It is southwest seat was ok. Not the most comfortable seat

I’ve always loved Southwest. No issues at all. I was flying standby and the gate agent was extremely friendly and helpful. Boarding was smooth and I was able to get a window seat in the emergency exit row. Crew was fantastic! They were very professional and accommodating. We had to divert from our destination due to weather but the flight crew kept everyone at ease and informed us of all pertinent information. Excellent flight

The price of the tickets isn't matching the flight experience. No matter how long the flight is, you're only getting pretzels. The flight attendants looked unkept and over it.

Plz don't take away free bags and free seating

The seats were a bit cramped and worn, but otherwise okay.

I would have liked to arrive on time - not 5 hours late!

After a 3 hour layover in Denver my flight was delayed over 5 hours! No explanation; no assistance; no offer to provide compensation; no one at Southwest was willing to offer any assistance. 8 hours in the Denver airport - ridiculous!

It was a perfect flight in all aspects! Both legs!

Only one drink pass through the cabin for a 4 hour flight. Quite rough and bumpy landing.

Boarding process, crew were good. But the seats were so uncomfortable that was all I could focus on. I literally had to sit forward so that all 3 of us could fit in row. I will try to avoid Southwest in the future for any flights over 60 minutes.

Our bag was lost so that made unnecessary chaos On our trip

After a 5 hour delay waiting at the gate (3 delays adding up) with no clear reason provided, we finally boarded flew 3/4 of the way to Toronto then were turned back to New York. As we neared New York, the pilot declared that it was his fault, something to do with timing and him not being allowed into the country???? How could the airline let his happen? They had hours to prepare and make sure they had a crew available for the flight! We ended up in Toronto a day late with no sleep.

Terrible and im avoiding them in the future. My initial flight was delayed causing me to rebook my flight and when speaking with the representative to rebook I explained this is the second time my flights were delayed and they did nothing to help me. I wasn't booked to comfort plus or given a voucher or anything. I was almost late for my meeting that I needed to attend on Monday because of the games delta played delaying my flights even more and putting me in the very back of the plane next to an extremely intoxicated passenger

Although the flight left late, we arrived early. It was one of the quickest boarding and off boarding experiences I’ve had. It was kind of annoying the only drinks they had were water, coffee, and tea. The flight was very smooth, temperature was just right, and flight attendants were friendly.

Seats were really tight and the seat belts did not give enough slack.

The dear was very limited in space. I could put my water bottle in seat basket. Also, there was no inflight entertainment in the delta app?

We were forced to wait nearly 50 additional minutes before leaving the terminal.

Customer service at the gate in the flight was exceptional. On time. Aircraft and seat was decent. Thanks Delta. 💗

Crew was nice. Flight was timely. Seats could be better as well as the food considering it’s first class.

The WiFi has been awful on my last few Delta Air Lines flights.

Excellent. Although they used to greet me as a mosaic member and provide a free drink, early boarding helps me to keep coming back to JetBlue.

No music app working: no economy meal on five hour flight; hour on tarmac at the end waiting for a gate. Flight itself was smooth and easy.

Communication with the customer and stay is important. Staff off with a minor inconvenience but it worked out of course. Also this was a very old Mint Class plane. They snuck this one in on us. The updated aircraft are much better.

The flight itself was fine, but the boarding process was extremely frustrating. There is no one scanning boarding passes - passengers just scan themselves and enter the jetway. By the time my husband and I got on the plane and were halfway to our seats they determined there were too many bags on the plane and everything at that point needed to be checked. This created a lot of unnecessary chaos. They should have alerted people before getting on the plane that they would need to start checking bags instead of waiting until people were already on the plane.

The best flight I’ve had in a while. The plane was like 25% capacity, if that. Smoothest boarding and deplaning process I’ve ever experienced. Wish all flights were this smooth.

In flight on demand didn't work at our seats. Only a single beverage/snack run.

Traveling with JetBlue from NYC was convenient as accessing JFK airport was straightforward via the LIRR to the AirTrain. Maneuvering through the terminal was hassle-free, which was a pleasant start to the journey. However, the flight experience itself left much to be desired. The seating arrangement was notably uncomfortable; despite securing a window seat, space felt cramped. This was exacerbated by the middle seat passenger encroaching on my area, which made the flight less enjoyable. Additionally, while the in-flight entertainment system initially seemed like a reprieve, the sound outlet on my seat was inoperable. This issue turned what could have been a manageable three-hour flight into a rather tedious ordeal, as I was unable to use the entertainment system effectively. While JetBlue provided a smooth process in terms of airport logistics, the on-board experience highlighted areas in need of improvement, particularly in terms of comfort and entertainment system maintenance.

Over 2 hour delay for a 50-minute flight is unacceptable, especially in normal weather. Very poor communication via app

In-flight staff was very helpful and excellent. However, the flight was delayed by 90 minutes. Also the boarding process should be expedited in case of delayed flights. This will help the passengers trying to make international connections.

Kayak sent over to jet blue my account being Mike Callaghan instead of Michael. I have a jet blue account with Michael that was connected

There were five broken seats on the plane. The crew was very rude in telling people they had to get off the plane and get a flight the next day. No call for volunteers, but telling people they had to get off. One woman was flying with her elderly mother and daughter and was told she had to leave or all three had to leave. Fortunately, a volunteer offered to stay. The situation was handled poorly.

Delays on all NY flights. There was no communication on why but they didn’t say it was weather. Other carriers were not delayed.

Extraordinary service in business class, and very good breakfast and snacks. A really lovely flight.

They cancelled our flight without warning OR a refund. Never doing business with American Airlines again! This is the second AA booked trip in a row that we've had challenges with.

I got bumped due to weight restrictions even tho there were empty seats on my flight. I got put on an other flight with a stopover. My flight that originally was going to take 5-6 hours ever up being 14+ hours and my luggage arrived to my destination without me because I was made to check in my luggage on my original flight when I was deemed ok to board only to be asked to deplane. Worst flight experience.

Flight cancelled. Added a day and a half to my travel. American Airlines DID put me in a hotel for two nights, but have not given any money back for any of this! I spent money on an apartment at my destination that I basically wasted because I could not arrive.

I was pleasantly surprised with an upgrade at boarding. I finally had a mostly gluten free food options and a very attentive attendant.

It was good. It’s been a long time since my wife and I fly any where and things have changed. Our trip was to see our new grandson. We fly economy and that was not good for my bad back. It was a quick flight but uncomfortable.

Staff at the gate were incredibly rude, hostile and threatening. Never fly American Airlines.

AA had a nationwide tech glitch today and after two connections snd hours of delay, I arrived 7 hours late to my destination

The reps working at the airport counter were dumber than a second coat of paint.

My costume jewelry was stolen out of my bag. Got to airport and my bag weighed 45 pounds- 5 pounds over cost me $100 Long lines in tier one. No entertainment No WiFi no free drinks or snacks

Not very good. Paid in excess of $400 for assigned seating for my family and that was not provided. I want that money back.

The seats were hard molded plastic covered in plastic vinyl. And the scam to charge people extra to sit together. Don’t they know we can just ask someone to trade seats. And watching the staff separate young children from parents… super classy. We had to guilt them into offering up our seats. This companies policies suck. Don’t give them your money.

The seats were awful, hard plastic covered in sheet vinyl. The airline tries to scam you into paying extra to get seat together when the flight wasn’t full. They were going to separate a family with young children but my wife who had a row to herself gave up her seat so the young mom could be with her young boys. I’m never giving this airline my money again.

It was a short flight so no food or entertainment….

Seats are uncomfortable but price is good. Guess I can put up with misery for four hours.

I’ve never traveled on Frontier before. If you want basic, no frills, friendly service at great prices then give them a fly!

Cancelled and declined to find alternatives Earlier flight is 2 days later Sent the cancellation notification very late, wish I knew earlier would have stayed to watch the Miami open final game Very disappointing service

The worst flight of my life. Never will I fly frontier again
