Do you have any tips for my flight to Sumas?

  • Wherever you’re headed, flying can be a wonderful experience if you’re properly prepared. Firstly, pack your travel documents, passport and medications. Next, throw in a little extra in-flight entertainment to help make the time fly by. A juicy book and a tablet filled with your favorite series are fantastic options. If you plan on getting some sleep, a comfortable neck pillow and headphones are also worth bringing along.
  • You’ll also want to check with your airline regarding what you can’t bring on board your flight. Razor blades, pocket knives, swords and batons are among the prohibited items. Anything sharp, explosive or flammable is generally not allowed in your carry-on bags. Remember to pack any sports equipment like baseball bats or tennis rackets in your checked luggage.

What to wear on a flight:

  • The aisles of a plane aren’t suitable for a fashion parade. Layer up in comfy clothing and bring a pullover since it can get cool in the cabin during long-haul flights. Sneakers or enclosed, flat shoes are ideal for longer journeys.
  • Consider wearing compression tights or socks to help prevent deep vein thrombosis (DVT). This blood clotting condition can be caused by extended periods of sitting, especially on long flights. Doing leg and foot exercises in your seat or wandering around the cabin will help improve your circulation.

How can I get a cheap last-minute flight to Sumas?
The key to tracking down a cheap, spur-of-the-moment flight to Sumas is flexibility. You can snap up an incredible deal if you’re not tied to specific carriers, travel dates and flight times. Also compare the prices of flying into and out of alternative airports if that’s an option for you.
