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!

I am an avid customer to Alaska Airlines and I was so disappointed with my flight experience on flight 639 with service from Phoenix to Seattle. This flight was supposed to take off at 7am. We sat on the airplane for an hour before we had to deplane due to a mechanical issue, which is fine. The agents working at the desk let us know that they would update us every 30 minutes with new information about our flight and that at the moment they were only helping customers who, due to the delay, would miss their connecting flights in Seattle, which was understandable. 1.5 hours went by before we got our first update of “unfortunately there is no update” finally, after 3 hours of waiting with hardly any update, I got in line with the rest of the passengers to figure out my next move due to the fact that I was supposed to be at a wedding that night and that I had spent a lot of money to make that morning flight. After sitting in line for over an hour to get help, I decided to call customer service to see if they could help me rebook a flight just in case, to which the agent said she could rebook me for a flight at 3:31pm that had 3 seats left on the flight. So I took it with the hopes that I would at least make the dinner portion of the wedding. I spoke to the gate agent and asked how I could retrieve my bags and he said they will be moved over to my new flight (2 gates down). Finally after being at the airport for 10 hours, it was time for me to hop on my new flight before I came to find out that I was on the standby list after being told that I had 1 of 3 seats that were left. I went and talked to the new agent to which he said, “yeah sorry there was a family who was after you on the waitlist so we gave them priority, so now there are 3 people ahead of you so you may actually not get on this flight.” All I could think about was how frustrated I was that I paid over $400 for a flight to get told that I may not make it home anytime soon. Finally, somehow a kind person gave up their seat for me to get on with compensation for him. When I mentioned that I had been at the airport since 5am (10+ hours) verbatim the gate agent said, “yeah that sucks, but it happens” absolutely no sympathy or support whatsoever. I then asked about my bag and if it was moved to this flight and the gate agent told me “they may not have had time to move it over so you might not get your bags today” so from my understanding from 11am when I changed my flight until 3:31pm my bag didn’t have time to move two gates? That seems ridiculous. Luckily I checked my app and it showed that it was moved. It was a long day of terrible customer service, no updates for new flights, long wait times, no compensation besides $12 for food that I didn’t even receive to my email until I landed in Seattle, having to wait 35 minutes for my bag at baggage claim upon my arrival in Washington, all to miss a wedding that I should have been a huge part of. So disappointing for someone who religiously flies with Alaska and has 4 or 5 more trips over the next few months with the airline and not a single dollar or mile returned for poor service.

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.

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.

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.

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.

Do not eat the bagel! Otherwise, good albeit late, breakfast in first. Boarding downgrade only because flight was delayed due to plane change due to undisclosed problem with original aircraft. I did not use entertainment.

Because I can’t stand very long in one place, I was allowed to reword.

Not have to pay for every single item to take a flight. Seating and delays sucked.

Flight was cancelled and I had to spend the night in the airport lugging my suitcase around

If you don’t check in 24 hours in advance, they will charge you $110 to check your bag instead of the $30. I did not get an email with this information and did not check in. In addition, my flight home was cancelled at layover and I had to spend the night in the airport, and then have another layover at another airport before making it home. Will not fly frontier again.

Terrible. Seats are bad and the baggage policy is inconsistent

Flight delayed 3 times, resulting in late arrival, rental car place gave car away resulting in increased BS charges because I was late. Frontier blows.

I paid for extra leg room. The flimsy plastic seat underneath the floatation seat did not line up with the arm rests. It seemed as if the plastic part was zip tied on but immovable. This caused severe uncomfortable for the duration of the flight.

Left Denver late, then sat on tarmac 30 min after arrival

Better than I expected but I did pay for a seat and carry on bags ahead of time.

Crew members are very rude and not cooperate with passengers.

30 minute delay due to boarding and settling of a family.
