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

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.

1.5 hour delay, poor service, no compassion from the crew. Terrible experience

Multiple delays and not straight answer from the United team

Stewardess spilled orange juice on my clothes/seat no help no apology just threw napkins at me to clean the mess up. Not Happy.

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

Electric plugs didn't work. Entertainment system wasn't working

The design of the light switch on the arm rest is ridiculous.

Smooth boarding process. Early departure, smooth flight, early arrival. The entertainment package has very good recent movie options. The flight crew were friendly and professional.

leg space better than expected. two washrooms for one plane isn't enough.

The gate attendant let me walk right by her with a bag too big for the overhead compartment

I just got back from a trip with 3 flights each way. The flights were good and we were happy with out experience. There was one steward on our first flight that was harsh and grump with passengers. It did not leave a good impression. All of the other flight crews were great on the other five 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.

Great flight. Departed early, arrived early. However they were out of meals for sale. Also, we arrived early and the gate was not available so we sat on the taxiway for quite a while (not JetBlue’s fault).

It was too hot in the cabin. The AC did not help.

Love the mosaic program, being able to move to an extra space seat for free is awesome

Smooth boarding and friendly crew. Unfortunately as soon as we boarded the unit that provides air circulation failed. The pilot informed us and requested maintenance technicians to check it out. The plane became uncomfortably warm without any fresh air coming in. Plus the repair delayed our departure. I am glad the maintenance crew were able to fix the problem. I also was without use of my tv monitor for the first 1/3rd of the trip.

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.

I paid for the service of having the right to choose my seat and it was not like that, they put me where they wanted and I explained to one of the staff that they were before boarding and they were very rude. I am traveling with the family and they put us in separate seats.

Everything was great except for some reason crew and ground crew could not figure out how to deal with an electric wheelchair and it delayed us 20-30mins. Was pretty frustrating for passengers and the captain.

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.

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.

Good crew and a great experience. Only good things to say.

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

I had a horrible experience from the time I dropped off my bags until the time I landed. The staff taking the bags at the check-in counter prior to security, forced me to check my baby stroller, even though it weighed less than 20 pounds. their excuse was that the wheels were too big. I have never had an issue gate checking this exact same stroller in the past either on American or on any other airline. when I asked for the agent to show me the rule about the size of the wheels on strollers, they told me to look it up on the AA website. I did so, and did not find any indication that wheel size was a problem for gate checking strollers. The only limitation would be the weight of the stroller which mine was below. I was left with a one-year-old child and all of my carry-on luggage, diaper bag, and the like to walk around the airport without the assistance of a stroller and had the same issue when I exited the plane and had to go all the way to baggage claim without a stroller. In addition, while on the airplane, I was told I can only get one bag of cookies as a snack, even though I was with a child. Apparently my child and I were supposed to share a cookie. While this latter issue is a minor one, it is just another example of the absolutely horrible customer service that American Airlines provides. In addition, the 737 aircraft that I was on was extremely hot and the air vents above the seat were so far away from the aisle and middle seats that it was comical. I could barely reach the air vent to adjust it. I had to ask the person in the window seat to do it for me. The whole experience was just a nightmare.

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

Landing in terminal 2, but my luggage is terminal 3. We (and others) were looking for it in terminal 1. We probably missed the crew broadcast, but the communication could have been clearer for non native (or elderly) passengers.

I chose the seats when booked the flight and paid for them. However after checking in I found we were assigned different seats!
