CLE
Mediocre 2.0

Pros: Nothing, to be honest.

Cons: Terrible boarding process (boarding groups one and two together for the first time, so even though we were group two priority, we did not get on until the middle of three and no overhead bin space left). There was no snack/beverage service. We did get a tiny bag of pretzels and were supposed to get either water or juice, but we never saw a beverage. Also, my seat's entertainment did not work. The worst was the HORRIBLE TINY ECON SEATS!!! Unless you are a child or a small woman/man, I would avoid this flight if at all possible. I have never been so uncomfortable on a flight, and I fly a dozen times a year for the last 25 years.

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.
