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.

You could have NOT left me and my family high and dry by not completing the reservation changes because they no longer have the contract from Phoenix AZ to Moab Utah. There wasn't even a ticket agent for Contour in Phoenix to talk to. Cost my an additional $1600. to rent a vehicle to get my family to Utah. Now I'm left with trying to have someone make it right financially. I'm not optimistic..........

I’ve flown Contour on 4 different flights in the last couple weeks and every one of the flights were significantly delayed. Like over 2 hours delayed. 3 of the 4 were due to maintenance and one was weather, which is beyond their control. If this continues, I will not fly them anymore. It makes me concerned that they don’t have great maintenance practices. The planes are very old and worn out and the interiors need improvement. I do like the amount of space you have between seats for legroom. They also started charging for bags recently, which I think the did when they partnered up with American Airlines as a codeshare partner. American is also a disaster of an airline so I wish they had some agreement with Delta. I am glad they offer a major airline parternership though. That is certainly giving people more opportunities. I won’t fly Contour unless they have a direct flight to where I am going. If I have to connect then I am going to take Delta. The bus at the DFW airport to get on and off the aircraft is a pain and adds so much extra time to your travel experience. I hope this is temporary while they are building a new terminal, but I don’t know.

Short flight so no entertainment and none expected or appropriate. Everyone I dealt with was professional and helpful. A good experience.

Love it. No Frills but better than Spirit No Frills. It's like a simple luxury private plane especially if you've got five or six people on it because then you probably got your own section of the plane.

All the staff were amazing! The flight was quick, everything went smoothly, I have nothing but good things to say about this flight. Thank you Contour!

This was my first time flying with Contour and the Greenbrier Valley Airport. It both were excellent and the price couldn’t be beat!

I felt like a sardine in my seat. We all did. The plane was so small that I hit my head on the roof when I stood up from my seat. The service was good and the crew were nice.

Flight was cancelled, but they got him on an earlier delayed rescheduled one. Arrived Chicago 2 hours later than expected but long layover so it worked.

It’s the only flight connecting Marion to Chicago, I do appreciate that it was available!

The flight was delayed and then less than 30 mins before boarding they cancelled the flight when clearly they had to have known earlier that they were going to have to cancel. There was only one person there available to talk to and all he could do was tell us to call reservations our self. Due to high call volume I waited 2 hours to even get rebooked on a flight to a different city where I would still have to drive 1 hr to my destination, only option for me. While waiting to talk to reservations people were getting emails with new flight info and the flights were days out and sone even a week out. . I did not get compensated in anyway after having spent all day at the airpot, not even a food voucher. Very disappointed, terrible experience.

It was terribly delayed with zero support from united airlines. I reached at 1 am in the night. They did not provide any option to change the flights.

Flight cancelled instead of leaving Friday am now, maybe, leaving Sunday

one of the flight attendants on the Dallas to frankfurt leg was somewhat rude..

Friendliest Flight Attendant I’ve seen since I flew on Southwest Airlines. The whole trip was outstanding…and arrived Early!

A little bit more leg room in premium economy. I am 6’4”.

Sucks ! All three flights I was on this trip were delayed.

When I got our tickets, my husband and I were easily able to get seats together (including a window seat). When we checked in at the airport all the seats were reset and we had to pick new ones, so we couldn’t sit together because there were only middle seats! Ugh that’s the worst. We were back so far we had to check our carry ons which was annoying because I bring an expensive camera that I don’t/cant check so I had to reorganize my items. Once we were seated on the plane we had to wait an hour to take off and they said there was some weather/air traffic in Denver but it was unclear. The lady I sat next to complained that our seats didn’t go back and we both got free complimentary snack boxes which were quite good. I wasn’t going to say anything about the seats, they were the typical uncomfortable kind. It would have been fine if the 2 hr flight hadn’t turned into 3 hrs. Not the best flight but also not the worst.

Food wasn’t very good, old business seating configuration on an old A340

Crew is way too many times on the intercom re explaining the same thing

Nothing. I flew business class. I always try to avoid air Canada because it’s the worst airline and it’s proven on international level. Sad and embarrassing…

I love the e fact that the staff communicated swiftly when my flight was delayed and gate number changed

Delayed flight more than I hour. When boarding we spent some additional time on the plane before takeoff ....

They lost my baggage and I am still struggling to the information and update

It was good, the staff was great, and the food, was as usual, tea and biscuit. Bathroom was clean, and the plane was clean as well.

Boarding was quick and efficient. We arrived at our destination early.

As a first class customer, there was no power the entire flight which limited my ability to work. I find this unacceptable. The first 11 rows on the left side of the plan were out. I was only offered the option to charge my phone which was not the issue because my laptop was out of power. I asked if there was anything that can be done for me, and the answer was, "no". I was not offered any type of compensation for this AA problem which caused me unnecessary stress due to inability to address business issues on an already challenging travel day. Flight attendants tried to reset the power once but that was the extent of their support. Very disappointing for the lack of expected services on a flight. Please contact me with customer focused response to this complaint.

Update to handle the delay was very bad, crews no smiles or welcome or thanks. Don’t care attitude

Everything was on time, we arrived early, everything worked well.

3hour delay In the last 3 months i had 3 flights and 2 of these had a more than 2:40 hrs delayed

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.

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

Very well recently! Frontier is improving and less harrassing customer on luggages! Positive!

Terrible. The canceled my entire flight when I requested a refund for a trip frontier canceled trip one way.

i was unable to check in the flight. refund requested

Book with frontier airlines with the mentality that they'll cancel your flight, kick you off and lose your luggage. Anything besides that is a win. Compare prices with other airlines (to include luggage) and if frontier is still worth it, book it but know all of their policies.

Would be great if Frontier can Assign Seats together under one PNR

Boarding was organized and flight was on time. Overall very satisfied with my flight.

The boarding gate was in Terminal D, but the Frontier counter was in Terminal E. So I had to move back and forth between terminals to check in my luggage. This was the worst experience that I had in terms of flights.

My departure gate was E10 but no kiosk at E10 for check in & no one to ask. A United attendant helped direct us to E38 for check in. The kiosks at E38 were all malfunctioning. A counter agent had to check us in. We then had to walk back to E10 for boarding. E10 to E38 at DfW is not an easy trek. No where in all the info they sent us indicated there were issues to over come. They can cut only so many corners. Luckily we arrived plenty early to deal with Frontier’s inefficiency.

I was singled out for being a Latina flying solo and the attendants took me out of line to put my luggage in the personal item bin to see if it would fly. Keep In mind I had just flown with the same luggage with no problem not even 5 days ago. The tag was sticking out a bit and the attendant was belligerent about charging me $100. I could not refuse because I didn’t wanna cause a scene. But today I felt targeted and embarrassed. I went online and found out that this happens a lot with this airline and to many minority women.
