Flight was awfully bumpy and landing was a bit jolting. I was in the restroom when snacks and drinks were served and was not asked if i wanted any. I had to ask for water finally.

Wi Fi was horrible kept cutting out the whole time and too expensive
I really like open seating. I hate that I've heard this is going away. This is one of the unique things that makes Southwest my goto choice.
Boarding was a little late, but made up for it. It was quick to taxi to the runway, since it's a smallish airport.
Excellent! Only question is how we check in at exactly 24 hours in advance and end up at the end of the B boarding group
Multiple delays and gate changes. Arrived at final destination 6 hours late. All rental cars had been taken.
Employees were kind and funny, as always! Flight was late but no announcements were made for people with tight connections to help them transition quickly. No service due to turbulence.
It was 2 hours 45 minutes late, for no apparently clear reason.
I recently flew Southwest from San Jose to Honolulu. I was very impressed with the flight crew, especially the flight attendant in charge of the front of the plane. She came through the aisle at least five times for drinks and water, and two times for snacks. I have not seen such service since I flew first class. Also, for the first time, they gave us the correct baggage claim number, and the luggage came out quickly. I can't wait for Southwest to have assigned seating! I absolutely hate the Cattle Call boarding procedure and the mad dash to get seats and overhead bins. However, the boarding was efficient.
Crew was great flight was great baggage claim was a failure. It took over 1 hour for bags to arrive. Poor communication poor effort when I spoke to the supervisor about the delay
Nothing! I just didn't eat or use entertainment. I had three seats all to myself and it was wonderful!!!!
The kiosk for check in/bag check in. I liked the older version where you did everything on the kiosk (check in and bag tags). This time I needed to use my phone to check in and then scan the ticket from my phone to complete the bag tags. I didn't care for this new method. The older method was simpler.
Weather caused delays, but since I was in no hurry I asked to reschedule for any other day to make room for anyone in need of keeping their schedule. Alaska accommodated my request with an extra bonus - with a credit to my account for another day…. Always had great experience with the Alaska folks.
Overall it was a good flight. No issues. Alaska Airlines is always my first choice.
On time (in fact, early). Easy boarding and getting off.
they took my carryon at the gate for free. Everything went smoothly.
It was delayed twice and they still want $8 for wifi so i had to sit for an hour.
I rated the food and entertainment as poor due to the fact the flights were short in duration and no food serves or entertainment provided.
It was awful. We experienced turbulence for nearly the whole flight. Then when I picked up my luggage, two of the wheels were torn off. Worst flight ever!!
I like the short flight to Seattle and San Francisco. The boarding was fairly easy and the flight was as to be expected. The in-flight entertainment could be improved with wifi options. Paying $8 and then losing internet access and being told that flight attendants didn't want to serve beverages and snacks on board was disappointing because they didn't want to move a cart up and down the aisle blaming it on air turbulence which wasn't a problem.
Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.
Flight left early and arrived early. the whole trip was excellent.
Seats were really tight and the seat belts did not give enough slack.
I like in St George and prefer to fly out of CDC than SGU. Hopefully, they will continue the flights out of Cedar
Broken jer bridge. Poor communication about it. Lost 2 of 4 luggage pieces
Overall, it was okay. Seat was a little cramped. Would’ve liked more substantial snacks or opportunity to buy some.
Inexpensive, got an exit row aisle aeat with no middle passenger, bought a great breakfast sandwich, flight comfortable & arrived ahead of schedule.
Delta was great the entertainment was outdated. Screen was very small and didn’t work.
The seats are uncomfortable, feels like a small seat pad on plywood.
My husband is very tall and we generally fly Delta Comfort. We used our companion benefit, and our seats were coach and extremely uncomfortable........ horrid even
My seat was very worn. Otherwise I had an excellent flight
Boarding can be more efficiently done by having the back row passengers board first. This way, the other people do the have to wait for front row passengers to load their luggage in the overhead cabins. Food is simply pathetic for the price I paid. Cleanliness is simply poor; my seat was full of crumps.
Always a great flight on AA. PHX to DFW and vise versa is always going to be a pretty full flight but the crew handles it phenomenally.
also wi-fi never worked attendant said satellite coverage is spotty over water ..... but we were over land!
The main problem was delay. The plane was at the gate early and bags were loaded. However, there was no crew for the flight. They were inbound from LGA and had to land and make their way to our gate. It took more than 40 minutes. Then, once the crew arrived and boarded, one of the crew members had to deplane and then a replacement crew member had to be found. It took another 40 minutes or so to get the final crew member. In all, we took off about 2 hours later than our scheduled departure time. Once in the air, the flight was great. Smooth most of the way. The crew was professional and efficient.
16 Hours delayed, NOT because of the cybersecurity Microsoft issue, but because we were one flight attendant short, then when the missing flight attendant showed up two hours later, the flying shift of our pilot had expired, so, now no pilot. American Airlines is the new Spirit Airlines, actually, that is not fair for Spirit, they are probably better.
Worst flight in terms of service and food. Attendants were inexperienced, no preflight drinks, did come and give us hot towels until well into the flight. The left the Curtin open between main cabin and everyone from the main cabin went to the fist class bathroom. Food was awful! Had the golden chicken and was too lemony and inedible. No offer of coffee after. Awful!
My morning PHX to NY flight was canceled. Not a cloud in the sky. No wind. No weather across the country. My guess is they canceled the flight because they didn’t have enough people or a mechanical issue. Either way really bad. I checked it at midnight and the 830a flight was on time so I was very surprised when I woke up to see the flight canceled and I’ve been rebooked on a flight… An hour earlier than my originally scheduled one. Of course I missed this earlier flight because AA texted at 4 AM when I was sleeping. I was re routed to Miami, boarded a plane, sat in the heat for 40 minutes, then boarded because of mechanical issues and had to wait another hour before finally getting to New York Ironically, the 430 Phoenix to New York flight landed at the same time I did… I could’ve been sitting at the pool all day vs jumping through hoops. never ever will I again fly American Airlines. No offer of a free drink, maybe a few points on my advantage account nothing… As if nothing happened and they did not inconvenienced me at all. I’m so sick of the dumb crackers that they give us on these flights. It’s really like a budget Airlines these days. A far fall for s once mighty company.
Delayed by over 4 hrs, missed all international connections. Horrible customer service.
They took away my first class ticket for my plane ride from Ickx to Tucson because they’re plane was late getting there. They offered me nothing in return
My experience with the phoenix airport was terrible, the personnel lay the ticket counter charged me for a carry on that fit in the carry on size box, and the two women I spoke with were terribly rude and not willing to help.,,, there was one lady “candy” on the flight crew that was amazing and is the only reason I stayed on the flight at all, because the other stewards helping people to get seated on the plane were terrible
I loked walking out on the tarmac to board and no first class. I didn't like that they have no snacks or onboard wifi to bide your time.
The plane was clean, the crew was friendly and helpful. It’s a low cost airline so there was no food, drinks or in flight entertainment but we didn’t expect any of these things. In the room for improvement department, they should install USB ports in seats to charge mobile devices.
The seats were extremely hard and uncomfortable, even for a budget airline.
The seats were extremely hard and uncomfortable. It was disappointing even for a budget airline.
Charging $74 for one checked bag is outrageous. I will never fly Frontier again.
Boarding was very well executed. Got my bag right away.
I was surprised that all baggage, including carry on, were charged. Each additional bag went up in cost. Really disappointed in the additional costs.
Our flight was suppose to leave at 9pm and we didn’t board until after 3am. We lost a whole day at our hotel and half a day at a park we paid a lot of money for.
It was a redeye flight, so every passenger just wanted to sleep, but through the entire flight, the flight crew made announcements over the loudspeaker at maximum volume every few minutes making sleep impossible. For example: it’s 2am, and the crew decides to give an extremely detailed announcement about snacks and beverages for sale. And 3am is the perfect time to wake up everyone with a lengthy announcement about how to get a coffee refill and how to take advantage of new offer from frontier for a credit card.
