Do you have any tips for my flight to Cascade?

  • What you pack in your carry-on baggage can make the difference between a comfortable flight, and one that wears you out. Start with the essentials, such as your passport (or a valid ID) and your travel documents. Once they’re safely packed, put in any medications you might need. Next? It’s all about comfort. A neck pillow, noise-canceling headphones and a good book will help the time fly by while you’re soaring above the clouds.
  • Don’t forget there’s also a list of prohibited items for your hand luggage which differs between airlines. Generally, avoid packing anything flammable, sharp or explosive. This includes things like box cutters, razor blades, flares and aerosol cans. Sports equipment like baseball bats, and objects that could harm passengers, such as batons and swords, are also banned from the cabin.

What to wear on a flight:

  • Choose comfort before fashion when flying. Layer up and wear natural materials as they allow air and moisture to pass through and keep you cool. Cabin temperatures typically get cooler on long-haul flights, so pack a pullover 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 poor circulation and inactivity. Walking up and down the aisle and doing foot and leg exercises while seated can help prevent this developing. Wearing compression tights or socks also helps reduce your risk.

How can I get a cheap last-minute flight to Cascade?
The key to picking up a cheap, spur-of-the-moment flight to Cascade is to be flexible. You can increase your chances of landing a fantastic deal if you’re not tied to specific travel dates, flight times and airlines. Also compare the prices of flying out of and into alternative airports if that’s an option for you.
Where can I learn more about changing or canceling my flight to Cascade?
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.
