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 liked it better when you were truer to your roots Am paying more for less fun

Southwest was greaat! The most expensive but the least upsetting for those we were flying to see.

I flew twice this week on Southwest, was delayed over 2 hours both ways. From Pittsburgh to Chicago it was due to weather but the gate agents, pilot etc were great at updating everyone. Today from Midway to Pittsburgh the plane had come from an international location, kept getting delayed, no information was given until we were delayed for the third time. It was ridiculous, whoever scheduled that plane to fly to Pittsburgh after didn’t consider a lot of things.

Boarding was easy. The seats are small and fairly uncomfortable

I was supposed to be on a later flight. When I showed up at the gate, the woman working there was extremely helpful getting moved up to this earlier flight.

We had a 5 hour delay on the tarmac in Baltimore

Long layover between flights to Long Island from BWI - need better coordination between flights

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

The new seating arrangement is so over priced for what you get.

This trip did not start off well. The inbound flight was delayed about 20 minutes. Then, after initial onboarding, the passengers had to deplane due to a mechanical problem. That took about 30 minutes to fix and be cleared. Then, reboarding was chaotic. It took a long time to sort passengers and two passengers on standby were ticketed but there was no seat. So, they had to deplane. One of the flight crew was trying to help passengers figure out a place to put their carry-on bags and that took more time. In the end, our scheduled 10:30 am departure did not actually take off until about 12:05 pm CST. The flight itself was long but we got to Houston. Some passengers missed their connecting flights and had to rebook. Not the best of flights I've had.

We were delayed for about an hour from taking off due to traffic control procedures at the destination airport. But once in the air, the flight went well. The crew members were great and provided cabin service despite moderate turbulence during much of the flight.

Short flight, but no drink/snack service. The flights both going and coming were delayed.

Not being stranded in Chicago for her airport to 11:30 tomorrow morning the 3rd

I was fully checked in the prior night and i was unchecked and then didn’t have a seat when I boarded. Instead of an aisle seat, I was out in the middle seat of the very last row of the plane.

In overall it was a good experience, the only down point was that the entertainment screen was working properly.

They lost my luggage, so, not happy. The crew was nice but my suitcases never made it, still trying to find out what happened!

I understand weather is an issue, but making us chase our plane down at five scheduled gates across three terminals in an airport the size of O'Hare was unfair. They'd have probably been better off to leave gates as TBD until the inbound plane is in final approach instead of running us all over the place. Also, props to the consistently-unprepared ground crew in Richmond for once again leaving my lane parked short of the gate because they couldn't have a crew in place on time with 2 hours notice...

cabin crew was OK, food was OK, the trip from the US to Munich was actually pretty bad comfort wise. Noisy aircraft, lights never dimmed even in Business class (night flight) barely sufficient amenities for the price. I have millions of miles with United but TBH American is gaining ground and Delta has always been marginally better then United although on paper United has more longes and cheaper upgrades.

Essy to get on. The hostess gave very little pop, the plane was late getting in, and we are still waiting for our bags. This sucks. :/

The gate got changed several times and the flight was delayed over an hour. Awful experience

American continues to decline in their customer service and its beyond disappointing.

It was an older plane. First Class was not especially roomy or comfortable. It was a short flight so there were no meal but they did offer mixed nuts which used to be normal but now is rare. Crew member was very polite and professional.

Flight to Tampa was delayed taking off due to plane arriving late but no other issues

As previously stated the delay I experienced flying from Wichita to Chicago caused a host of issues. When I finally was able to be booked on the last remaining American flight from Chicago to Cincinnati, the gate changed four times with the last change occurring very near the scheduled boarding time. While I didn't have a problem moving from gate to gate, I did notice and make note of others that had mobility issues and had to move each time for the gate change.

Maintenance took a very long time and then we were in a holding pattern. While a one-off maintenance issue is standard, there were delays on both of my flights for this trip based on maintenance issues with the planes, which delayed both flights over 45 minutes. Thankfully, I didn't have any connections but it wasn't an experience that would make me pick AA if I have other options.

No Snacks or Entertainment. The flight was short, snacks should still be given.

See prior comment about how Kayak mishandled my reservation and delayed my arrival by 6 hours.

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

Delayed an hour due to operational issues. Minimal apologies or care for the significant inconvenience caused. Landed at nearly 1am and they still couldn’t find ground staff to get us off the plane promptly.

The flight was a big joke very uncomfortable I had a horrible experience and I will never fly with them again everything about the flight was bogus and I’m not happy with it at all this experience makes me not want to fly ever again

Pricing, boarding time communication, over priced baggage and overall service is lacking, seating unconfortable

Flight attendant was all so sweet and pilot got us to our destination safely and on time

They cancelled our flight. 2 hours before we were supposed to take off and offered us nothing! We got our money back and that was it. No other flight to get to our cruise no working with another airline or with us to get there. Terrible customer service, no apology.

we boarded the plane and then sat for OVER AN HOUR on it, first waiting for fuel and then the crew timed out. the flight kept getting delayed longer and longer, a 9:30pm flight is still on the ground at 1:15am.

The airplane rattled near the left wing as if several screws were loose. Then after we landed in Fort Lauderdale, we had to sit and wait on the runway for quite some time. It was very scary and TOTALLY unacceptable!

Smooth flight staff very friendly and we arrived 15 mins earlier

I was in the airport when I'll check the status of my flight and it was canceled and without any reason. The worst of the worst ...

We get stuck in the plane when landed during 45min and no communication from the crew People were listening to their phone and music out loud and nobody told them anything I definitely want stop booking spirit flight it is a disaster

Good: It was cheap and they got us to our destination safely. Not so Good: Gates experience with many, many nauseatingly (almost) threatening announcements about bags size and how much they were going to charge us if our bag was too big, even to the point of having a gate agent roaming around through the passengers eyeballing bags size and making people go check their bags in the sizers.

The crew acted like they had never done this and kept barking passive aggressive orders at people. + the security line + the delay + sitting on the tarmac for 2 hours + none of the apps or signage updating with correct times

More inflight connection. And leg space is horrible. And the paying for baggage I'd ridiculous!!!

My flight was originally from SAT to MCO connecting from MCO to ORD. We got diverted to ATL and than Frontier staff there was sooo un helpful first they said they couldn’t give us any accommodation since our flight first got delayed that cancelled and now it’s 221am and I am still in ATL since they said they need to create a new flight my final destination is ORD and I have been delayed twice and cancelled. With no real help the frontier app didn’t work no email updates over all such a horrible experience

There's no seats that lean back with little leg space i wad uncomfortable the entire flight. Your charges for extra baggage is despicable and costly!!

Remind customers of the need to have passport or new ID for boarding.

Flight was canceled. Most upsetting was message from Kayak, stating that the flight was canceled and click with Kayak for details regarding rebook, refund details. THERE'S NO INFORMATION PROVIDED BY KAYAK EXCEPT THAT FLIGHT IS CANCELED. AND NOW THIS SURVEY TO FIND OUT HOW WAS THE FLIGHT !!!!!!!

The flight never took off and we spent 7 hours at the airport

Gate not determined until I got to the airport - hard to plan the trip to the airport.

Our flight was canceled. I will never use Kayak nor Frontier for travel again. The entire experience was a headache.

Frontier.. nickel and dime add-ons. Flight late, on time, late again, last minute gate change, arrival gate required a shuttle to the terminal. They sure keep you guessing.. if you like a little chaos and airport anxiety, this is the airline for you!
