Our flight to Philadelphia was full and the gate announced that there would probably be a full state for carry-on luggage at Zone 5 of boarding. In reality, they announced that the overhead bins were full after Zone 4 had boarded. Passengers need to be prepared.

Flying Alaska Airlines from Boston to Seattle was an example of getting exactly what you expect. A no-frills basic experience, but one where the important things were accomplished, timely departure, on-time arrival, no drama, no glitches, completely as anticipated. I paid a little extra for one offered perk (seat selection), and I'm glad I did because my early morning flight was full. Next time, I'll likely pre-order a snack, since they looked good, were served promptly, and are priced right.

The agent at check in and at the gate were less than thrilled to be at work. I'm not a fan of Kayak's placement on the plane. I got put in the middle seat and none of my preferences were used.

The agent at check in and at the gate were less than thrilled to be at work. I'm not a fan of Kayak's placement on the plane. I got put in the middle seat and none of my preferences were used.

In ATL they have two sets of departure screens. Follow what is on your airline's departure board - the ATL Airport Authority departure board had completely incorrect details about the gate assignment for my flight, which would have made me miss boarding.

Flight was delayed it was hot while sitting on the plane, one engine was working on the plane until they had to do some jimmy rigging down the runway in order for the other engine to charge up. It was ridiculous

The flight was very good and the staff was very friendly and helpful!

The only thing I would say is we tried to get on a standby earlier flight, but with our fair we couldn’t. That seems senseless to leave with open seats..

Very easy to use and convenient, you can perform any action within the same portal

In a world of delays, Delta was on time both ways! Boarding was fast and efficient. Staff was friendly. AND wifi worked.

WiFi didn’t work. Flight delayed 3 hours Crew members were illiterate Seat lean back did not work.

Flight was delayed, we could have been notified earlier and in a consistent manner. App was not refreshing for another passenger to get the latest flight status. We could have stayed and waited at the hotel instead of waiting at the airport had we known the flight was going to delayed for more than 5 hours. The toilet is too tight, and needs to be cleaned more frequently (every hour). The entertainment screen froze, the touch screen not responding to touch. We were upgraded to comfort, it is more comfortable than regular economy seats.

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.

Booked through Kayak Business, had a seat in middle and towards back due to booking rate, not comfortable.

Was great in general, try to respect time and excuses when slight changes have been made, appreciated!

A long delay. Don't travel late in the day.

Super friendly with lots of drink options an entertainment. Friendly crew.

Standard flight with a drinks and a snack- overall very quick flight. The flight attendants were very strict, bordered on rude.

Outstanding service, efficient & friendly crew, flight was safe, comfortable & on time

Delayed - weather wasn't bad at either end. Also sat on tarmac in ORD.

They told us yesterday APR21st that they were cleaning the plane and we got delayed. After that they said they didn't had any crew for the flight so they cancelled the flight till next day.

The crew was great. Very friendly and responsive. The plane was old, small and tight. We ran out of overhead space and I had to check. Middle seat was particularly tight.

The flight crew on this leg of my trip was very friendly and pleasant. Every one of them was humorous, as well as helpful and accommodating. This group was BY FAR the best crew I’ve flown with. They deserve kudos.

Boarding was fast, easy, and we landed early. The entertainment system was very buggy and kept resetting throughout the flight.

Not having an assigned seat until boarding and then having to check my bag.

Flight emergency landed in Chicago due to “Odor” in back of plane . Had to buy ANOTHER TICKET to get to Boston cash out of my own pocket . Then they would notchange my return flight time without a 400. Charge!!!! Insulting.

I purchased ticket so our daughter ( a minor) can sit next to her mother. No help at gate after kayak insisted that this could be done. She ended sitting by herself

Flight was as expected. But it was delayed an hour. Also, my luggage got damaged. So that sucked especially since the damage made navigating the airport difficult. Walking to get ground transportation is sooo far away now and my checked bag was difficult to carry.

we were an hour delayed after boarding and given no reason. Headsets cost money. Also there were openrows with no one setting in them but we were told we were not allowed to swtich.

Crew was very friendly. Did not like being jammed in the back middle seat. Don’t understand why I can not select an aisle for free based on first come first serve. Also first time I’ve been on a flight which attempted land then circled Detroit airport multiple times.

Terrible. There was a lot of misleading information regarding ticketing, seat upgrades, & boarding group. I also expect my seat will recline. I have back problems & it is very painful for me of the seat doesn’t recline. In addition, when I choose a fare that allows me a carry-on bag, I expect to be able to carry it on. Not be forced to check it. Thos happened on my flight to MCO & back to Boston. Not sure I will ever fly JetBlue again. Further I bought the ticket through hat deal. I will NEVER do that again. They were incapable of providing an accurate record locator # for either leg of the trip. I had to call them before each flight with me VERY stressed about whether I would actually be able to get on my flight. Who does that? Who books flight & then FAILS to give an accurate record locator? Twice!

The flight was delayed 4 hours and the JetBlue people at the counter kept lying to us and telling us it was due to weather however all other flights were going in and out of NY and FL. Then they lied that the plane had to stop to refuel. Then they lied and said the plane needed a tire change. JetBlue is the worst. Then they gave a lot of people meal vouchers however I didn’t know they did that and they didn’t offer anything to me.

My experience with Jet Blue was wonderful. My experience with Kayak sucked and will never use again.

Boarding gate at LAX was too crowded—two gates next to one another

The flight was delayed about an hour for a maintenance specialist to approve the maintenance repair

This flight was delayed but it worked in my favor because my Atlanta to Dallas flight was delayed.

This was a hard flight. 3 delays out of OKC (1 on the Tarmac). Delay in Atlanta coming to Dallas. total travel time was the equivalent of driving from OKC to Atlanta.

Like: flights are on time, good boarding process Can improve: planes are old, improve entertainment and make space more comfortable

Had to wait for a gate for a long time, then waited on the run way for a long time before leaving. The actual flights part was good.

The airplane was an old model, the overhead didn’t have enough room for people’s items and made boarding and boarding disappointing and stressful. Crew allowed passengers to bring more than the permitted baggage sizes.

Flying in the United States with the major airlines has become so underwhelming. A 2-3hr flight in most other parts of the world with the major carriers of the area comes with newer, CLEANER aircraft and significantly better in flight service in terms of both staff attitude and a actual meal service.

On time departure and early arrival. Flight attendant very nice.

As we approached Denver, we encountered quite a bit of turbulence. I know this can sometimes be the case as I frequently fly this route but not on American. My gripe: Usually a pilot or co-pilot alerts passengers to the possibility of turbulance ahead of time. This did not occur nor did he communiucate during what was a pretty rough ride.

The AC broke and we were onboard for 2 hrs waiting for them to fix it. It was so hot and we could not get any water or anything to drink. They finally let us off the plane after the second attempt and we boarded a new plane. We didn't land till 12:15am!

The boarding process was simple but the seats were very uncomfortable. The staff lady was also very hard to understand when she spoke over the intercom about procedures and updates. Other staff members seemed like they were just tired and didnt want to be on the plane. Im used to happy attendants and being able to understand what is said over the speakers.

There was no flight. Call the airline and confirmed. I have no idea why you think that I flew on the days that you say I did.

They canceled my flight and never told me. There was no follow up email. I had to buy another ticket the day of.

Easy to get our TSA pre check #added. Flight crew was great and entertaining and we landed early!

Flight was delayed 6plus hours Did not take flight Customer service was terrible Will never fly again and will spread how terrible you are You stink

I didnt have a flight. Kayak must be on drugs because I confirmed with spirit that I had no booked flight.

We were surprised to be charged $99 for a personal item. And of course everything offered on the flight was an additional charge. Other than that the pilot flew and landed the plane well and the attendants and fellow passengers were nice enough.

baggage drop off was a bit much. I felt like I worked for spirit airlines since I did all the work.

Gate changed multiple times. The staff seemed annoyed that we asked for water. We had to pay for the water as well.
