Flight was constantly delayed with significant changes in time, it was supposed to get to Colorado Springs at 8:30 PM but it got there after midnight.

I don't know why flying out of Sarasota requires two plane changes.

Plane was late. Zero service for 2+ hour flight and it was not that bumpy.

Great flight. Good snacks and drinks. Grateful it was free. The flight from Nashville to louisville, i think her name was Tracy (not sure that's right) super awesome, nice and cheerful. She really enjoyed being at work today! She was the person who scanned the boarding pass on flight wn941. She should be recommended for a raise !

I elected to pay for the upgrades and found very little difference

Flight was hours late, unable to sit next to spouse, I have had so much better experiences. Substantially better, only saving grace was that it was a short flight.

I was assigned seat 7E, yet my boarding was Group 5, which caused me to have to put my luggage in the back of the plance above `19 or 20 aisle, as passengers who had boarded earlier took the overhead bins in the front. SW needs to monitor bin space and ensure that bin space above the seat are aligned to those sitting near their seats. Also the seating assignments needs to align with group number. Maybe board those last first and so on? Having said the ALL the passengers on the plane were gracious enough to allow me and other passengers in this dilema to retrieve our luggage and helped us along the way. I always love the flight staff, as always their fantastic and I can't rave about them enough!

The flight crew was extremely rude and especially not helpful when our flight was delayed.

Check-in, Boarding and flight were smooth. All the employees and crew was very nice and funny. They gave the kids crayons and workbooks to keep them occupied which was a big win. I’ve flown Southwest many times and that’s the first time I’ve seen that and it is a great addition.

Still a fan of open seating. Flight was on schedule and arrived on time. The 737 MAX is very comfortable.

The flight was over an hour delayed. The problem was they had the wrong aircraft at the gate, Joe in the world does that happen?

Delays and multiple changes in gates. In accurate info sent to phone. Worst flight in years. With no apologies or recompense.

No AC, no beverage service and no explanation from the captain. 4 flight legs in 2 days with no internet service.

The flight I booked was conveniently timed, had one brief stop and was going to be quick. The flight I ended up getting was delayed, took longer, had a far longer layover and arrived hours later than planned. Thanks for nothing.

Bad experience going to DFW with an IT outage then bad on the way back with a nearly 5 hour delay that’s started as maintenance then caused us to wait further due to weather - which would not have happened if we had left on time.

Horrible experience flying with American. Flight was delayed due to inbound flight delay. Fine, it happens. Then, we were delayed an additional almost 30 minutes due to the paperwork for departure having a "clerical error." Then, upon landing at the destination airport we were stuck on the plane for an HOUR after we landed and pulled up to the gate because apparently there was another plane. An hour waiting for the gate 12:30 AM when the flight has already been delayed due to operational error feels like a complete failure of the ability to do the one thing they need to do apart from actually have the plane takeoff and land. Very disappointing.

It was a 3 hour flight from Dallas to Missoula. The aircraft did not have power plugs, internet or in-flight entertainment. When boarding, one flight attendant was "somewhere in the airport" so delayed the boarding process (not coming from another flight) although we did take off on time and landed early. In flight there was little to no service - we got the standard beverage but no real connection with the crew which feels unusual for a 3 hour flight. A passenger needed help stowing her bag and got no assistance, and actually some passive aggressive comments from the flight attendants about "she needs to remove the extender" and "she'll have to find a place for it". I have seen others be helpful and put a bag in the closet, or support assistance as the boarding door was already closed. Just not a great experience considering the cost of my round trip ticket {$1000}.

Horrible. No AC. No Air inside the plane. We had to deplane twice! It is late almost 5 hrs in total. I almost passed out and about to call 911. I asked the crew to be honest and open the door. The lady next to me was lay down in the floor due to heat and no air inside the plane. I got headaches, can’t wait the replacement flight about midnight Dallas time. I end it up rebook for next day flight and stay overnight using my own pocket in a hotel nearby due to headaches and can’t breath. I still have a headache this morning. Still not decided yes how to file this issue to AA and/or FAA.

Worst communication. Delayed boarding for two hours without a single announcement until hour 1 had passed - on time status showing until our flight was supposed to takeoff and the crew had already walked away. No one was boarding. Disgusting part of DFW overcrowded with no AC on a 97 degree day. Then the first app update is that we’d take off in 15 mins… but again no one had boarded a full flight. No announcement in the terminal so everyone is just crowded around a disgusting place with no info for over an hour which turned into two. This was an overfill flight and a disgrace to passenger decency all while likely just trying to fix their own issue of overbooking. The worst airline at the worst airport.

The flight was delayed almost three hours. I understand delays happen from time to time, but this flight was delayed no less than 10 times. I wish the amount of time of the delay was more accurate, versus delaying in 10 or 20 minute increments many, many times.
