Delayed and once landed waited very long for the luggage

Nice managed … it was a smaller plane, so the seating wasn’t as comfortable.

The Southwest airline was ok. A big thank you to Kayak team (David), who worked with me on Sunday afternoon to rebook my travel from Burbank, CA, to CVG. My original flight on Sunday was delayed, so I had to cancel Sunday flight and rebook my travel to Monday. Could not have done it without help from David from Kayak team. Ante Soda GE Aerospace

Seated at front bulkhead for a smidge extra leg room away from home and on flight back home. Away crew was very proactive about assuring our carryons had space close behind us (because no seat in front of us our personal items had to be in a small bin overhead). They actively required passengers place overhead luggage on its side so more items could fit in bins. Home crew made no such efforts. I had to struggle back rows to get overhead bags upon landing, no crew help then either, and some disgruntled passengers as I and others retrieved our bags. There was a system that worked pretty well. The home bound crew just didn't feel like working.

Southwest has inacted unfriendly customer policies like other airlines. Watch the fine print very carefully if you are having to alter flight arrangements. Rules are now complicated and very stilted to travelers sacrificing travel funds (unlike before where the simple, straight forward flight change policy was worth the extra premium for ticket price.) On the positive side, SW Flight crews are still wonderfully helpful.

Flight left on time and was early landing. Seats not comfortable and not enough space…

Very good. Exactly what I expected. We did have a slight delay.

I think Southwest can offer a whole can of beverage instead of such a small cup

it was great. the crew is exceptional. the flight was on time.

I like the boarding procedure. Handle the bird strike issue well.

The wait in the tunnel to enter the plane was too long. The counter personnel, specially ''Israel'' was really not welcoming considering Delta Standards. Other than this everything was good overall.

an he late. super rude gate agent, to every person. spoke down at people.

Delta staff was exceptionally helpful and considerate. However, the first two of three flight legs were delayed making connections tentative and stressful.

This wasn't my experience with Delta. It was just the Pegasus flight. Seats were very hard. Staff was kinda rough. Not very nice. Charged me for snacks. For a 4 hour flight I would've expected more.

I had a flight cancel and had it rerouted. When the rerouted they put me at a window seat instead of an isle. It was hard sitting by the window because the couple with masks on were making out. I get motion sickness which is why I need to have the isle seat.

They ended up paying for the bag twice, but the counter wouldn't take my baggage receipt. Left it to me to resolve. Not sure how to resolve the issue.

The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.

I just can’t understand why are you sell to many tickets ???? We had to wait 2 hours before 13 people from our flight take money and go to next day flight!

The only real hiccups in the flight were things beyond Delta’s control - turbulence which delayed food service and a departure delay caused by some VIP plane which stopped all departures and landings for 30 minutes - and was never explained to us by the crew. Otherwise good flight. I would fly Delta again.

The plane was frigid, and leaked water from the ceiling all over me and my seat.

Did not like the check in guy quibbling over a couple pounds at the luggage weigh in

Boarding was 2 hours late and then we were delayed another 5 hours on the tarmac. I'm sure the crew were also tired, but some of them were rather snappy. The special dinner I ordered was not served, and they only served a tapas box on takeoff and breakfast before landing. That was disappointing in premium economy. However United was good at rebooking my connecting flight.

It was pretty good, they give a small blanket, neck pillow and earphones. The only bad thing was not big enough leg room for your bag and feet. They gave us a snack, dinner, and breakfast on flight and food was good considering it was on a plane

Even through the flight was delayed due to storms near IAH The flight was great! The crew was so hospitable and professional

United Airlines is my preferred airlines and I am thankful for Gary who also help support me on the phone to switch my flight literally last min.

The flight was on time. I generally don’t drink or eat on short flights and the seats were good and the flight attendants were friendly. That’s all I expect

The attendant were friendly. I suggest you have a medical attendant on board every flight so that in case someone is sick , he/she will help them.

My flight was completely full. Making me very stressful with people walking around all the time. I believe airlines can do better for entertain people during the flight.

The flight and boarding were easy peasy. I was traveling with my 4-year-old, so a smooth boarding experience was especially appreciated. My only piece of feedback is really about where our gate was in O'Hare. They've shoved four gates into a tiny corner of the B terminal and there isn't early enough room or seating for everyone. Not United's problem, but did dent the overall experience.

The United website was easy to use and had all the information I needed. I needed to change my flight and it was accomplished easily on line. I was also easily able to upgrade and for a reasonable price. Boarding went smoothly and the flight was in time. The service was good in board but the crew did not seem happy at all. Limited availability of meals - not much choice for purchase and in business class they ran out of one of the meal choices by row 4. .

I paid extra for a seat up front and at last minute was moved to the 2nd to last row - which I could have had for free. No reason and no refund. Really great customer service American

The first flight was delayed by an hour and a half, so we missed the second flight. They rebooked us on the later flight and I have to sit in the middle for more than 5 hours. Terrible experience. No more American Airlines.

Flight was fine, but not having WiFi was a major negative

I was trying to take 2 one and a half hour one way trips and I experienced almost 20 delays over the course of those two trips. Only a few of them were due to weather the rest was disorganization

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

The flights were terribly delayed and then cancelled which forced us booking another night at the hotel. Very poor management from American Airlines

American switched my flight to a 5 hour layover then cancelled my whole reservation with no notice and refused refund. Won’t fly with them again.

We sat on runway for an 1 hour because they were short handed at key west airport was not fun

The WiFi and app don’t work as easily as other airlines

Late. Then next flight was an hour late due to mx.

Very good flight that left on time and arrived earlier than anticipated, which was a plus! The crew members were very welcoming and helpful. However, the temperature on the flight was very cold - almost to the point of extreme discomfort. Additionally, requiring passengers to pay $8 for headphones to access the JetBlue entertainment was disappointing. Those earbud jacks are not used with most technology and would not be able to be used. There was no option to use Bluetooth for my own earbuds. Beyond those inconveniences, the flight was good.

Flight was delayed many times. The crew was friendly but you eleven had to buy headphones to access the movies in the plane. $8 is not a lot for one person but it is when you travel with all your family.

JetBlue is always consistent and great, the food is limited in selection, but at least you can grab as much as you want on snacks and drinks at the Blue Locker.

Very well organized both boarding and deplaning. Very satisfied with the service I received.

Flight was on time arrived at the destination 10min early they kept in touch via email

at the time for boarding the lady just call Group A and no other goups and everybody from A to F go inside without the right turn,and when we get in theres no more spsce for carry on , the ones that get in at not correct group from the back occupy our space !!!!! a mess !!!!

The boarding and flight were ok, but there were several painful issues. The flight was 3:20 in the air and almost four hours door to door, but they only had snack packs on the plane. They really need to have food on longer flights or make it clear to everyone that they won’t have food. They also advertise free WiFi, but it did not work for 90% of this flight. Again, almost four hours door to door. If I had known I was flying spirit for JetBlue prices then I would have planned differently.

I think the food / snack service was very poor. tehy could have done better. Evrything else was great

No wifi, not even while close to the continental US or Puerto Rico, no entertainment whatsoever (TVs not working). Totally disappointing.

Wifi screens were great. Both flights were delayed, spending all day flying home and then getting home at 3am ruins the next day also.
