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.

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

Not on time. Taxied around the airport for 30 MINUTES! The pilot never said a word. Ai

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.

My luggage is missing and contour is doing a terrible service helping finding it. Unbelievable and the worst experience ever. I would love get my money back.

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!

Quinoa chocolate cookies are my favorite! Would be nice to have internet service like American

Better management of the boarding process. Is there any way you could forward all the window seats first? That's the Way Reno Air used to do it, and they had the fastest boarding in the industry!

Old plane, no amenities. Very abrupt landing. Unnecessarily long taxi time.

We were delay because so many bags needed to be gate checked and it was disappointing not to have outlets in the seats for such a long flight.

Raleigh to Chicago was OK. The problem was Chicago to Lincoln. Flight was delayed 4 hours. Give them credit for the updates and reason why it was delayed

boarded early to only find out that flight would sit at gate for 45 min to an hour. Landed in chicago and sat on runway for over an hour before got to gate. Total delay was extensive for a 45 min flight door to door.

Weather delay in Chicago?. No sense of urgency to make connection in Chicago for our connecting flight that wasn't delayed. Connection was missed.

It was fine, definitely older planes with no charging or anything. There’s no entertainment set up on board, but it is nice that they allow you to access the in flight entertainment from your phone without having to pay for the Wi-Fi and they do offer free texting.

The plane was in Moline all night. Consequently, we assumed an on time departure at 8:15am. Unfortunately, and as is the normal case with United in Moline, we departed 2.5 hours late. When the crew came, it was discovered that there was very little heat in the plane. Seems this should have been checked hours before the crew arrived. Then when we boarded and the plane was to be de-iced, the United de-icing truck was not working! We awaited the American Airlines truck. All of this caused us to miss our connection in Chicago. My suggestion is never take United Airlines flight from Moline. We have been disappointed 80% of the time and have vowed to not take United again from Moline.

The flight was delayed instead of leaving at 11 it left at 12.20

I was truly shocked at how poor this flight went. The crew was not friendly during the checking process. The asked for people to gate check and were rude about it. They didn't handle my luggage with care. When I got to my seat I noticed a large section of the ceiling vent area was, no joke, TAPED TOGETHER WITH CLEAR PACKING TAPE! To add insult to injury, the back rest button was disabled on my seat and all the seats I could see. The wifi, never connected for me, despite troubleshooting it for a while. I did everything from restarting my wifi/phone to forgetting the network and restarting the app. But that didn't stop the mandatory 2 ads from playing every single time. Even the bags took over 45 mins to arrive at the carousel. Everything about this flight was a flop and I am beginning to notice that some of these events are becoming a trend. Perhaps it's time I switch loyalty programs.

It would be helpful to be able to download an eticket from either American airlines or Cathay Pacific; not just Cathay Pacific.

Another American Airlines flight, another significant delay. At least this one wasn't canceled like many others have been. This time we sat on the runway at LaGuardia for 2.5 hours. By my count that is 7 American flights the last three months that have been delayed 2 hours or more or canceled entirely.

There was no clear update on the flight until last minute and made it an hour delay. No clear flight aircraft or incoming flight which we will be boarding. We would plan accordingly for our connecting flight. This is one one the worst service, I also had to buy an another ticket with different ai carrier. American airline was not letting me plan my trip, made us just waiting. Not a good service at all.

The plane was delayed after we boarded - although they sent an email to my work email (which I did not get until later) there was no announcement from the PA about the delay in flight. Fortunately, they made up the time in the air and we landed around the original time.

My luggage was lost at some point during my layover between Chicago and LHR. I landed Tuesday morning, and did not get it until Thursday night. Ironically, the people at the ticket desk had added a “priority” sticker to my tracking tag.

My experience was fine, with one surprising exception. After leveling off at cruising altitude, the main cabin flight attendant made an announcement that he had a cold, so he would not be coming through the aisle to provide cabin service. He claimed this was in consideration of his health and safety and ours. However, if passengers wanted a beverage, he invited them to come to the back of he plane, where he would provide service. I understand that a flight attendant's primary responsibility is to ensure passenger safety, but a secondary role is to provide service. If this flight attendant was too sick to perform his duties - and if he truly cared about passenger health and safety , as he claimed - he should have stayed home and called in sick, rather than exposing the cabin to his germs.

The flight was delayed multiple times. Breakfast was not served and only an apology given and statement that we could find better pastries in Paris. Seats were extremely narrow and uncomfortable.

We waited over 30 minutes for a gate in Chicago and more than 15 minutes for the doors to open. Cookies were missing from the menu.

This flight is frequently delayed. The connections seemingly are more frequently delayed. I’ve missed connections as a result twice on the same route to charlotte then Charleston. Final destination arrival has been the next day, twice in a row. No pilots, no crew. Too many excuses. Unfortunately, my days with American are over.
