No wifi, seems to be very common with Southwest currently. Everything else was normal.

Flight was delayed by 2 hours, meaning that a flight to Dwnver which should have arrived at 11pm came into the airport at 1 am. Made for a very long day.

Great job! My family doesnt fly often but we felt safe 100%

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.

First time I've had to use the disabled accommodations. And I could not have had a better experience with Southwest, i was having trouble getting from one terminal to another due to my heart failure. And the next thing I know a Southwest agent had made sure. I had a wheelchair at all my flights. Can't thank them enough.

The new seat assignment thing is wierd. If you don’t pay for a seat they always assign you a middle seat regardless of how many people are on the flight. Idk… the new company that bought Southwest is trying to make it more profitable, but I’m just not seeing it. The flight attendants aren’t having as much fun anymore. It just feels like the airline is slowly dying. IMO. We shall see if Southwest is the next Toy’s R Us.

Great vacation. Can't wait till next year for another one.

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.

It was good. I wish you had gluten free snacks for my husband.

No tv. No free wifi. They need to ipgrade these planes - especially on a 2 hour flight.

delta wifi wouldn’t work boarding was not in sequence flight crew spent most of their time on the phone with the lights off pretending no one wanted or needed anything

Flight was 2 hr. delay, making me miss my connection to my final flight home to Roanoke. Now 12:38am in the morning and I just got the first available ticket at 5:30 pm tomorrow evening. Sleeping in the airport.

I am a die hard Delta flyer, but they missed it on this flight. It was on their very dated 717-200 aircraft, which I knew when I booked it so I knew it wouldn’t have seatback screens. However, the internet was awful and it wouldn’t even send texts a lot of the time, much less even connect to the delta app. It was also very hot while in the air, which never happens. What was even more disappointing is that the crew only gave me cheezits and a beverage, even though I was in Delta Comfort. The main cabin fare gets these items. I didn’t get any kind of improved snacks and that was unacceptable. The crew wasn’t very visible at all either. If this was my first delta flight, it would be my last. I am just going to assume it was a one-off flight.

flight was delayed 4+ hours. there was really no understanding of why? weather? the last hour of delay was post boarding. pilot seat was broken. was that the real reason? nonetheless, long day of inconveniences.

Flight got canceled 4 times, missed my connecting flight due to delays, have to wait to go home tomorrow

We departed and landed early which was a nice surprise. The boarding process was slow.

Arlene was a great flight attendant. I also liked how one of the other flight attendants gave us a heads up about snacks and asked everyone to remove their headphones when it was their turn to order. Good idea.

The WiFi was not working. That made for a long flight.

Extremely disappointed with Delta. They canceled flight last minute and then I rebooked the other flights and with which were delayed as well

Awful. Delayed flights, missed connection to Toronto. Hotel vouchers were for already booked hotels x3. Giant waste of my time

The entertainment is a bit limited, it would be better if they added some games to play besides the movies and tv shows. But the seats are comfortable and the crew is polite

The pilot had to extend the flight time from san antonio to Houston to burn off fuel. This caused a lot of unnecessary stress since we had a tight connection to Aruba. And with no other flights going to Aruba we were worried about spending a night in Houston. We had to to run to our connection because of the flight crews mistake. Not happy.

Fine. The issues I had were associated with luggage being delayed from Turkey to Tanzania

Do not like the size of the overhead bin. I think staff should monitor the size of suitcases that are being carried on by passengers to ensure they meet the size requirement.

Flight was good and crew was super polite. However, there were around 5 kids screaming the WHOLE 2 hours. I understand kids have to come but parents need to do something to control their children. They make the experience terrible, especially after finishing 16 hour shifts at the hospital I needed some sleep, which I did not get.

Gate agent did not hold flight for connection, provided no assistance to get new flight

Nothing they cancelled my connection and couldn't get me on a flight for 3 more days

The plane was dirty and the in seat air wasn't blowing as planes usually do.

The customer service was excellent! Check-in, baggage check-in, boarding, the flight went very smooth.

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.

Deplaning time. Having to wait 10 to 25 minutes after boarding to leave the gate. Having to wait 10 minutes to park at the gate to deplane.☹️

When you pay for Premium Economy on an 787 and you’re promised amenities for the extra money, you expect them to work. They didn’t. USB connector wouldn’t charge continuously. 120v outlet wouldn’t hold anything you plugged into it. The adapter would just fall out. The noise canceling headphones stopped noise cancelling in the first 15 minutes for EVERYONE. No one on the plane knew how to fix it so I couldn’t listen to any movies. I just put in my AirPods and went to sleep. Very unhappy with the crappy Panasonic entertainment system. I won’t buy premium again.

Flight delayed 3 times due to maintenance (on exact same plane that had just brought us from Boston to Miami). Eventually changed to a different plane and gate.

Both flights were delayed. One by an hour and the other by 1 1/2 hours after boarding.

My first time flying American Airlines, my first flight to CLT was wonderful and flight attendants was nice and had great customer service. My second flight from CLT to NY was very delayed due to whatever reason the crew was not greeting other than that I’m rate 8 .
