Southwest boards more efficiently than the rest in my opinion. Boarding should start at the opposite end of the plane from the door and preferably window to door but instead it's front to back and takes forever when each passenger stows a bag and blocks the rest. I have seen the back to front work well in other countries.

Here’s the part that confused me the most. JetBlue flies only from terminal 5. Delta (at least) arrives in terminal 4. Be aware that there is a lot of walking to get out of terminal 4, then you board the sky train, then you walk more, and finally get to terminal 5. There, surprise! You have to go through security again. At JFK, some security lines are ridiculously long and slow. It’s very annoying that transit passengers must go through that again when moving between terminals. One more thing related to terminal 5 where JetBlue flies - there is absolutely nowhere to sit and almost nothing to eat before going through security. The security lines were better organized though and it didn’t take that long.

Chicago airport is super chaotic. We had come in from an overseas flight and were required to get our checked bags at Baggage Claim and recheck them for our next flight, which took a while. Then after going through a LONG customs line (again) and rechecking my bag, I was told to take a shuttle to a different terminal for my final flight. Even though I never left the building and had no access to the outside world, I had to go through security AGAIN (boots off, dump out my water, wait in long lines…) My advice is to be sure you have at least a couple of hours between flights to deal with the insanity.

Make sure the flight you select has more than 3 hours as time allotted for transiting to another flight. Most of United Airlines flights get delayed and if you don’t have enough time, you’ll be missing the next flight for sure. Have extra budget for shelter expenses because most of the economy tickets does not qualify for shelter accommodation/ voucher when your flight is delayed.

Overall good, just screaming kids in the area the whole flight.

My experience will Southwest was good. I wish there was more entertainment and the boarding process was slow at time but other than that my experience was great definitely will be flying with SouthWest again.

Flight was delayed by 2 hours, meaning that a flight to Dwnver which should have arrived at 11pm came into the airport at 1 am. Made for a very long day.

I think Southwest is the number one airline that anyone can fly I have flown for the first time Frontier and what a joke and their customer service United was a very strange experience I'm only sticking to Southwest from here on out for sure

Great job! My family doesnt fly often but we felt safe 100%

Great job Southwest! My family doesn't fly often but we felt safe the whole time.

SW can't get their wifi right. I upgrade to insure wifi service but the last two trips had intermittent service. Not worth the extra costs.

The flight was late. The crew was rude. There was no food. Cramped and uncomfortable. Nothing about this flight was good.

Crew was rude, flight was late, wifi didn't work, no food, basically nothing about this flight was good.

It was just okay, no frills, basic transportation with no luxury. No screens on the seats, no water or drinks on a short flight. Full flight but at least it was on time.

We never made it on this flight because we missed our connection due to o delayed flight from Jackson.

We had a terrible experience. The flight was delayed several hours, so we missed our connection. We were told to wait at the airport. At around 11:00 pm, the flight was cancelled. There were no available seats out of Jackson for the next two days. Fortunately, we had the foresight to rebook on United for the next day. However, we had to spend a long day at the airport and an overnight at a mediocre hotel. It was a miserable way to spend part of our vacation. We also sacrificed our $450 deposit on our California hotel because we could not get there.

delta wifi wouldn’t work boarding was not in sequence flight crew spent most of their time on the phone with the lights off pretending no one wanted or needed anything

Everything worked smoothly, never had a concern with the flight from start to finish.

Friendly flight attendant Quick checking for baggage drop Quick TSA lines

Crew was absolutely fantastic and we’re so welcoming and friendly ❤️

We got stuck on the tarmac taxiing after landing early so we didn’t get off the plane until an hour later than we thought we would

It was okay. We were delayed for weather reasons, but the pilots and the flight control staff figured a way around the storm and were able to get us to Los Angeles safely. Not all the staff members were polite, but the entertainment on the flight was good.

So terrible. My flight was 4 hours delayed and we weren't notified til last second within an hour of boarding. WE had to sit on the plane for 4 hours. ridiculous.

Missed the Flight from Atlanta to Roanoke due to initial flight from Houston being 2hr. late. Now waiting 17hrs. till my first available flight.

It was a short, comfortable flight. It did leave an hour late due to the pilot having to be replaced (family emergency) but that didn’t inconvenience myself & my friend. The situation was explained, eventually.

Flight was delayed “due to earlier delays of that plane”, so we were nearly three hours late.

There was a piece of plastic baked into my buttermilk biscuit! I have a pictures. The flight attendants in first class were really apologetic, and tried to rectify the situation. I I am very appreciative that they were able to give me some packets of pretzels and gummy bears. I understand they don't personally handle the food until warming it up so I know it wasn't their fault. I don't know whether it was a newer aircraft, or different food packaging, but I was happy that when the food was being warmed up - it didn't smell like plastic. Jokes on me with finding plastic in my food.

We were forced to eat vegetarian food because non veg food ran out. The breakfast was mediocre.

The seats were very uncomfortable. I paid for the front economy. i swear they added a row of seats in there. It was so tight, that I could measure the distance between my seat and the one in front from my elbow to the tips of my fingers plus six inches. The seat cushion was completely worn out. The dinner was very good. Thank you for having a vegetarian option as a standard. But breakfast was nothing but sugar. that's not food. The crew was crabby and rude, especially in regards to coming to the back gallery. And the entertainment choice: why would you put violent movies on the choice? the Godfather? Some movies with black women being beaten over the head with clubs? What the heck? You know that when there is a movie on a plane, everyone gets to watch it. Why choose the most violent titles possible? The total number of movies were very limited, and the television, even more so. No games were available on the set. The wellness section was nice, thank you. I appreciated a galley in the middle where I could stand. The seats were unbearable.

The seats were uncomfortable, as if the cushions haven't been switched out in many years. I felt like I was on an old bus. The food was delicious. thank you. Onboard entertainment, very limited. Unless you like violent movies. Why in the world would you have such severely violent movies on a plane? if you don't want to see such things, you don't have a choice. Have you considered that when choosing entertainment? Good god. Why would you have the Godfather? Or black women being brutally beaten with a club? Why in the hell would you put that kind of material on a plane? As for Kayak: Why when I ordered Qantas, was the plane on United?

The head rest is too big and cannot be placed differently/removed. Causes one head to tilt forward and increase back pain

We sat on the hot plane for ours with very conflicting messages. Some (most?) of this may be due to the flight control staff, but we were also repeatedly getting "we are leaving"/"we are not" messages. It was very uncomfortable

It was terribly delayed with zero support from united airlines. I reached at 1 am in the night. They did not provide any option to change the flights.

It was great. All the crew were professional and nice.

Terrible check in experience in Miami airport by a so-called supervisor. Food came and they were picking up trash within 5 mins. Did not get fed again for about 6 hours. No chance to buy anything on board, horrible experience. Flight attendants have no control over passengers dropping off bags closer to the exit, not close to their seat.

I will never but. through kayak again. and American Airlines. I will never fly again on. They're both thieves.

It’s love good long way travel!! I always want more give me price down i want ever month travel I miss travel only North Carolina to Thailand in my love her !!

The departure and arrival was on time. The fact that I could load my boarding tickets on the American airlines app.

My flight was 4 hours delayed on departure at 6a causing me to miss my connection at DCA. I had to scramble to find a seat home on a later flight and instead of an exit seat, I was in row 30 on a flight getting me home 5 hours later than planned. The AA team on the ground did a fine job. AA continues to run the airline like the passengers are cargo.

Over the course of 7 months of travel, I can count on my hand the number of times the flight has departed on time. Majority of the instances have been related to non-weather reasons. Would not recommend flying this Airline

Efficiency of supporting mechanical teams who changed a wheel on airplane in minutes. So no delay, and pilot made up the lost minutes in flight. Comfortable seat.

Comfort in premium economy is worth it for long hauls especially on the 787-9P Dreamliner with the modern updates. The food was okay. All 4 of us selected the same meal, 2 of us had very dry hard to cut chicken, the other 2 were tender and good. The sides/salad/dessert all very good as far as airline food goes. Crew were very attentive. Will be hard to ever go back to regular economy!

Flight attendants and crew were great! This plane was fine. It was clean and everything worked properly. Now, the gate change was not communicated. No text or information. It wasn't far with the gate change but it still changed without any communication. Not sure if this is on American or Kayakl. Also, internet was the worst. I would never have ATT. 3+hr flight and weak internet. I think I watched the commercials to get on at least 6 times. Terrible internet!

Flight was delayed, boarded, sat at the gate for more than 30 minutes, left the gate then waited on the pad for another 30 to 60 minutes then returned to the gate, deboarded and was cancelled... alternative flight was not booked automatically. Waited in line for 30 minutes but fortunately an alternate flight to a different destination was found ... no thanks to the travel agent used by kayak

The flight was great . But you only had one vegan item on the whole flight and someone prior to me took it . I was so disappointed cause I came in from the flooded area and couldn’t pick up anything prior to my flight .

I really didn't like anything. Paid for my checked luggage online ($79) and then was told that I would have to paid another $79 for my carry on. Was not allowed to enter the terminal until 3 hours before my flight and when I finally was allowed to check my bag and enter, my flight was delayed 3 times. When I finally landed, we were all instructed to "run off the plane" as they had to do a quick turn around to Las Vegas. Me and several of my flying companions will never fly Frontier again.

I paid for the upgraded bundle. Was worth it! Great experience round trip!

It was awful everything about it terrible I will never ever ever ride it again

It was awful ....my first time flying on it and I will NEVER fly it again ....everything about it was terrible .....most especially the flight attendants

Crew was kind of grumpy and there was no beverage service at all. Sodas were $4. Disappointing.

There weren't enough employees at check in took awhile to get bags checked. There wasn't a wheel chair for me, I was sent to someone who turns out to work for a different airline, if My flight hadn't been delayed I probably would have missed my flight as it was, by the time I arrived at my gate, they started boarding in about 15 minutes. I don't know who took me to my gate, definitely was not the normal people who take passengers to the gate. I'm guessing she may have been in a management position. I wish I knew her name, she went beyond to help me. With that said everyone was kind, and were doing the best they could. So, I choose to say it was an Adventure, stressful start, but good. In the end went well. The situation was not only difficult for passengers but the employee's.

The staff at the check in counter was so rude. Made you feel Incompetent

Frontier scheduled a 40 minute connection in DEN. What they failed to mention was that they “close the doors” 20 mins prior to departure, which means you only have 20 mins. Not enough time. Possibly against DOT regulations. Filing complaint.

Flight was scheduled at 9:40pm. Got delayed to 10 am, the next day. crazy
