Do you have any tips for my flight to Crystal Lake?

  • Get your trip off to a wonderful start by being prepared. Pack your passport, travel documents and medications first. After that, consider downloading the latest movies on your tablet or phone for a guilt-free binge session. Or, bring that thrilling bestseller you’ve been wanting to read. Lastly, a few tasty snacks and a soft neck pillow will help make your flight as comfy as possible.
  • It also pays to check with your airline regarding what you can’t take on board your flight. Razor blades, pocket knives, swords and batons are among the prohibited items. Anything sharp, flammable or explosive is generally not allowed in your carry-on bag. Don’t forget to pack any sports equipment like ski poles or baseball bats only in your checked luggage.

What to wear on a flight:

  • The aisles of an aircraft aren’t designed for a fashion parade. Layer up in comfortable, loose-fitting clothing and bring a pullover since it can get cool in the cabin on long-haul flights. Enclosed, flat shoes are the best type of footwear for longer journeys.
  • The condition called deep vein thrombosis (DVT) is a risk on long-haul flights. It’s the result of blood clotting caused by inactivity and poor circulation. Wandering up and down the aisle and doing foot and leg stretches while seated can help prevent this developing. Wearing compression socks or tights can also help to lower your risk.

How can I get a cheap last-minute flight to Crystal Lake?
Scoring a cheap, last-minute flight to Crystal Lake is as simple as having some flexibility with your travel plans. Leave your options open with your choice of airline, travel dates and flight times.
