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

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.

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.

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

Flight was a little late taking off. Seats are too upright, no ports to charge devices, no wifi, no entertainment
