Seats are so hard on the but that it's hurts to the bones for a few days...!! I travel a lot, and this is the only airline/aircraft that this occured. Also even checking in online, and gaving your boarding, they managed to get us to go to the counter to tag our carry ons...

Nothing.

Inexperienced crew. Had to circle the departure airport for 1.5 hours and then land again due to a mechanical issue. They didn't tell us what was going on exactly. Sat at the gate for another 40 minutes. Finally departed. Everyone on boar missed their connections. I personally missed a whole day of my European vacation due to this error. Stuff happens from time to time but it would have been nice for them to have handled it better.

My first and last flight on the CRJ 9. It's much less comfortable than a prop plane, for a 90 minute+ flight.

Pretty basic one hour flight so there's not much to complain about or praise about. I got some sleep which was good.

The crew had their general Dutch aloofness on form. Chatted to one of the stewardesses in Dutch up until she saw I had a British passport then she decided she could only speak English to me.

We have been on 6 flights over the last 8 days, all with Delta and we have already started telling people how wonderful the service was. Sherry on this last flight was amazing, working so hard all by herself as our flight attendant. We were very impressed. And the pilots all came out to say goodbye and thank you. All very nice...esp for me who needed some wheelchair assistance. We will certainly fly with you again in the future.

Smaller plane but ok for short flight

The onboard crew were lovely.

Stood at check in for over 30 mins with no staff in sight. Boarding was a disaster. Staff was not prepared nor organized and the crowds were unbearable. Upgraded seats were laughable and not worth an extra $60. Food was mediocre. Entertainment would have been good but GE touchscreens are so old, they were difficult to work.

The seats were uncomfortable. They were hard and so narrow I had to sit crooked in the seat to keep from getting banged into by the service carts and every person going by to the bathrooms. I'm not tiny, but I'm not huge either, it was just overcrowded. It was also very hot in the airplane the entire way from Phoenix to Spokane. My husband, who is always cold, was even hot.

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.

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.
