Do you have any tips for my flight to Defiance?

  • What you pack in your carry-on bag can mean the difference between a comfortable flight, and a less-than-pleasant experience. Start with the crucial things, like a valid ID (like your passport) and your travel documents. Once they’re safely packed, throw in any medications you might need. Next, think about comfort. A quality neck pillow, earphones and a juicy novel will help the time fly by while you’re soaring through the sky.
  • You’ll also want to check with your airline regarding what you can’t bring on board your flight. Utility knives, razor blades, swords and batons are among the prohibited items. Anything sharp, flammable or explosive is generally not allowed in your carry-on baggage. Remember to pack any sports equipment like ski poles or baseball bats in your checked luggage.

What to wear on a flight:

  • Go for comfort instead of fashion when flying. Layer up and wear natural fabrics as they allow air and moisture to pass through and keep you cool. Cabins can get colder on longer flights, so pack a pullover and always wear sneakers or flat, closed-toe shoes.
  • Consider wearing compression tights or socks to help prevent deep vein thrombosis (DVT). This blood clotting condition can be caused by long periods of sitting, especially on long journeys. Doing leg and foot stretches in your seat or walking around the cabin will help improve your circulation.

How can I get a cheap last-minute flight to Defiance?
Booking a cheap, last-minute flight to Defiance is as easy as having some flexibility with your travel plans. Have some wiggle room when it comes to your flight times, travel dates and choice of airline. If your destination has multiple airports, compare the prices of flying into each of them for the best deal on your ticket.
