It was good. Last flight was delayed but I always say that is in God's plan

It was just okay, no frills, basic transportation with no luxury. No screens on the seats, no water or drinks on a short flight. Full flight but at least it was on time.

Plane was clean and comfortable. Flight attendants and gate staff were professional, friendly and efficient. Boarding and deplaning were orderly and efficient. All in all, the typical excellent Southwest experience.

The seat was not comfortable. 1D. My back was sore all night and the next day.

The new boarding process was easy and straightforward. Very pleasant.

It was as expected and I was grateful for the wheel chair help and ease of use.

No food or entertainment, just a quick 40 minute flight. A little bumpy due to Santa Ana winds but pilot has no control over that. Good flight and landing!

WiFi did not work. Boarding with the new seating assignments took too long. The temperature in the terminal was obnoxious. +/- 80°

Paid for premium extra leg room but the bin space for rows 1-3 had to go in rows 4-6 and 4-6 had to go to 7-9 because flight attendants have snacks and their luggage upfront. So we pay extra to have to fight thru traffic to get our bags. Only 2nd day of new seating so hope they fix this.

C Am handicapped and couldn't get help with my luggage.

Delta is always a wonderful experience. A clean plane and the crew is really friendly.

Air travel sucks. It continues to be awful for all airlines. No shame on delta alone.

Everything went well and was good. Nothing exceptional, but no complaints either. Cheap seats are pretty comfortable.

De planning was an absolute mess. We were never told that we weren’t at the gate and that we had to go down unstable stairs and then hop on a bus. People were falling, we couldn’t tell who was in charge. Overall terrible communication that ended up leaving a bad impression at the very end of the experience.

Great overall. There was a bit of turbulence so they could only serve water because too much turbulence for the carts. Was glad they prioritized safety though

Long line to check bags. Curbside check-in was closed. Seat back monitor was not working.

Left on time. Arrived on time. That’s all i ask.

AC barely worked on a 50 minute flight. It was very warm the whole flight. Flight was very bumpy and hard landing.

Everything was very good other than I had selected a specific seat when I booked the flight and they changed it once I checked-in the day before my flight. I was still in first class but lost my aisle seat for a window seat. Being tall, the aisle offers more comfort so I always select an aisle seat.

We flew early evening on New Year's Eve. Our plane was less than half full... Great for the passenger experience -- not so much for the airline lol. Comfortable, spacious, smooth flight -- and early arrival!

We had to wait almost an hour for the wheelchair porter to be ready to pick up my mother. And when she arrived in Newark airport the porter was not there and she started walking with her cane and her poor mobility. When the Newark porter found her they didn't want to transfer her bags to the wheelchair for her.

Delays from united along with Newark air space caused delays. But an average flight! Unfortunately we come to expect delays from the airlines.

Fast checkin with the self serve terminal, good communication at the boarding gate.

The plane’s radio wasn’t working. This delayed the plane for an hour and a half. Then we all broaded and taxied down the runway only to get called back because the radio was still not working. Had to get off the plane and then find another plane making the trip 4 hours delayed. Maybe a different plane should have been chosen sooner?!?!?!

Flight was 3 1/2 hour delayed with no credit or meal vouchers

The plane was so gross and dirty. Literally saw dust layering and flowing out the grey vents. Dust was all over the air vent knobs to the point where I took my sani wipe and cleaned them down so at least it wasn't blowing my my face. Also, I upgraded and paid for Wifi and it's always so spotty. I get we are in the air, but don't charge for it if it's not going to work. I expect so much more from United. They really are giving up.

Too many canceled flights and kept my wife and I separated on alternate flights. We did not fly out of Denver. We paid a lot of money for the seats we wanted and now that money is gone and we did not sit together. That being said, the many agents were very friendly and did everything possible to help us.

It was soooo hot I was sweating even at altitude. I know you want people to sleep, but keeping it that hot is stupid!

The Flight was good, pilot seemed very skillful. My wheel chair sister who could barely walk was allotted the second last seat in the aircraft, with great difficulty she managed to reach on her seat, as she required attendance we were given separate seat, even on request no one cared, so much so there were single passengers who were given twin seats. May not be taken as complaint but a reminder to the checkin staff to keep in mind in future the allottment of wheel chair passengers seats.

For each flight from Key West to Fort Lauderdale to Newark to Buffalo there were at least three delays at each leg of our trip. We were due to arrive home @11:37 but finally arrived @2:25 AM costing us an extra day at the car park. Seats are uncomfortable resulting in need to seek chiropractic care for backache. Upon deplaning my husband discovered someone had taken his clearly identified carryon from the overhead bin. I will not plan on flying again soon and not on United.

Terrible boarding and first class experience. Nice staff but overall disorganized, dirty plane.

weather delay of almost 2 hours then we landed and our gate wasn't available so we waited another 30 min

We got delayed getting out of DFW for broken overhead bins. Once the flight got underway the captain kept the seatbelt sign lit the entire flight despite little perceptible turbulence, preventing use of the rest rooms and any sort of refreshment service in the main cabin.

I almost missed my flight and they helped me out enormously

It's very confusing because Kayak has it as American Airlines, but it was Hawaiian Airlines, but operated by Alaska Airlines. I had to go to the airport for my boarding pass because American said I didn't have any trips.

The boarding was pretty easy. However, the first class seats are not lay flat as other airlines (like JetBlue) has and therefore sleeping was a challenge.

Between Las Vegas and Dallas was okay But, once in the Dallas airport, notice, I have disability and ask for a wheelchair, they leave in a middle of nowhere, the personal in charge try to push me on a cart where I couldn't sit because was to high. Then they don't care about me, they bulling, till I start to yelling and crying, ask to everyone around, who can help me. The man in charge make a despective movements and said you are to loosing the fly. The last name in his batch started with an H, I did not have the full name. A nightmare. After all, a woman in charge was walking very slowly and asking me for a tip cause she was helping me to reach the fly. For years, AA has been the preferred airline. The personal in charge of the disabled people are discriminate me. Thank you Kayak.

Customer service in first class does not exist on American Airlines

I love to flight american however my carry on had to be sent with regular luggage and it was broken. Don't appreciate that. If when I buy a ticket says I can take a carry on and a hand item there should be space for mwsy stuff and not be basically forced to send the item even if it's at no charge. A.A. needs to work on that. Everything else excellent.

We liked quick boarding and on time departure. Seats were very uncomfortable.

Tiny seats, no entertainment, no amenities, delays, they charge for carry on and their allowed personal item is smaller than in other airlines.

Frontier.. nickel and dime add-ons. Flight late, on time, late again, last minute gate change, arrival gate required a shuttle to the terminal. They sure keep you guessing.. if you like a little chaos and airport anxiety, this is the airline for you!

baggage clamed had to wait over a hour and half for all people on my flight it was terrible

Both legs of the flight were changed. The day of the flight and length of the trip.

food not having to pay for it, reclining seat would be nice, more leg room, HEAT!!!!!!!

Very easy with the app to board and staff skills

Delayed for two hours due to trivial issues. No reimbursment. Also on arrival further delay due to terminal malfunction.

Did not realize seats did not recline. Best to travel in an exit row... No question

First time flying with Frontier . From buying tickets ,getting boarding pass and boarding plane was super easy. Definitely would fly again with Frontier .

The only thing that may be concerning to others is the multiple notifications of a delayed flight. Then, with less than an hour before boarding, the flight was on time. The gate changed several times, leading to confusion.
