Do you have any tips for my flight to Idaho Falls?

  • Get your vacation off to a great start by being well prepared. Pack the important stuff — like travel documents, your passport and any medications you need — first. Next, think about downloading a few blockbuster movies on your tablet for a guiltless binge session. Or, toss in that fantasy bestseller you’ve been wanting to read. Lastly, a snack or two to nibble on and a blow-up neck pillow will go a long way to making your journey as comfortable as possible.
  • It also pays to check with your airline regarding what you can’t take on board your flight. Razor blades, pocket knives, swords and batons are among the prohibited items. Anything explosive, flammable or sharp is generally not allowed in your carry-on. Be sure to pack any sports equipment like baseball bats or tennis rackets only in your checked luggage.

What to wear on a flight:

  • Opt for comfort before fashion when flying. Layer up and wear natural fabrics as they allow moisture and air to pass through and keep you cool. Cabins can get colder on longer journeys, so pack a sweater and always wear sneakers or enclosed shoes.
  • The condition called deep vein thrombosis (DVT) is a risk on long-distance flights. It’s the result of blood clotting due to inactivity and poor circulation. Wandering up and down the aisle and doing leg and foot exercises while seated can help prevent this developing. Wearing compression socks or tights can also help to reduce your risk.

How can I get a cheap last-minute flight to Idaho Falls?
The key to securing a cheap, spur-of-the-moment flight to Idaho Falls is to be flexible. You can land a fantastic deal if you’re not tied to specific travel dates, flight times and carriers. Also compare the prices of flying out of and into nearby airports if that’s an option for you.
Where can I learn more about changing or canceling my flight to Idaho Falls?
Most flights are free to cancel within 24 hours of making the reservation. However, some flights are non-refundable, and you may receive a flight credit from the airline to use for a future booking. For more information, please visit our Customer Service Portal.
