从索恩海湾飞往博兹曼，MT（BZN-博兹曼黄石国际）机票含税

Booking your journey from KTB to Gallatin Field at the last minute could save you cash if you’re lucky enough to find a good deal. However, airfares generally don’t get cheaper closer to the departure date. If you procrastinate, flights could also be booked out or the best seats gone (hello, middle seat!). If you’d rather err on the side of caution, book well in advance of when you want to leave. Don’t forget that some of the biggest bargains can be found up to 12 months in advance. If your preferred airline hasn’t released its airfares yet, check back regularly as offers are constantly updated on Expedia.

You can easily make changes to your KTB to Gallatin Field trip through the Expedia Trips portal. Before you amend times or dates, read over the conditions and rules in your itinerary to see what you can do and if change fees apply. Some carriers charge a change fee per person, on top of any difference in fares. However, if you booked in the last 24 hours, you may be able to cancel for free and book new flights. You can also check out our Customer Service portal to find the answers to your questions and to chat with our Virtual Agent.
