Do you have any tips for my flight to Fort Irwin?
Depending on where you're coming from, your trip to Fort Irwin could be as easy as pie or it could go on forever. Here are some handy travel tips that will help you start your next great adventure on a positive note. What to pack in your hand luggage:

  • Firstly, and most importantly, pack in your passport, travel docs, cash and daily medications. Next, you'll want some entertainment to while away the hours. A thrilling book and a tablet crammed with your favourite movies are good options. If you hope to catch up on some sleep, a comfy neck pillow and some earplugs will also come in handy. Finally, make room for a toothbrush and some deodorant so you'll step off the plane feeling fresh and ready to go.

Do not pack the following items in your hand luggage:

  • Leave all your full-sized bottles of shampoo and hairspray in your checked luggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by security. Pointed or sharp objects, like your trusty pocket knife, and dangerous products which are flammable or explosive, such as flares, chemicals agents and matches, are also not allowed.

What to wear on a flight:

  • Comfort should be your priority when deciding what to wear on board. Loose, breathable clothing is a smart option, as are flat, closed-toe shoes.
  • Most travellers have heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of inactivity. To minimize your risk on board, stay hydrated, consider wearing compression tights or socks and move your legs and feet often.

How to get through airport security fast when flying to Fort Irwin?
As seasoned travellers know, the secret is to be well organised before you reach security. That way, you'll be boarding that plane to Fort Irwin in no time flat. Follow these tips and get your holiday off to a terrific start:

  • Keep your travel documents and passport handy. They're the first things you'll be asked to show at security.
  • After that, both you and your carry-on luggage must be X-rayed. To make the process quick and painless, remove anything that might set the alarms off. Items like your coat, belt and earphones need to go through the machine.
  • Your electronic devices like laptops and phones will also need to go on a tray to be scanned. No need to worry though, you'll be back online before you know it.
  • Can't travel without your favourite hand cream? As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, it's OK to bring with you in your carry-on.
  • The right choice of footwear can save you several precious minutes. Boots and heavy shoes are often required to be removed and X-rayed separately. Lightweight sneakers are usually not.
  • Airlines won't allow any sharp items or pocket knives in your carry-on baggage. If you need to bring these kinds of items, pack them in your checked luggage.
