Not Cape Air’s fault, but the smoky haze (from fires in CA, OR, NV) diminished some of the long views - vistas were not quite as beautiful as on past flights.

Flight from Havre to Billings was fine, from check in through security and to the flight. Smoke from CA, OR, NV fires really limited the view, but CapeAir did fine with their service

Seats are a little small, but that is to be expected in such a small plane. Other than that, the flight was great.

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.
