Kayak could’ve posted the correct gate number. Almost missed my flight.

I wish they had movie screens in the headrests. The seats are much improved, more legroom and recently renovated. Bathroom was clean. Staff was outstanding!!

My original flight was extremely delayed but I was able to join the standby list for an earlier flight. I was grateful for this feature but I wish I could’ve gotten my standby confirmation sooner.

Glad flight made it out. So many delays due to hurricane. everyone did a great job.

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

The trip was good. Short, uneventful, and can't ask for more than that My one complaint is that I had signed up for wheel chair assist between gates. I fractured my foot/ankle in two places and needed the help. Neither flight did the requested help appear. I ended up walking through both Atlanta and Nashville Airport and was a very unhappy traveler. While I know that it's the airport responsibility for the service, I wish that SW had at least verified that the assistance was there as requested.

I liked that we arrived safely. I did not like how Southwest personnel blamed the boarding delays on wheel chair passengers. If there is a national wheelchair basketball tournament occurring, be ready as a company to respond with appropriate resources to match your cudtomers needs.

I love Southwest! I try not to fly with anyone else!

Lost cabin pressure and had go back to the originating airport. We were left sitting on the plane for more than 30 minutes with no directions from Southwest on what was going on, other than the app telling us there would be a flight at 12:30 AM. I finally got off and went directly to a SW desk and rebooked for the next day. I understand that malfunctions happen, but SW was totally unprepared to manage the situation and did not serve the passengers. To make matters worse, they took one hour to find my checked bag.

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

Flight team was great and we even arrived ahead of plan!

The boarding agent guy in Lexington on 7/23 that boarded the flights to Atlanta is very rude for working in customer service. I know there were delays but he was dismissive rude and arrogant. Most native Kentucky residents are nice and very cordial he needs to eat a big ole piece of humble pie. I watched him be rude to several people and as much as he could of filled up a delayed flight to save you money and he was so rude to people it was ridiculous. Next no water or snacks on short flights is awful 1st you delay a flight then do not even offer water on the flight.. No thanks I like delta better but I travel ever week and to be treated like this might as well fly American at least they offer water and have better rewards.

Boarding was quick and i made my connection early due to early arrival time

No food or drink, Not much conversation with crew. They didn't come through to check on people. There were no charging stations or wifi to watch movies. It was like being on a bus in the air.

Our flight was delayed by over 4 hours due to a maintenance issue. They announced a new plane was on the way. We were given a $12 food voucher ( airport food is quite expensive You can’t even by a water and a small snack for 12:00. 4 hours later we boarded and landed in Atlanta at 10:20 ish pm. Of course we missed our connection and we were given a hotel voucher and another food voucher ! We didn’t make it home until 11:00 the next day ! Unacceptable

From checking to boarding, it was a seamless experience. The service agents were so helpful. The flight crew was so pleasant.

Delta has too many delays now days. It is 1:06 am now. I was supposed to land in Norfolk at 10:30 pm. I got re-booked through Detroit and I’m still in Detroit. I hope to be landed in Norfolk by 3am. I’ve been in airports for 12 hours as of right now. There is a weather delay now but most delays lately have been maintenance.

This is the first time I've been disappointed with Delta. I was called by Delta to see if I would volunteer to change flights since my original flight home was overbooked. I accepted. The modified booking only provided me a 35 minute layover - when you subtract the fact that boarding closes for a flight 15 minutes early, that gave me 20 minutes to run for one end of the airport to the other. I barely made it. On the 2.5 hour flight to Tampa, the crew repeatedly let us know over the intercom that they cannot serve drinks or snacks due to safety/turbulence. I would have accepted this reason if they did not CONTINUALLY SERVE DRINKS AND COOKED FOOD to First class. If safety is the excuse then the entire plane should be strapped in for safety. On top of this the air conditioning vents were not working correctly and the plane was uncomfortably warm. I love Delta and am a loyal Delta traveler, and I have never had an experience like this. I don't know if there's a disconnect between availability among third-party sites like KAYAK and the airlines or what, but when overbooking causes issues like this for travelers it should be reviewed and changes to the booking process should be made. I blame BOTH KAYAK and Delta for this terrible experience.

I always fly with Delta. My friends tell me their horror stories of flying with other airlines. I just smile and say, “You should fly Delta”

The plane smelled like a sewer. Multiple passengers complained. It’s a safety and quality issue to clean these planes.

My luggage was not sent with us. Not sure if this is Envoy Air responsibility but that was a very BAD experience

American delayed the flight for a crew rest period. The delay occurred late in the evening - the earliest i can find is 10:20 pm. With a 6 am flight anyone on the flight would have already have been asleep (unless you are insane, a vampire or on drugs) and at least for me i was already on the way to the airport at 445 am the next morning when i discovered they delayed the flight until 9 am. Given the incoming flight was in the air at 6 pm the evening before this should have been figured out a lot more timely that was there only crew to use. Just frustrating given there is no consideration for customer experience anymore in flying.

Flight was extremely hot and they made us check our bags when the space was nowhere near full

The only thing to like was that we eventually got to our destination

Finding the gate was very confusing. Our boarding pass listed one gate and the staff verbally told us a different gate.

Our 8:45 am flight kept getting delayed. Boarded after a 2 hour delay only to be taken off the plane again. At 12:30 pm, we are told there was a new plane and we had to change terminals. Flight was delayed again to 1:50 pm. Eventually boarded again only to be on the plane for over an hour. Flight finally took off at 3:30 pm. 7 hours after original scheduled time. To top it off, couldn’t even get coffee on the plane due to turbulence.

16 Hours delayed, NOT because of the cybersecurity Microsoft issue, but because we were one flight attendant short, then when the missing flight attendant showed up two hours later, the flying shift of our pilot had expired, so, now no pilot. American Airlines is the new Spirit Airlines, actually, that is not fair for Spirit, they are probably better.

My previous flight was late and did not connect properly. The gate was closed and I missed this flight.

The agents at the gate were rude. The stwards were pleasant. The seats were comfortable. The tray table had crumbs on it. A passenger talked constantlt and very loudly for the entire flight annoying many passengers. The stewards did not ask her to speak in a lower voice but my travel partner did.

Had to rush between flights due to first leg being late, then pulled for additional security screening and attendants were in no hurry, took other people at same time as my husband and I further delaying us and causing additional stress.

Frontier feels like a family I Worked for Eastern Airlines back in the day and I felt the family vibe that I had then. Thank you

Flight was delayed but it was very smooth. Crew was very nice. Seats are uncomfortable but ok.

They didn’t offer a water, even after I asked

It didn’t happen. I booked it and then was told it wasn’t available and then forced to pay far higher prices for a worse option

The third party booking with cheapflightsfares was awful. Kayak should NOT partner with them. They sold me a bundle including seat selection and carry-on, but did not book the carry-ons with Frontier, so I’m out of pocket for $414 more while I await resolution.

I loved the staff on the plane. So friendly and helpful! However, there was an argument and misunderstanding by the staff and a customer at the gate, and the staff member was being unprofessional. When we arrived in Atlanta, we waited 1.5 hrs for our luggage to arrive. When I asked the airport attendant, they said Frontier had the longest wait for luggage out of any airlines, and that they could not be held responsible for the delay.

Delayed. Text notifications were slow. Not much information o what was happening. Boarding was slow and confusing. Wasn’t even offered water other flight. Had to ask. No entertainment at all. Felt like.a Greyhound bus.

There was no one at the counter to assist with our check in. The app didn’t work, so I arrived at the airport with time to check in and I couldn’t because no employees were there. When I finally got someone on the phone, it was inside the 60min rule and they said I could no longer check in and they could sell me another ticket. We had to scramble and pay an additional $800 for tickets and THEN AFTER (about 60 min from my original convo with customer service and 10min after original departure time) I had boarded my new flight, there was email saying my original flight from Frontier was delayed and leaving 2hr 50min later, but I STILL wouldn’t have been able to check in. Which means customer service should have been able to see it and let me check in because I was well within my check in time. When I call Frontier, they hang up on me. So their app didn’t work and they employees left and they take zero responsibility or assistance with their “customer service”

Boarding was on time and plane departed as scheduled. There are obviously no amenities (food, drink, entertainment) on Frontier, but there also didn't seem to be any issues with luggage space either.

sluggish boarding and arrival procedures, fake nice flight attendants, and lots of delays.
