I understand the delays caused by the storm, but that doesn’t mean the systems had to be chaotic. The app showed one thing, the screens showed something else, and the gates kept changing every 10 minutes. It was a nightmare trying to figure out where to go.

I understand the delays caused by the storm, but that doesn’t mean the systems had to be chaotic. The app showed one thing, the screens showed something else, and the gates kept changing every 10 minutes. It was a nightmare trying to figure out where to go.

One, we were met with more than six hours of delays with no information flowing from the airline to the passenger. I had to continually refresh for updates to departure time - which changed multiple times throughout the day. Updates were never pushed to me nor was an explanation provided for the delay until this morning. Two, while they claim that "due to the short flight" no beverage service would be provided. Our flight was mostly empty. I'd think given the massive inconvenience, SW could have shared a Diet Coke and some peanuts. And BTW, SW used to always make these available on this flight back in the day. Let's be honest, this is cost savings at the customer's expense.

Unfortunately, I left my headphone's case in the bag of the front seat. I was seating on 9C. Hopefully the found it and I can get it back. I have not been able to get in contact with Southwest. Other than that, everything went fine.

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.

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.

Just having a little bit more legroom would've been nice.

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.

Had to find alternative flights because of AA lateness and bad planning

When we landed, there was only one gate agent to handle three planes, including retrieval of carry on luggage. I was stuck in the jet way waiting on my carry on for almost 20-30 minutes. NOT GOOD

AA changes gates constantly at DFW. I got 5 or 6 gate changes. Fortunately the last few were all in the same terminal. I know DFW so it is not a big deal for me but it is a bit disturbing.

Uncomfortable, not managing boarding process and managing people in the way waiting to board at a later time. Terrible delays

Nothing went well. The crew timed out, they sent us to 7 different gates, my original flight got delayed 8.5 hours, and the best American could do was give us a $12 food credit.

Delayed 4 hours which is out of control the airlines BUT what IS in control is their service. After 4 hours delay, they charged me for a beverage on the flight - completely unacceptable. Then I woke up a $12 beverage coupon AFTER I get home - that I can't use. This was HORRIBLE customer experience. I fly weekly and have a choice and will not choose American again if not credited for this flight and/or awarded miles. This was a poor experience.

We sat on the tarmac for an hour. After our flight got delayed 30 minutes because the crew was late.

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.

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 .

With a business flight, having a designated seat in the aircraft, I was denied boarding at the gate at last minute without any genuine explanation. The staff used profane language when asked for reasons. Viva overbooked and passenger had to pay for it. The food voucher that was provided did not even cover the the full meal and water for a single person. It should not be running in service.

One of the flight was delayed an hour. We then boarded a new flight. We were told to unboard after some other time. To wait for the next flight for another hour. I paid for a short flight that turned in to half a day of travel.

No entertainment, charging, nor wifi on board but I napped for basically the entire time so it was alright. Was allowed to switch seats because the flight was not full but everyone was assigned to the back. Comfortable seats and we got moved to the emergency exit so the extra room was nice.

They closed the gate over 25 minutes before departure and I didn’t get to board.

The smart/express line to check in was a mess, employees not doing the process smooth and quick, using their mobile phones, talking to their coworkers

THE AIRLINE FUCKEN SUCKS... NO DAMN PROFESIONALS.. NO CURTESY THEY CANCEL THE DAMN FLIGHT AS ITS ABOUT TO TAKE OFF

They need to have enough immigration forms for every one. They should offer free water to everyone, unless some one needs bottled water

Viva continues to strive for the worst airline experience ever.

They cancel the fly and don’t give a money refund.

The air conditioner was poor and we were delayed 1 hour for no apparent reasons and no information provided
