Good 6.0

Pros: The flight crew was very helpful and very nice. I was traveling with my 7 month old daughter by myself and the crew made sure I was taken care of.

Cons: When I got off the plane and was waiting for my stroller and car seat to be brought up from the cargo hold, I received the car seat first in good condition. My stroller, however, had the clip busted off that connects the car seat to the stroller and cannot be replaced. So my entire travel system is now unusable. I know this happened on my transfer from Houston to Denver because I had to use my stroller when I got off of my flight from West Palm Beach to Houston and the entire thing was in tact. This is extremely frustrating because this travel system is $450 and is now unusable. And what's even more frustrating is that these items have to be gate checked and are given "special handling" tags when they are checked. The clip that was busted off is a pretty substantial piece so my stroller had to have been handled extremely poorly in order for this clip to bust lose.

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.
