The first leg of the trip was great. The second leg from BWI to RIC was late, which was more screenful and tiring that late in the evening.

The first leg of the trip was great. The second leg from BWI to RIC was late, which was more screenful and tiring that late in the evening.

Excellent. The lady boarding the flight was awesome. Very efficient, and she got everyone on line.

I love no assigned seats and bags fly free. If Private Equity gets their way and forces Southwest to change they will be everyone else and I will stop being loyal to them. DON'T CHANGE YOUR BUSINESS MODEL!!!

The crew was nice. Boarding sucked. Instead of loading from the back to the front people just sat wherever and you had to wait for them to move to get to a seat. And the flight was 25 minutes delayed.

The crew was nice. Boarding sucked. Instead of loading from the back to the front people just sat wherever and you had to wait for them to move to get to a seat. And the flight was 30 minutes delayed.

I boarded last because of my boarding assignment and was given a middle seat at the back of the plane. I’m 6”1” so it was really tight. I wish I just had a seat assignment instead of a general boarding group. My bag was way at the front and my seat at the back. Was never offered a beverage and had no room to move.

No space for our carryon and needed to check at plane before boarding !

The crew was dutiful but seemed detached and bored. The boarding process is ineffective. No reason I shouldn’t be able to sit with my wife. I checked in at the first available minute and still got boarding tow “C”. Southwest used to be my first choice due to value. But no longer. Southwest is like traveling in a cattle car. Suggestion: be the first to make Wi-Fi free!

Chairs are not reclinable. Not ear phones for sale. Seats should be assigned to avoid confrontations. Flight attendants were AMAZING.

The flight attendant was proactive in helping with placing carry on in overhead bins. This was the first time I had ever been offered help without asking or obviously struggling. Many on the flight were older people like myself and vertically challenged. I would hope this would be the norm on all flights.

The seats on the aircraft are like sitting in a rock. During the boarding process they recognize Active Duty Military, why don’t they recognize Retired Military. I’ve always preferred Delta, this flight confirmed why I still prefer Delta.

when you can say you don't remember being at any point upset during a flight, the airline is winning .

The staff was very friendly. The seats seemed quite small. Overall the flight was pleasant.

It was literally one of the worst travel experiences ever. My flight got delayed by over an hour and there was no communication of this from the gate staff. I realized it by checking the screen periodically. Once on board the flight attendants continued to serve alcohol to a man who was clearly already drunk and that was making a bunch of commotion. Never again will I fly United!

Charging and entertainment didn't work. The meal was horrible. They only came by with the drink cart one time for the 8 hour flight. They did come by with water a couple times.

Exceptional, I’d like to specifically recognize Robert for his outstanding customer service. He is professional, pleasant, and personable.

Some sort of compensation for missing work because of a cancelled flight that was United’s fault

At least the delays were short. Business class, even in the new planes is very crowded now with crappy tray tables

The new Airbus A231neo has neat tech but the economy seats are so tight together that I always had my shoulders against one passenger or the other. I was very miffed that Basic Economy REQUIRES check-in of bags other than your personal carry-on; if you want to offer low-cost airline prices and then add services for a fee, just let me carry on my duffel. Hell, I could have put my carry on IN the duffel and called it a day but the gate agent would not let me; I ended up paying $40 for the risk of losing my bag. Not the worst flight, but far from the best.

It is a modern tragedy that any airline expects you to travel for 14 hours in such discomfort and that the only way to add comfort is exorbitant prices. I was in pain by the time we landed. Shameful.

This flight was fine but had no time to breathe as the connection was late from Sea to ORD.. Super stressful. If we checked bags, the trip would have been very distressed.

Seats were very uncomfortable. I paid extra for a seat with more leg room, the seat was no different than a seat at the back of the plane. Flight attendant was rude.

the food choice of packaged chips and popcorn was utterly ridiculous for first class

Check in agent was helpful and nice. Flight was OK. Our flight in Chicago was delayed 8 hours without an explination. This was our journey home. After a horrible flight experience on on the way to our vacation where our plane was diverted for an emergency medical issue, was grounded for hours, we missed our connecting flight by 25 minutes, and it took a day yo get re-booked, this was yet another bad experience that American seemed unwilling to help out with, much less compensate us for the

Late and next flight even later. Who leaves at 245 am and arrives at 330 am ? No wifi, 4 hr flight and one bag of pretzels? AA should be ashamed

No problems on this flight. Entertainment system worked well. On time take off and arrival. Smooth most of the way.

Fantastic! If it had not been for a check-in agent in Knoxville I may have not gotten my passes on British Airways. I couldn’t check-in online because British Airways had messed us the info on my tickets to London & Inverness. AA’s was great! British Airways was a continuous series of delays and frustrations.

Extreme weather delays. Missed my flight to France and I ended up leaving the plane.

We received a flight delay notification over 24 hours before the flight, but it seems American didn't do anything in that timeframe to get the flight back on schedule. Gate agents were still determining when our plane would arrive. Didn't have catering ready to go when our plane did arrive. Flight attendant timeout before we left. There was a flight attendant on board who could work the flight (trained on that aricraft type and was within hours), however American chose to wait for a backup to arrive, which delay the flight further.

It was freezing in there. When I asked about it, the response is “we would have to tell them” and then she just walked away and continued to serve beverages. Everyone was cold and they didn’t care at all.

Got on quickly and easily. When it turned out the other two seats in my row would be occupied, a nearby flight attendant immediately let me know that I could move one row behind me since it was an empty row, I moved into the window seat where I could relax enough to take a little nap. Can’t ask for much more.

We had a 40 mins delay, but the pilot was good about keeping up informed. No food/snacks or drinks when u in the air-they have to be purchased. They charge for every single thing .

I’m not a fan of Spirit Airlines from a not-so-good experience the last time & I swore I would not fly this airline again- bc they charge for EVERYTHING. I only flew Spirit this time bc it wasn’t my choice. I decided to use a “Mystery Ticket” bc of the great price, not knowing it would choose this airline! I found out on this trip how they pick a random seat with a “sticker” for a prize-are we in first grade? just doesn’t seem right & now the first 3 or 4 rows get special treatment-we all paid for our tickets, not just them.

particularly nothing to like plane just turned to be a hmm flying bus, yet in buses from another country at least drink and snack are free ... and seat could be just a bit more ..adjustable? ok ok i know i am asking for too much but ..dreaming is not forbidden yet

Fantastic !!! Seamless boarding. Meticulously clean. We left and arrived early.

The flight was delayed, and we waited for more than an hour on the plane.

You get what you pay for, but those tickets weren't cheap, so I expected better, but Spirit is just one of those airlines.

Cancelled the return flight moments before boarding, horrible customer service in assisting with any rebooking. Never again will I fly Spirit.

Flight got diwngraded last minute and left us stranded. I was told I’ll be given credit for my luggage and seat upgrades but haven’t got anything yet

Crew was nice, explained emergency protocol very well. Flight took off and arrived on time. Pilot explained the small delay that occurred with docking and providing updates. I would definitely fly spirit again.

The seats were dirty with crumbs and trash , looked it had not been cleaned up from a previous flight

Nothing about the flight was good. The crew was rude and unwilling to assist would never recommend this airline to anyone and for sure will not fly it again

The plane was very clean, the flight attendants were chipper and accommodating. It was roomy

There was extremely long wait times to check in my bags and pass through TSA. I almost missed my flights on several occasions.

I didn’t have enough time to catch my connecting flight and had to use a different Airline. I will be requesting a refund.

There were a lot of issues at the gate in Atlanta — which caused delays in boarding and getting to our destination. The aircraft and crew were excellent.

It was fine. The flight was delayed for 3 hours. I had things scheduled in Detroit, and I let a lot of people down by not being there on time.

First time experience and though you'll pay for *everything* meaning bags, water/snacks, even a question with a service agent - - all in all, not a bad experience whatsoever.

Long lines, rude staff, everything that's offered you have to pay for.

Among the worst flights I’ve taken. Never again. Staff was horrible across the entire Frontier workforce. Flight attendants were legitimately yelling at and arguing with each other while on board - toxic environment (really guys? at work and in front of customers no less?). Frontier intentionally assigned my partner and I (who booked together) to opposite ends of the plane despite plenty of seats together - straight up predatory practices to take people’s money. Seats are legit the absolute worst. Not even free coffee. Absolute garbage airline with wild hidden fees and the worst staff in the business. They will for sure have a deadly accident soon. Never again, not for any where not for any price.
