The waiting area at the Boston airport is poor. It is very small, rundown and with limited access to refreshments. It's ok but certainly not a selling point.

They have good entertainment system and library

The plane delayed for almost 90m due to a mechanical issue. Of course, we missed our connection in Vancouver. Upon arriving in Vancouver, there was no help at all or guidance. Customer support desk was manned by one agent even in the presence of long queues.

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.
