Pros: The individual checking folks in at RDU was extremely positive even after the flight had been delayed for hours. The flight crew was very positive as well.

Cons: The plane had just been cleaned so smelled strange on arrival. It would have been better had we not been delayed for hour after hour, then delayed to get to a gate even once we landed.

They forgot about me, then I went up 10 minutes before departure to board, and they told me I was late. It was a mess with overbooking too.

Good 6.6

Pros: Flight was on time. Staff were polite. Flight was totally uneventful (just how we like them).

Cons: We were all required to check our carry-on bags as we boarded as there was apparently no more space in the plane, though once on board, there was space in the overhead storage - I think they did it because it was expedient for them to have us do so. I didn't eat any food so can't really comment on it (gave it "okay" but don't rely on that). The screen for my seat didn't work - no big deal on a short flight but there you go.

She had to walk on her own to the correct gate because they took her to the wrong gate after realizing she wasn’t at the correct gate.

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,
