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.

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

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

I did not like anything about that flight. The check in at the gate was horrible. The inflight service was bad and WiFi was not available for me to be able to entertain myself since it was a long flight.

Becoming shittier by the day. Spirit airlines was way better and gave better value for money.

I asked to be moved near the bathroom due to kidney issues. The gate agent was very kind and did that for me.

The seat side plug ins didn’t work in my row, and I ran out of things to do since my iPad and iPhone ran out of juice. The flight attendant offered me a free drink but I don’t drink. I suggested a free snack box instead and she just shrugged and walked off. Why do us non-drinkers get the short end of the stick?

The flight crew was super friendly. All flights were on-time. Everything went smoothly!

It was a Red-Eye flight so was not comfortable enough to sleep, but seat was as expected. Crew was great and in-flight entertainment was excellent. Flight was smooth

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!

I appreciated being upgraded. I was very disappointed with my 13 hr layover in Seattle to geg, while my friends who flew Alaska made it home as scheduled. I had to reserve a hotel on my dime.

Delta needs to step up the meals and snacks. They have been serving the same two meals for three years.... It is time to change it up.

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

I just wrote a text which was supposed to be for the flight from Denver to spokane not Frankfurt to Denver.

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.

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.

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.

It got me where I needed it to; not much more. It had no competition so that was why I chose it.

Comfort of seats, ease of boarding. Food selection could be better

i suspect i caught flu on this flight as i could hear someone coughing a few rows back and ended up with flu a few days later. also tiresome to have to watch movies on my device by holding up smartphone screen, would have liked to have in seat display.

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.

A flight attendant appeared to not be in a good mood that served us; felt she was being short. Overhead announcements were very loud compared to other airlines and the message was not friendly and was a little confusing. This flight was particularly over all was not satisfying compared to previous Sun Country flights.

Airlines should have to add their fees to their fares

I am upset with the hidden fees for bringing on an overhead carryon onto flight and also having to pay for my seat selection. This should all be part of the original price of the ticket. Very poor customer service

Sun country Wi-Fi was not working. Flight was overbooked by two people. Had to pay extra for carryons day before flight and I don’t like hidden fees like that.

WiFi did not work. Woman flight attendant in the rear of the plane was moody.

Flight delayed over 3 hrs due to unexplained issue. No text message to notify.

Well we did not realize at first it was a ground transfer, but we really enjoyed it and would definitely recommend to friends and family. Our driver was awesome and the ride was wonderful. A bathroom on board would have been nice, but at least we were warned that there wasn't one so we went ahead of time.

We were on a fairly long flight and they offered nothing for a snack (unless you paid) and then quickly gave you a drink and were never to be seen again. I would have loved a refill on my water but that was not an option. The flight attendants were standing on ther phone when we boarded and left and never even greeted us. Any other flight I have been on they would have welcomed us on the plane and again greeted us as we got off. Our landline transfer from MSP to Rochester on the other hand was FANTASTIC! We would highly recommend!

Took forever to get the plane loaded and unloaded. Longest I have ever had. I was in the middle of the plane and it almost took a hour after landing to get off of the plane.

Our flight was delayed and there was no communication at the airport.
