Airline reviews

The flight attendants in First Class were mediocre at best. They did not take our tray away until we were about to land and only did so when I press the call button. The United person at the United Club was asked to get us our boarding pass since we missed the flight due in Chicago. She argued that we did not have seats on the flight given to us in Moline. Furthermore, she was adamant that we did not have a First Class ticket. After I spent much time with her trying to show we were correct, she reluctantly agreed. She was probably the most incompetent ticketing person I have ever met and I have traveled 3 million miles on United plus many additional miles with other carriers. United has definitely deteriorated in more than on way.

Short flight - no food understandable. Flight was delayed for over an hour. Overall, it was good.

We arrived early and finally made it to our gate almost an hour after.

Was a pain having to leave the plane and reboard but glad the plane was fixed

Plane was was better than th YVR to ORD flight but was a fraction of the distance. Fly your better planes on longer distance flights.

Nothing wrong with the flight itself. But due to 2+ hrs waiting in immigration and the additional security checkup in O’hare, I nearly missed the flight.

They need to improve their boarding process. Group 1 and/or paying first class passengers shouldn't be in the middle of boarding process

late departure due to some unspecified issue with ventilating the cabin. They got it running but it was FREEZING for the whole flight. I asked for a blanket but they didn't provide one. They could not turn up the heat. it was quite miserable.

I still prefer Delta, but Delta doesn’t fly to State College PA.

Everything was fantastic. Modern plane. All the amenities! Although the paid snacks and meals are pure robbery. Like i understand airlines need to make money, but 11$ USD for an overnight oats with some nuts in it and barely any pieces of apple.... Highway robbery

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.

Crew very helpful, weather made the flight less than optimal.

Flight was fine. I just forgot how smaller planes have more dips and seats in high winds.

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.

Information regarding the delayed flight could have been better, and the Contour airlines app needs some serious updates. But overall, the crew was great and the flight was uneventful.

The boarding procedure is as easy and the crew very friendly.

This is a great airline for what it is. You get 1 checked bag included per passenger and the space per seat is incredible. It’s an E135 aircraft that is configured to seat 50 people but they have removed 20 seats and only seat 30 so you have a ton of legroom. They are doing things right and have a great product for what it is. It’s not going to knock your socks off in experience overall but the plane, although dates, was nice and clean and the crew was great. The flights were on time and super efficient. Will travel them again. I am a frequent traveler on all the larger airlines and this was just as good as any regional carrier, if not better. I expect big things out of Contour in the years to come.

Not waiting on the tarmac for an hour and 20 minutes

Most of the delay was due to weather which is not what was at issue here. One delay was due to a missing flashlight and in the end the flashlight was actually found on the plane. The entertainment system is very limited. Live TV options offer only a few channels that are not very appealing. Boarding and deplaning are always difficult. It just takes too much time to get on and off the plane. On the plus side, I missed my connecting flight, but was easily able to book a later flight from the app while enroute.

You were more on time than United. I'm so over united delays.

The meals were mediocre and the alcohol selection was poor. I enjoyed the selection of movies and other entertainment.

I chatted with the captain before the flight, and similarly during the welcome announcement, he warned of a turbulent flight that may impact the in-flight service. However, once at altitude, he announced that the weather changed and he immediately turned off the seatbelt sign. But it appeared the cabin crew had already decided to take off this flight. They remained seated and then just chatted in the galley. The flight was fully catered, but only first class received service.

My flight attendant was attentive! The elderly person next to me was flatulent and the flight attendant could see that I was in distress and brought me some face masks

My boarding pass wouldn't pull up in the app very easily and had to really dig through my email. That caused a delay in TSA..

I had a TERRIBLE experience with the AA crew. I believe it was disability-related. It’s unlikely I will fly AA again.

Baby cried a lot. Nothing anyone could do about it. Just part of flying.

The flight crew was fantastic! Which the seats had a small TV.

The flight was delayed till next day ! They kept delaying every 30 minutes then after 3 hours they delayed it till next day. We kept waiting in line standing more than an hour to get the hotel and meal vouchers. There was no communication at all. Everything was bad

Communication could be better but the staff and crew were over the top friendly and helpful, The flight itself was smooth.

flight was cancelled literally at 10pm the night before an early morning flight with hardly any time to reschedule. Will never book with kayak again.

My flight was cancelled 12 hours before takeoff. I was not able to reschedule another flight to make connections and had to cancel the entire trip. The ticket that was supposed to replace the cancelled flight had no boarding pass and I was unable to get one at the airport so I was denied access to the rescheduled flight. I was refunded but I missed my daughter's birthday.

I had a family emergency and couldn’t make the flight, and they wouldn’t let me cancel/refund it (a *month* ahead of time), were especially difficult with me on the phone, and wouldn’t let me even so much as reschedule the flight or get credit.

Flight was cancelled, communication was poor and should have canceled flight much earlier.

Flight was cancelled twice. Moved four more times. Probably the least timely and poorly run airline I have ever experienced in my life. I have traveled hundreds of times to dozens of countries and this one takes the cake.

Excellent crew, good flight. Flight was delayed about 1 1/2 hours though.

Pros: "The ground crew and flight crew were great."
Cons: "Would have appreciated easier steps (lower risers) for boarding. Arthritic knee makes it hard for me to manage the high risers between steps. Also having armrests would have made the flight more comfortable."
Pros: "I loved the small craft and easy boarding."
Cons: "Flight is a little slower with a smaller plane, but that was expected."
Pros: "So fast and friendly crew. So much easier to fly to Morgantown, instead of driving. Plus the views from above are so great."
Cons: "Flight could not be better for a commuter connection."
