Do you have any tips for my flight to Centralia?

  • What you pack in your cabin baggage can be the difference between a comfortable flight, and one that leaves you tired. Start with the essentials, such as a valid ID (like your passport) and your travel documents. Once they’re safely packed, toss in any medications you might need. Next, think about comfort factor. Earphones, a quality neck pillow and a book will help the hours fly by while you’re in the air.
  • Don’t forget there’s also a list of prohibited items for your hand luggage which differs between airlines. Generally, avoid carrying anything explosive, sharp or flammable. This includes things like razor blades, pocket knives, flares and aerosol cans. Sporting 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:

  • The aisles of an aircraft aren’t designed to be a catwalk. Layer up with comfy clothes and pack a sweater as it can get cool in the cabin during long-haul flights. Enclosed, flat shoes are best for longer journeys.
  • Lessen your risk of developing deep vein thrombosis (DVT), a blood clotting condition which can be caused by sitting for lengthy periods, by regularly moving around the cabin. Otherwise, do foot and leg exercises in your seat. If you’re at higher risk of developing DVT, consider wearing compression socks.

How can I get a cheap last-minute flight to Centralia?
If you want to grab a cheap last-minute flight to Centralia, flexibility is important. If possible, have some wiggle room with the dates you can fly. It’s also wise to keep your options open with your airports, airline choice, flight times and possible layovers or stops.
