Do you have any tips for my flight to Sunnyside?

  • Get your vacation off to a great start by being prepared. Pack the important stuff — like your passport, travel documents and any medications you need — first. Next, consider downloading some new movies on your tablet or phone for a sans-guilt binge session. Or, toss in that novel you’ve been wanting to read. Lastly, a few snacks and a blow-up neck pillow will go a long way to making your flight as comfy as possible.
  • You’ll also want to check with your airline regarding what you can’t take on board your flight. Batons, swords, box cutters, razor blades and knives are among the prohibited items. Anything sharp, flammable or explosive is generally not allowed in your carry-on bag. Be sure to pack any sports equipment like baseball bats or tennis rackets in your checked luggage.

What to wear on a flight:

  • Whether traveling long or short-haul, wearing layers will help you stay comfortable. Wear loose fitting, breathable fabrics that will keep you fresh and pack a pullover for any changes in cabin temperatures. Your feet will be happy in a pair of sneakers or closed-toe shoes.
  • Reduce your risk of developing deep vein thrombosis (DVT), a blood clotting condition which can be caused by sitting for extended periods, by regularly moving around the cabin. Alternatively, do some gentle foot and leg exercises in your seat. If you’re at higher risk of developing DVT, think about wearing compression socks.

To score a cheap, spur-of-the-moment flight to Sunnyside, it’s important to be flexible. If possible, have some wiggle room with the dates you can travel. It will also help to leave your options open with your airports, choice of airline, flight times and potential stops or layovers.
