The entire experience from boarding to landing was amazing! The crew were very friendly. Will definitely be back.

Delayed flight, lack of information, boarding process is a mess as is the carryon luggage causing issues when leaving the plane….just a poor experience.

Great flight from Seattle to Phoenix and to Chicago-Midway from Phoenix

It was good from LAX to Phoenix, But the connection in Phoenix to Tulsa was not that great. The staff on both flights were great. The choice of free entertainment was ok nothing to brag about. The 45 min delay because of some electrical issue wasn't great from Phoenix to Tulsa. We sat there with hardly any air, The seat I had was between windows so the side of the plane pushed in on you. My being a bigger man it then made the seating area uncomfortable. The seats on the plane had no power to connect to recharge your phone or anything. I would recommend that they should look into a slot or clamp to hold your phone to enjoy while watching the entertainment choices hands-free. Also make it possible to raise the inner seat by the window be able to raise the arm rest up to make more room for larger people to set more comfortably. I would also say other then that stop price gouging the airfare or nickel and diming everything. Not fair for people having to fly for emergencies and be paying for higher prices due to the season or holidays. Your making your money either way and the cost of flying is still going to be the same regardless if there's 100 people or 200 people.

Flight boarded late after announcing on time boarding. Flight arrived only a little late despite late departure. Had trouble connecting to WiFi

The Southwest experience has definitely taken a dive from its early days. You can no longer deferentiate from other airlines. Air travel is too expensive. Southwest is no longer budget friendly. They have lost me as a loyal customer.

Still need to work out the kinks on the new assigned seating boarding process. Otherwise, a very good flight.

Flight attendants very hospitable and friendly. Pilot flew a smooth take off and landing.

Great vacation. Can't wait till next year for another one.

The plane wasn’t full, so we got the best seats

American Airlines is a great dependable airline, on time arrival and departure with polite crew and staff.

Delayed flight due to maintenance and I have had multiple delayed flights due to maintenance in the last month plus

Seat bottom cushions are not good. I’m 165# & they hurt my butt. Plenty of legroom.

The airplane seats were spacious and comfortable, and the flight attendants were friendly and attentive. The food was delicious like never before. The blankets and toiletries were thoughtfully provided. The captain's navigation was steady and reliable. In short, having flown with Starlux, I won't consider any other airline next time.

Like: flights are on time, good boarding process Can improve: planes are old, improve entertainment and make space more comfortable

Mostly good. The WiFi wasn’t working so that was not great.

Things were delayed a little. But that didn’t affect my plans. It was fine. I was surprised it was so full thanksgiving day. The crew were friendly and professional.

Update departure times in a more timely manner. We are not boarding on time if the plane isn’t arriving until after our scheduled departure time.

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.

The flight itself was good. Unfortunately I somehow found myself surrounded by 2 rows of families with small children. I had about all of the seat kicking and yelling that I could take for 3ish hours straight. Kinda wish the staff could have intervened somehow.

Complete and total debacle from start to finish. HUGE mistake picking this airline. NEVER again! Rudest staff in the business.

It's not JetBlues fault but there was a smell on the plane (possibly other travelers) and 3 children behind me that never quit whining. Soccor fans that were very loud. Pilot brought the plane down from high altitude quickly, dropping us hu dress of feet at a time. I've never felt that intense of dropping on other airlines (usually fly Southwest Airlines). But I arrived safely and I'm thankful for that.

Seats were great, the staff was great, and the food was about the best I've had on a plane, and is especially the best of any US-based carrier I've flown. Free Wi-Fi was also great.

The flight was delayed 14 hours and communication was very poor. No one seemed to know what was happening and the gate agent was trying to help people for several flights. She was by herself trying to help 100s of people.

Domestic flights are good. Just stay away from international travel

Flight left 2 hours late with no explanation as to the delay

The aircraft was fine, it’s was just the service. The flight got canceled several times and that was very inconvenient for my 69 years old mom.

Given us a free miles or free flight for waiting for 9 hours I didn’t get home till 5am in the morning and I was supposed to be home at 9:30 touch down.

Jet blue just had great service overall! Only a little turbulence heading out of Austin, otherwise the jet stream helped the speed of the trip!

I had back trouble prior to my flight and everyone was great about helping me.

12 hour delay required getting on and off plane 3 times - would have at least liked to have been offered a snack or drink

They switched our terminal 3 times and we were delayed for four plus hours!!!

The flight never took off and we spent 7 hours at the airport

Gate not determined until I got to the airport - hard to plan the trip to the airport.

Very well recently! Frontier is improving and less harrassing customer on luggages! Positive!

Horrible, first and last time that we use frontier. Kept us in Las Vegas for 8 hours. We boarded original flight at 2 pm right as we were getting ready to leave we were told that plane had issues. Stayed in gate and then after a couple of hours we were told that we were being assigned a new plane and were moved to a different gate. Then after 3 hours they said that the plane had issues and after a while of just being delayed it was cancelled. Thankfully there is southwest that came to rescue. We purchased ticket and left Vegas at 10 pm

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.

Plane was clean but they do not allow bag drop until 1 hour before flight. Just encouraging late fees and other issues. The worst I have experienced. Total hostage situation, pay or you miss your flight.

Typical low fare flight. Very tight seating, no entertainment, no power outlets, no food. You (don’t) get what you (don’t) pay for. The flight boarded and arrived a few minutes early. Can’t complain.

Plane was out if fuel, waited 3 hours for fuel. Then the crew rimed out and flight was puahed to 4 hours later. All we got for this huge inconvenience and a missed day at work was a 15.00 food voucher.
