Do you have any tips for my flight to Williamson?

  • What you pack in your hand luggage can be the difference between a comfortable flight, and a less-than-pleasant experience. Start with the important stuff, like your passport (or a valid ID) and your travel documents. Once they’re safely packed, put in any medications you might need. Next, think about comfort. Earplugs, a neck pillow and the latest bestseller will help the hours fly by while you’re cruising at altitude.
  • There’s a list of items you shouldn’t pack in your carry-on baggage too. Explosives, sharps and flammables are strictly prohibited in the cabin — they often include aerosol cans, flares, box cutters and razor blades. Some sporting equipment, like martial arts weapons and baseball bats, are also not allowed in your hand luggage. Check your airline’s website for details about what you can and can’t bring on board.

What to wear on a flight:

  • Whether traveling long or short-haul, layering up is key to staying comfortable. Opt for loose, breathable fabrics that will keep you fresh and bring a pullover to cope with any variations in cabin temperatures. Your feet will be happiest in a pair of closed-toe shoes or sneakers.
  • Consider wearing compression socks or tights to help prevent deep vein thrombosis (DVT). This blood clotting condition can be caused by prolonged periods of sitting, especially on long-distance journeys. Doing foot and leg exercises in your seat or wandering around the cabin are good ways to improve your circulation.

How can I get a cheap last-minute flight to Williamson?
Scoring a cheap, spur-of-the-moment flight to Williamson is as easy as having some flexibility with your travel plans.

If your destination has multiple airports, compare the prices of jetting into each of them for the best deal on your airfare.
