The flight itself was good. We were delayed 1 1/2 hours which was not good.

10.0 ExcellentCindy, Mar 2024TPA - MDW
Read more about Southwest reviews

The flight itself was good. We were delayed 1 1/2 hours which was not good.

Flight was fine but new boarding policy was a drag Xtra time passenger group And Waiting until entire bridge empties before calling a list preferred... Waste of time

Wish that they would space out the boarding a little. COVID is still around and is real. No entertainment. Miss the peanuts.

The crew at the gate in Baltimore were rude and intimidating and insensitive to the needs of traveling families. They treated us like nuisance children ruining their day rather than the reasons they were working, paying customers with children who were anxious about the boarding experience. I would only travel Southwest again if it were the only option, especially if traveling with my children.

With COVID still around, I wish they wouldn't bunch us up so much at the boarding gates.

Cramped older 737. Noisy passengers nearby. Wish you would change and make KC a hub with a direct from OKC. Best new airport!

Pleasant and responsive flight attendants. Adequate drinks menu Good sized, comfortable seats

I never like the fact that if I don't check in exactly 24 hours before the flight time, I get to board C, and that means sitting between 2 individuals. I would like assigned seating in the airplanes.

A bit bumpy, but otherwise uneventful, and made up some delay in flight

Boarding and deboarding painfully slow. Southwest is typically delayed in my experience.

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

The flight was delayed instead of leaving at 11 it left at 12.20

United WiFi is consistently unusable (it can take 10 mins to load a single web page). If you need Wifi to do work, be prepared to lose half a day of productivity.

Good movies, iffy pay WiFi, food ok- on time though and that was great!

Awful…flight was delayed more than 12hrs, missed all connections to Fort Wayne, IN, had to get flight to another city 2 hours from my destination, flight was again delayed by 40 mins because they did not have enough fuel, again missed a connection, finally arrived in Indiana at 11pm…but before my 2 hour drive home, ay, no Five That Our Luggage Never Made On The plane and Still In Chicago

Boarding was friendly and quick. While the plane model was older with no live tv, the entertainment was full of movies and tv shows. All food was available. Pilots were very communicative with status of the flight. Flight landed on time.

The Palm Springs to Chicago O’Hare was on Time and Palm Springs airport is easier navigate. As our connection was only an approximately 50 minutes, we asked staff for insights for the Chicago airport in terms of transferring into the other terminal from which our flight left, and they were unhelpful. However, the United App was very helpful in terms of notifications and even providing directions. The Chicago to Detroit flight was significantly delayed which we all know does happen. However, there were very few updates or notifications as to why this was happening when we would actually arrive. It took nearly 30 minutes for bags to make it to baggage claim. We arrived nearly 1 hour late on a 40 minute flight.

Flight cancelled due to fog. No other flights available for 36 hours. Directed by United to book passage on another carrier, and submit receipts for reimbursement. Did that. United now states they will not reimburse. Currently out 2 grand.

The flight was delayed by 4 hours !!!!! It was very uncomfortable , and they told us only one our before departure

The flights from Ottawa to Albuquerque went smoothly enough though on on flight they didn't have how water for coffee or tea and on another there there was no ice. The return flights from Albuquerque were delayed by mechanical problems on both flights. Ottawa was a ground crew maintenance issue.

Flight was fine. It took an unusually long time to have baggage delivered to the carousel in ORD.

Average - flew with Jet Blue internal and it was far more comfortable and better food and entertainment. Notable difference

The flight got canceled due to mechanical issues, and he to be rebooked and missed my appointments for that day

The flight was scheduled to depart DCA at 12:30 pm but was delayed twice on the ground so that we were finally scheduled to depart at around 4:00 pm. Once we boarded, it was announced that takeoff would be delayed again to fix a hydraulic problem which delayed our eventual takeoff until around 5:00 pm. Once we departed, it was a smooth flight back to ORD. We did not get any explanation about what caused the original significant delay. In my experience, this happens frequently with AA.

The only problem experienced was a ground stop in Chicago due to weather. But the crew handled everything professionally. They prioritized rebooking those passengers who had connecting flights and then deplaning the other passengers. When the hold was lifted, they efficiently re-boarded all the passengers so that we could depart before our departure limit expired.

Our second leg to Jackson WY was unable to land due to weather. We were flown back to Dallas after stopping in SLC. We were given hotel rooms and vouchers. We were told that we would be back on the same plane in the morning. Instead we were given a different flight with different seats. Not a good experience. No one knew what was going on.

Turn on the heat. Flight was way too cold from Arizona to Chicago.

Perfect flight. On time departure and early arrival. Smooth flight.

Overall pleasant was delayed and caused transportation issue when landing

The arriving flight was a few minutes late, but the gate crew helped to deplane and board our outgoing flight quickly and efficiently. We were able to depart quickly and arrive at ORD almost at the posted time. Great job.

The seat are terrible. Don’t even think of sleeping on a Spirit flight. The kids that run the plane aka flight attendants are pretty rude and straight forward. They get the job done but without class.

I had a death in my family and booked my flight on Spirit. My flight was cancelled the morning of my flight, no explanation, no help to rebook, nobody to talk to. The next available flight was 2days later !!!! Terrible airline, will NEVER fly with them again!

They took a horrible route with a lot of turbulence and I eneded up getting sick. Even if the flight takes longer. Don't put people life at risk just to get to the airport on time.

Every thing was fine ,low price,easy on time ,clean, good staff, really no issues

Had to board plan 2x due to lack of security check after 1st boarding

Miserable. The crew was rude, the flight was delayed 5 hours for mechanical reasons and then “weather” even though other planes were leaving.

They kept Changing the flight times. It was delayed several times and at one point it was supposed to depart at 3.40am! At which point we ended up staying overnight and booked long a separate United flight for early morning departure. The spirit flight then got moved up and left at 1.30 in the morning when it was supposed to leave at 9.40pm the night before.

Flight was delayed...not horribly late. Just before push back engine shut down for a quick replacement item that took about five minutes. After that, everything was smooth and the pilot was able to make up time in the air so that our arrival time was not too far off the original anticipated arrival time.

Only inflight purchases for food and water. Nothing comes with ticket price. Have to purchase bags, food...

The flight was delayed almost two hours on the front end, and an hour on the backend once we landed and waited for a gate to open up. We were told to remain in our seats during that whole delay and I had to go to the bathroom badly. I was unable to hold it and was forced to urinate in my pants while in my seat. I then had to sit in it until we finally deboarded and I was able to change my clothes.

Not have to pay for every single item to take a flight. Seating and delays sucked.

Flight was cancelled and I had to spend the night in the airport lugging my suitcase around

If you don’t check in 24 hours in advance, they will charge you $110 to check your bag instead of the $30. I did not get an email with this information and did not check in. In addition, my flight home was cancelled at layover and I had to spend the night in the airport, and then have another layover at another airport before making it home. Will not fly frontier again.

Terrible. Seats are bad and the baggage policy is inconsistent

Flight delayed 3 times, resulting in late arrival, rental car place gave car away resulting in increased BS charges because I was late. Frontier blows.

I paid for extra leg room. The flimsy plastic seat underneath the floatation seat did not line up with the arm rests. It seemed as if the plastic part was zip tied on but immovable. This caused severe uncomfortable for the duration of the flight.

Left Denver late, then sat on tarmac 30 min after arrival

Better than I expected but I did pay for a seat and carry on bags ahead of time.

Crew members are very rude and not cooperate with passengers.

30 minute delay due to boarding and settling of a family.
