Frequently asked questions

Is it cheaper to buy a plane ticket from MTH to EYW last minute?
Booking your trip from MTH to EYW last minute could save you cash if you luck out and find a good deal. However, fares don't usually get cheaper as the departure date nears. If you wait, flights could also be sold out or the best seats long gone. If you'd rather play it safe, book well ahead of your departure date. Keep in mind that some of the best deals can be found up to a year in advance. If your favorite airline hasn't released its fares yet, check back regularly as deals are constantly updated on Expedia.
Can I change the date of my flight from MTH to Key West Intl. Airport?
Quickly and easily make changes to your MTH to Key West Intl. Airport journey via the Expedia Trips portal. But before you make any amendments, check the fare rules in your itinerary to learn what the carrier will let you do and what charges may apply. Some carriers have a change fee per person, on top of any difference in ticket prices. But if you booked in the last 24 hours, you may be able to cancel for free and book new flights. You can also take a look at our Customer Service portal to find the answers to your questions and to connect with our Virtual Agent.
