The staff were great and the layover times were excellent no multiple hours. I just hate the Boxed Water. So you really have to purchase high price water in the airport.

The staff were great and the layover times were excellent no multiple hours. I just hate the Boxed Water. So you really have to purchase high price water in the airport.

I like that we took off on time and arrived a bit early. I like that I could gate check my bag and board early. I don't like how crowded the flight was. I had ok leg room, but could feel every move of the person next to me. And the aisles are very narrow. The gate and flight crews were terrific.

I appreciated the ability to choose between multiple flights both into and out of Portland from Burbank on the same day, so we were able to attend an event and return without spending the night. I am unable to appreciate what Alaska Air calls "streamlining" the checkin/boarding process at Burbank Airport. If you have a smartphone and the Alaska Air app, it is probably fine, but removing the option of using onsite kiosks to print boarding passes does not meet my definition of "streamlined". I also found it challenging that both Portland and Burbank airports required the plane to sit on the runway for some time due to lack of an open gate at which to disembark. It would not be so bad if we could at least remove our seat belts and move a little bit while we waited, but that is not an option. I honestly don't know whether this is because of how Alaska Air operates, or just the circumstances of the particular day and airports we were using, but I normally do not experience these kinds of delays to reach a gate using Southwest Air.

It was not a great flight. There was a software update delay which had us on the ground for almost 2 hours. I was unable to make my shuttle to my final destination.

Both flights were delayed. We sat on the tarmac on Boise for 3 hours with little updates

This flight was significantly affected by poor wifi connections. I couldn’t get my work done because the wifi kept dropping. Even texts were not going through. There is no seat power in premium class either. I fly a lot. Today was my 10th flight in 4 weeks. This was by far the only flight that was sub par.

4 out of 4 flights cancelled or delayed. 5th trip with similar experience

the departure got delayed due to SJC situation, but it was a quite good waiting thanks to Alaska airline teams.

The flight attendant in the back of the plane was barely understood as she rushed through instructions to the point of being intelligible. She had a bored demeanor in her delivery.

On time, comfortable seats with plenty of leg room, nice staff. Pretty good!

Seat back monitors and outlets were dead and not working.

Everything was great except for the seat. The backrest would not stay in the upright position.

I usually have a positive experience with Delta. Complimentary upgrades are always nice!

Flight delayed about 2 hrs so it made it a VERY late night

The crew, food, and entertainment were all good. But my screen had some sort of bug where if I turned it off, it would turn back on after 2-5 minutes. At full brightness. It made it very hard to get any shut-eye on the overnight flight. Also, the older Boeing plane, while nicely cared for (and no doors fell off 😅👏) doesn't have the nice air quality of newer planes. So I felt a bit greasy by the time we landed in Sweden.

It was a crowded flight. They did the best they could.

Service was good for such a short flight. Small plane but smooth flight.

Worst flight in my life. Only was scheduled for a 45 min flight to get our connection flight. It was late by 40 minutes and we missed our connection. Delta was totally useless trying to help and unable to get my family on the next flight because they overbooked it Thus had to get a hotel at my expense and lost a day at Disney as a result. Cost me about a $1000 if you add 2 hotels meals shuttles etc to get thru the day Awful customer service by Delta in Detroit totally useless people

The experience was good and the flight departed on time and landed early

The flight was delayed but we got to our final destination.

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.

Hated every minute of it. This flight should have only taken 1.5hrs but was delayed over 10hours. Now I am being told I cannot be compensated or refunded my ticket price or extra leg room, which I purchased but did not receive, because the airline is throwing the blame on the 3rd party I purchased tickets through and 3rd party putting the blame on airline. No one wants to help. They received their money and that's all they care about. Im going on 3 days of still trying to get to my final destination, had to cancel car rental, car insurance and hotel. Currently staying in airport until hotels open up. Thank you Lufthansa, Kayak, Underpricer and United for making this trip the worst ever.

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

flight delays, staff only communicating when pushed, food service lasting a grand total of 7 minutes, stuck in seat from 45mins into flight until landing

Crew was great and did their best to make us comfortable and captain came out at the beginning to announce why the flight was delayed, weather situation up ahead, and kept us updated throughout the flight.

the flight from Tampa departed with a delay. The food on board was poor, usually on international airlines alcoholic beverages are offered free of charge , but here it was for a fee, the cutlery was wooden, there were no hot drinks (tea, coffee). Unfortunately, I didn't take pictures of the portions of food, but it wouldn't have been enough for a child either.And in the future, I will try not to use the services of this airline

they made me check my carryon. There was space in the overhead bins.

Nice flight, nice crew but no cookie or napkin with my seltzer.

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

This was a Lufthansa flight. Disappointing main meal. Very rough over Canada and arrival at FRA. IFE was almost unusable.

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

No problems with flight. Even though I had a short layover in DFW, I was still able to easily make my connection.

American Airlines continues to price it can provide the least comfortable passenger experience in the air. This legacy carrier rivals the budgets for both terrible seats and inadequate amenities. I am a 5’7” woman who is not wider than a coach seat (even on these narrow bodied aircraft). My 3.5 hour flight was terribly uncomfortable because the leg room is inadequate (my knees hit the seat on front of me even when it was not reclined); the seat barely reclines; and the foam padding is worn thin to the extent one can feel the metal supports of the seat. Add to this the fact that the aisle is super narrow, so that the drink cart literally scrapes the arm rest of the aisle seat. It’s basically torture.

Food options were limited which is absolutely embarrassing for a Flight of this size The staff did not come around as much and I am not accustomed to such poor service from American Airlines Drinks I believe were limited to soda and water

Plane took off without me, my stepdad and a dozen other passengers. It went from an hour delay to boarding in 15 montures without notifying anyone. Names were not called overhead. Now I’m missing a day of work and stuck in Charolette overnight paying for a hotel and Ubers out of pocket

I arrived to the airport 2 hours before my American Airlines flight was scheduled to take off. I have TSA pre-check. The airport was crazy packed when I arrived. After momentarily standing in the pre-check line, the TSA agent said that I am not pre-check. Of course I said that I am because I entered my KTN number on all my traveling sites and programs. I had to get out of line and go back to the AA counter to discover that American Airlines did not add my KTN to my boarding pass. I had to call TSA to find out my number, then have AA enter it onto my boarding pass. The emblem would not load onto my boarding pass. By this time, I decided to use my Clear in order to get through TSA but the line was ridiculous long. By the time I made through TSA, I missed my 11:08am flight and was re-booked for the 5:30pm. This is after the AA employee told me I should have gotten to the airport early. AA use to be a dependable airline not I use them only if I have too.

Average - flew with Jet Blue internal and it was far more comfortable and better food and entertainment. Notable difference

Flight from SBP to DFW 1. They rerouted us through PHX 2. Delayed flight out of SBP for 3 hrs so we missed our connection Downgrade on rerouted flight. Back of the plane, center seats, didn't sit together 4. Return flight out of DFW same exact thing. Delayed, missed connection, Downgrade + they lost our luggage! A complete mess.

On the new 319 NEO? seatback entertainment system did not work even when the flight attendant rebooted it. At least I had my cell phone to connect with wifi.

Good flights. Departure and arrivals were on time. DFW was a little problematic in that the Skytrain without prior notice bypassed the Echo terminal so that delayed my arrival at my connecting flight.

On time and fast. Overall it was a pleasant experience.

The weight limit per bag was really low - 40 lbs - so we had to pay extra. Then, they said their carry on size was 14x18x8, and we measured our bag very carefully. It was within the limit, yet they said it was too big, so we ended up paying an extra $100 for that too!! So it wasn’t the cheap flight we thought it would be. Then, they moved up our initial flight to depart 3 hours earlier which meant we had to be out on the road by 7 am and then have a 6 hour layover and we got home at 2am. It was a grueling day. I won’t be flying with them again.

Overall it was a good experience. Stewards were very kind and professional. The departure and arrival times were as promised. Plane was clean.

The seat are terrible. Don’t even think of sleeping on a Spirit flight. The kids that run the plane aka flight attendants are pretty rude and straight forward. They get the job done but without class.

No frills, limited comfort, no food, no entertainment, but fine

I had a death in my family and booked my flight on Spirit. My flight was cancelled the morning of my flight, no explanation, no help to rebook, nobody to talk to. The next available flight was 2days later !!!! Terrible airline, will NEVER fly with them again!

Flight was canceled. Knew there was weather, and were notified of 20 min delayed, and then suddenly canceled. Next reschedule was for 2 days. No help other than to refund. Thankfully full refund and appreciate that. I appreciate discounted airline but felt they could've done more for customer inconvenience.

The seat was very uncomfortable from Boston to Nashville. Otherwise the flight was excellent.

Terrible as usual!!!! Very unprofessional and rude flight attendants! You get what you pay for! HORRIBLE

There was a .79 discrepancy between the cost of the flight and what was paid. Spirit didn't let me obtain my boarding pass until the .79 (seventy nine cents) was paid. Contacting their customer service to resolve the issue was a nightmare that involved many wait minutes and two different departments. The price Kayak gave to Affirm, whom I used to pay for the tickets, and the price Spirit charged for the flight were off by the .79. I almost lost the ticket because of the hassle.
