Plz don't take away free bags and free seating

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

Great flight, 47 passengers on a 180 seat plane. Stewardess was pleasant and cheerful.

Short flight with plenty of open seats. Drinks and snacks were still provided even on such a short flight. <1 hr

A little bumpy ride . No food was being provided due the the turbulence. That was ok it was a short flight to my standards.

Lower number on this flight so spaced out passengers. Able to enjoy more room to relax during flight. It was lovely.

Broken jer bridge. Poor communication about it. Lost 2 of 4 luggage pieces

Coach seating is debilitating, neither my husband or I can walk the following day

Extremely dosappoontined and frustrated. Refused entry to lounge in Detroit despite having Delta AMEX Reserve linked in MyDelta phone app as revommended and also having proof of account. No pillows were available for overnight flight to AMS and breakfast was not served in Delta Comfort.

I liked the screens in the seat headrest with movies to watch. I didn’t like being forced to check my carryon bag and being told there wasn’t room for my bag - when there were 5 bins sitting empty on takeoff. I didn’t like the “I don’t give a fig” attitude of the flight attendants and the delta gate attendants when I asked why they decided to put me out. They gave me a 1800 number to call but I can’t get a live person on the phone. Customer service is non existent. My business must not be that important to them.

The airplanes were so old and out-dated it was terrifying to fly on them.

Like all flights, the seats are small and not comfortable. My first leg was delayed but delta rebooked 2nd leg so my arrival at final destination was only 2 hours later than original flight.

Love delta but the delays and long waits for updates was just too much this time.

Flight was 3 hours late so only had an OK experience

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.

Food and flight attendents with positive dispositions and friendly behavior, more professional attitudes

The gate was too far away for the connecting flight

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.

The flight to Tokyo AA61 took off about two hours late, but then had to turn back. By that time the crew had to be replaced. Then they kept promising to take off in an hour, then in 3, then switch to the next day.

Any sort of gluten free snack option would be nice

They lost my luggage and it didn’t get delivered until the next day.

Would have thought that they would gas up plane before everyone got on board

3 hours late. Not even water offered on a 2.25 hour flight.

I had a carry on and a personal bag. I put my personal item under my seat and on way to the seat I put my bag up. I usually close my eyes and rest as I was on call for last 36 hours. I heard very loud announcements that someone needs to identify their bag. Pretty sure it was not mine until the hostess pointed out my jacket details attached to the bag. I asked why she got my bag out. I got berated and did not want to create a scene. But this person needs to be talked to.

Terrible. The flight was delayed two hours due to weather. Then when we got on the plane, the first pilot ended up timing out and we had to wait for a second pilot. Second pile came on board and we tax it out. Had to return back to the gate because of an unruly passenger. Then the copilot timed out. Had to wait for new copilot. Also had to wait for maintenance to check for fuel. Then found out the second pilot timed out and we had to wait for a third pilot. Was ready to go and then needed maintenance again for another issue. In the end, it was 2 o’clock in the morning when they announced that the flight couldn’t go because the third pilot and the second copilot had timed out.

To start, I’d like to say that every American Airline personnel I interacted with on the ground, especially flight crew, was very friendly and did their best to help me out. Despite this, however, my experience with the airline was an entire mess. The 7:19 PM flight was heavily delayed due to weather, and pushed to 10:30 AM the next morning. Because of this, I had to spend the night inside of the airport. At some point later in the night, I got an email saying that the flight had been canceled. I called the support number, and the representative on the other line told me that the flight was still on and that I didn’t need to rebook. The next morning, no one came to the gate to open the door for the crew until almost 11 AM. By this time the flight crew had been waiting for over an hour, and they had called management to get someone to open the door for them multiple times. Around 11:30, the gate screen had changed to a different flight. I ended up buying a last minute ticket with Southwest airline just to get to Chicago, because the next flight with American wasn’t until 7:19 pm that day. Now, earlier that morning my suitcase had been sent ahead of me to ORD. I went to baggage claim to ask them if I could have my suitcase forwarded to where I was staying. The representative at SDF baggage claim said they could and put the claim in for me. As I was going back through TSA, I got an email that the airline had found my suitcase, but the next step was to send it BACK to SDF. I called the airline support number again, and I made it clear that my suitcase needed to stay in Chicago and to not come back to SDF. The representative told me that they would hold my suitcase at ORD and that it wasn’t going to be forwarded anywhere. Once I got there, I found that they had loaded my suitcase onto a plane to send it back to SDF. Thankfully, I had gotten to the baggage claim counter in time for them to put in a request to bring my suitcase back up. My refund with the airline is processing already, but because of this entire experience and miscommunication at every turn of the way, I will not book with American Airlines in the future.

American Airlines initially postponed the flight. Then they cancelled it an rescheduled us on a flight that would take over 24 hours with multiple stops. They then changed this flight to a reasonable alternative the next day which they later cancelled and replaced with a flight that would take off with an additional 16 hour delay. They blamed weather but I noticed (at 4am) that Delta had direct flights from Charlotte to Detroit. I went on line. Booked it and was in Detroit buy 9am. The interesting thing is they did a similar thing to a family member just 2 days earlier. I don't think I will fly American unless I have to.

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!

Bag should not be so much money. This is how Frontier takes advantage of customers

The plane was comfortable. The time to board was way too slow and very unorganized! The crew was not as friendly as normally. The was not a single time that they offered water nor anything!!!

They switched my flight to Spirit, Never using Kayak again,
