline flight. What happened?
They should have allowed for extra time to de-ice the plane before boarding passengers. This delayed us about 10-15 mins after we boarded. Overall experience was fine. Crew was friendly and on top of everything. We didn’t have any issues during the flight.
Experience was good. We were delayed in leaving by 15 mins because the flight was waiting on a family that was late in getting to the gate. Food and drink options were as expected. I highly recommend checking in ahead of time using the airline’s app so that it’s quicker to get your luggage tags as soon as you arrive at the terminal. No more waiting in long lines!
Overall experience was great. Flights were almost on time in departing and we arrived at our destination as scheduled. No issues with amenities or flight crew. Everything went well as as expected. Will fly again with American Airlines in the future!
We never made it due to delays on both ends. Gate attendant said it was mechanical but the system said otherwise, so no compensation. That’s not right.
1) No pilot available for 1 hour 2) no room for most passengers careyon in overhead—-> stowed below 3) when we landed we had to wait 45 min. Before docking at gate as gate was not ready
It was good. I prefer JB over other airlines.I just wish we had headphones for the films, but other than that - good.
The ride share experience in JFK is terrible. After traveling on a flight, then you need to take a subway to the last stop to get an uber or lyft. Unacceptable. Bad job JetBlue for permitting JFK and Port Authority to do this to your passengers.
Checking In on JetBlue site was impossible. It hung up on REAL ID. Even my Global Entry did not help. Luckily, on Kayak site it was a breeze. Entire flight the temperature was COLD! Otherwise the crew was great!
The flight was two hours late due to a computer fault and resulting maintenance. Nothing was offered as compensation beyond bottles of water during the time we were deplaned and waiting in the terminal.
Very pleasant flight attendants. Gate crew rather loud chatting with each other.
Four plus hour flight delay in New York caused us to take off after 11:30pm. We didn’t arrive at our hotel until five hours after check in. Started the trip off feeling exhausted.
Plane was in bad shape. TV’s and WiFi didn’t work. Plane need a refresh. Not enough room for bags.
Everything was great. I liked the text updates so that I never miss a gate change & I have all the latest info.
I don’t usually fly budget airlines or airlines in the United States. It was as good as any other airline. The seats are comfortable and the airline attendants are not rude & surly. Very nice flight (s).
