Flight attendant from IND to Minneapolis must have had a rough evening or bad morning. Service in airplane is usually poor but this one was worse. Bumping most of the passenger when passing, handing drinks behind his back, not smiling.

On time boarding. However we had about an hour departure delay due to de-ice of the plane due to ice storm which just started but I am not complaining about that. I would rather the plane was completely safe for departure.

We have to gate check roller bags due to size of plane. Also, little or no knee room. My knees were pressed into the seat back in front of me.

We boarded on time and we departed on time. We got into Chicago 30 minutes early. We recently acquired a AA credit card and we got 2 checked bags free and priority boarding (Group 5). In today's world your need priority boarding of some sort on AA or you risk not being able to store you bags in the overhead and may have to get it checked free to your final destination. Also, one of our checked bags had a painting in it that we purchased and the bag and painting arrived unharmed. Good job by AA baggage handlers.

Cramped seating. Airlines seem to be moving seats closer together to be able to hold more passengers.

The crew was outstanding, polite, and professional.

Seats were comfortable, but much too crowded. The seating would have been very good for children but for adults it was much too crowded. My knees were up against the seat in front and my back is sore from having to spend most of the trip twisted to try to fit into the small space. Also, my seat was is row 16 and was called a “premium” seat and I was charged an extra $24 for it. I did not find it any different than all the seats around me. What was the extra charge for?

seats are very uncomfortable I know they can make a plane with a wide enough aisle so that you don't get hit in the arm every time the cart or anyone goes past you. why can I ride a twin otter and not need a seat belt extender and need one on American? On the return on the Airbus, the seats were a little more comfortable, but still need seatbelt extender.

The flight attendant was one of the best that we have ever had on this flight. Since we were a late afternoon flight out of O'Hare we did had a departure delay. But the flight attendant served us drinks and snacks while on the ground. And after we took off he came around again and offered us more drinks and snacks. As we departed the plane he even offered us snacks to take with us.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days.
