I have roller bag with food and medication told me I couldn't bring on my 2nd flight today. 15 years flying with SW never an issue with that bag.

I have not flown Southwest in awhile and had a very pleasant experience. From ticketing to boarding to the flight. The flight left on time and landed ahead of schedule. It won't be so long next time!!

Everything went smoothly and we even arrived a little bit early.

Boarded on time but once we were ready for take off, the crew determined that, although every seat was taken, somehow someone was on the wrong flight. Delay, delay delay, announcements and ended up with one person checking EVERY ID against their passenger Manifest only to figure out it was a "clerical error." We departed 54 minutes late causing me to run in the St. Louis Airport to make my connection and lose the priority boarding spot I had paid for. Unnecessary delay.

Southwest's seats are the least comfortable I have ever sat in.

For my birthday trip this was my second time ever flying, this trip was the best.

Crew was great flight was great baggage claim was a failure. It took over 1 hour for bags to arrive. Poor communication poor effort when I spoke to the supervisor about the delay

Everything was great except the food. The pretzels are really crappy.

I had a front row middle. I am not a big person and I barely fit in between that seat! No place to put my arms, even though the guys on each side were not taking over the arm rests. It felt like a frontier flight (if that tells you everything )

Appreciate that when flight was delayed, our next connection waited for us.

Enjoyed it very much. Especially liked the free WiFi that Delta offers.

The boarding process needs to be refined. Sometimes the gate crew calls out the zones and then flip to showing the.zones boarding on the gate monitor display. So, unless you are huddled around the gate lanes watching the monitor, you could miss your boarding zone. Suggest the zones be announced each time a new zone is allowed to board.

On time flight. Seat comfort could be better in the Comfort section.

Perfect flight both ways. On time, courteous staff, plane comfortable and cool. Best domestic flights I’ve had in awhile.

This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

The important things including boarding and the flight being on time and safe were excellent. The disappointment comes from the comfort and amenities. Was misled by the "availability" of inflight internet- there is an extra cost. The tray table was broken, the bathroom door stuck and flight attendants were competent but not very friendly.

Flight was delayed, missed connectingnflight to DC. Put me on flight to Baltimore, had to rent a car for $200. Plane was old, wall peeling around window. Flight was packed, every seat full on small plane. I spent 14 hrs on Friday in airports and missed my planned weekend event.

You could have not cancelled the flight (AA, which I will be flying from now on) left for BOS despite the fictitious weather issues (that no one in my Boston family could see). You could have rebooked my direct flight to another direct flight instead of sending me though JFK, the worst US airport after O’Hara You could have rebooked me on a Main Cabin seat (like the one I paid for in my original ticket instead of putting me a the last row on JFK->BOS leg, pocketing the difference in ticket price But I do not really care whether you will ever do that in a future because in a future neither I nor anyone from my company (unless they pay out of pocket) nor an of my clients and partners (if they heed my advice) will ever be caught dead on any of Delta flights

Temperature in the plane was quite warm for the entire flight - actually just outright hot making for an unoleay4 hours. Crew either couldn’t or wouldn’t do anything about it. No acknowledgement or apology. All passengers were commenting on how hot it was.

As we lined up to board they gave our plane to a flight going to Newark. So then we got delayed until they could find another plane. Flight crew was ok. I’m assuming since it’s a shorter flight they only offered water and coffee.

We called Kayak for a change due to the TSA situation in Atlanta. What we got was a canceled return flight (in error) and we had to find the mistake. Not happy with Kayak who blamed it on AA.

Small plane, poor meal choices for first class, bad terminal and boarding experience at LAX

Boarding delayed 20 minutes for no reason, no wifi, in flight entertainment, or snacks / waters?

This flight captain and crew were amazing, started ahead of time of departure and reached 30 mins before arrival time. Amazing!

Improvements in communication and empathy are absolutely necessary for American Airlines staff (top down). It’s like they are numb to the needs of their customers.

I like the speed of boarding and deplaning and the fact that everything was on time. The crew (attendants) were probably quite new and did not begin the in cabin service until 30 min before landing even though there was little to no air turbulence for the last 1.5 hours of the flight. It made for a mad scramble at the end to get trash collected and carts stowed before touch down.

The flights was delayed by hours and it was the firmest landing I have experienced in my life. My back is still sore.

I did like the employee's, they are very friendly and all smiled most of the time, Overall, from checking in bags to getting on plane, not enough employees to be able to get all on the plane, therefore I was not able to get on the plane, due to no one wea there for me to check in my bag, so I decided to go thru the security point and by the time they were done with my bags, I was told that my bag cannot be checked in, and then found out that the lady that does the check in was boarding the customers onto the plane, she said that she was going back and fourth, there for was not able to get on the plane, which changed all my flights by the time I got to Dallas, I was on standby 3 times, and wasn't sure about being able to get on the fourth plane, so ended up buying another plane ticket, so I could make my destination on time.

Not sure about entertainment as I didn't use any, so maybe there should be an NA option on this survey. Otherwise everything was just as it should be. Of course I wish planes were more comfortable and had seats that would tilt back further.

American Airlines “Randy” questioned why I needed preboarding and denied my request for same. Then Randy attempted to berate me when I boarded with my group. I was seated in an exit roll with a young man with a disability that exhibited difficulty controlling and settling himself. But Tandy questioned my disability. The flight was horrible. It was overpacked.
