Do you have any tips for my flight to Louisiana?

  • What you pack in your carry-on luggage can make the difference between a comfortable flight, and a restless one. Start with the most important stuff, like a valid ID (like your passport) and your travel documents. Once they’re packed, throw in any medications you might need. Next? It’s all about the comfort factor. Earplugs, a quality neck pillow and a good book will help the time fly by while you’re cruising at altitude.
  • You’ll also want to check with your airline regarding what you can’t take on board your flight. Utility knives, razor blades, swords and batons are among the prohibited items. Anything sharp, explosive or flammable is generally not allowed in your carry-on baggage. Be sure to pack any sports equipment like tennis rackets or baseball bats in your checked luggage.

What to wear on a flight:

  • Whether traveling short or long-haul, layering up is key to flying comfortably. Wear loose, breathable fabrics that will keep you cool and pack a sweater for any in-flight cabin temperature variations. Your feet will be happy in a pair of closed-toe shoes or sneakers.
  • Reduce your risk of developing deep vein thrombosis (DVT), a blood clotting condition which can be caused by sitting for extended periods, by regularly walking around the cabin. Alternatively, do some gentle lower limb exercises in your seat. If you’re at higher risk of developing DVT, think about wearing compression socks or tights.

How can I get a cheap last-minute flight to Louisiana?
Picking up a cheap, spur-of-the-moment flight to Louisiana is as easy as being flexible with your travel plans. Keep your options open with your travel dates, flight times 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.
