Lately ORD airport struggles in general often having ground stops. Construction extends travel back to airport so allow 2 hrs. Over past few months, experienced far few delays on United than AA.

Give adequate time of more than 2 hours for your connection in Chicago O’Hare .. The terminals are not that far apart but still if it’s checked out and check in again process that involves TSA security screening again , 2 hours may not be enough ..

United delayed my luggage twice on flight to Europe (first flight was for an important event) I carry 2 days of clothes in my backpack no matter who I'm flying with United especially so. No less than 2 hour layover to decrease possibility of loss/delay of luggage. Second EU trip my luggage was left in Germany even though my layover was just over 1 hour. Select layovers of 2+ hours although Unite will sell flights with 40 minutes layover (nonsense). 1 hour layover was not enough to transfer luggage in FRA. The last scan was 30 minutes after the flight left (SMH).

Make sure when you go from one airline to another that your bag is marked properly so they can get it on the right damn airplane. I did that and it still didn’t make it.

Arrive early, grab a bottle of soda before getting on the plane and open it in the terminal. If you wait until flying the pressure will decarbonize the drink.

Not many amenities at the terminal. I would suggest grabbing anything that catches your eye before you get all the way down. There weren't a lot of Alaska flights out of Chicago, and we were at the extreme end of the terminal.

Make sure there's enough time between connections to go through customs and recheck your luggage. They will not let you proceed so you can't even try to run and catch the flight if you want to.

The flight is long, at over four hours. I would try to get a window or aisle seat to be more comfortable. I would check with other airlines that allow you to choose your seat even if you are in the economy section. I would bring your own food on the plane as the service was sometimes sketchy.

The flight is short enough that full beverage and snack service is limited or not offered at all. On this flight, we were offered orange juice or water. It makes sense that they can't do the full service, and doesn't bother me, but it's something to be aware of.

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!

It was easy, efficient from start to finish. The flight attendant was amazing. Smooth ride. It was just perfect.

We had a great experience on both of our flights! Crew was great…..the ride was smooth…and checking in was easy. We will definitely fly with them again.

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

Great flight, professional crew, convenient and interesting nonstop routes. Had trouble with getting precheck listed on boarding pass, but found that customer service was remarkably responsive via email — unheard of with other carriers. A great experience overalll.

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.

Poor communication, flight was delayed for preventable reasons. I missed my connection.

No meal service to the back of the plane as it started late or was too slow to get it out before it was time to land.

Terrible, if possible won't be flying again anytime soon!

Efficient boarding and early departure. Very smooth flight. Early arrival in ATL. Great flight.

Smooth and easy boarding, comfortable for the entire 5 hour flight, and the seat back entertainment was great! I appreciated all the features, from location info and maps, movies, the ability to connect with Bluetooth headphones, and good selection of movies. Food was good, normal airline snacks (I didn’t purchase anything)

Awful. No counter attendants. No dinner offered due to delays.

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

Delays experienced in boarding/take off due to incoming plane delayed. However, the boarding time/depart time in the app was significantly delayed in providing these updates. Usually not updated until an hour after we should have already boarded. Poorly managed.

Moved to earlier flight which unexpectedly had maintenance issues initially indicated as quick fix to ultimately plane changes. Moved back to original flight, also delayed. In all cases customer updates and communication very unclear, no updates on drivers for delays.

Typical AA - late by 90+ mn. Gate changed twice... Changed the departure time 6 times No explanation, no communication on reasons for delay I travel with AA twice a year... and it is consistently very poor.. I will continue to use AA only when i have to.

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.
