R
2.0 Poor
staff and crew were great but the flight delays for the last few flights are insane. After a long day of work and you will get a notification of flights delay is not the message we want to see. And for some reason it keeps happening often this year.

I love southwest. I can not wait until all the planes convert to the upgraded planes. I love the charging option and the newer seats. Thank you from a very loyal Southwest customer.

My return flight was much better than the flight there! I paid for seat to Veagas but not the return. Thankgoodness they assigned me a seat with additional leg room as I have back and leg problems. I really appreciate it. With the flight already being super expensive due to gas prices and having to pay for bags (now) I needed to save some money.

4.0 Mediocre
My first flight from LGA to STL was not good. They didn't do service until over halfway through the flight, the internet didn't really work, and the crew all seemed like they didn't want to be there.

6.0 Okay
We were stressed about landing as our connecting flight was about to start boarding, being unfamiliar with the airport or where the gates were. We exited the plane to discover we were at the gate we needed. We would be getting back on the same plane but nobody told us we could have just stayed onboard. My wife and I were seated on aisle seats across from each other. We asked if there was a way we could sit together. Once we were at cruising altitude they let us move to an unoccupied row so that was nice.

6.0 Okay
It’s Southwest. The seats are small, the snacks are meh, it’s $50 to check a bag. It’s exactly fine. Could have been better. Could have been worse. It’s not Spirit
