How to survive the flight to Fort Irwin?
Depending on where you’re coming from, your flight to Fort Irwin could be a breeze or it could go on forever. We’ve pulled together some handy travel tips that will help you start your next unforgettable escape on a positive note.What to pack in your hand luggage:

  • The secret to having a worry-free travel experience is to be prepared. So, let’s start with the basics: passport, travel documents, cash and any vital medications. Next, take on board items that’ll help keep you entertained, like your laptop or a few magazines. It’s also a wise idea to pack your chargers, a quality neck pillow and a pair of noise-cancelling headphones. Finally, be sure to squeeze in toiletry items like a toothbrush, deodorant and a fresh set of clothes.

Do not pack the following items in your hand luggage:

  • While the list of banned items differs between airlines, the general guide to follow is nothing sharp, flammable or explosive. This includes knives, scissors, spray paint and flares. Sporting equipment like ice skates, and objects that could harm passengers, such as guns and swords, are also banned from the cabin.

What to wear on a flight:

  • Your aim here is to make yourself as comfortable as possible. Layer yourself up in breathable clothing and bring a sweater just in case you get chilly. Pick flat, slightly roomy shoes as your feet may swell during the journey. Leave the high heels and heavy hiking boots in your checked luggage.
  • A condition called deep vein thrombosis (DVT) is a potential risk on long-haul flights. It’s the result of blood clots forming due to inactivity and poor circulation. Doing leg and foot exercises in your seat is a great way to prevent this developing. Wearing a good-quality pair of compression socks is also recommended.

How to get through airport security fast when flying to Fort Irwin?
Being organised before you get to the airport will make your getaway to Fort Irwin quick and painless. Below you’ll find some handy hints for a speedy journey through security:

  • Security personnel first need to determine that you have a valid ID and matching travel documents before you’re allowed to proceed any further. Have them close by, ready for inspection.
  • Next up, both you and your hand luggage must be X-rayed. To speed things up, remove anything that is likely to set the alarm off. Personal belongings like your belt, jacket and earphones will be required to go through the machine.
  • For just a few moments, you’ll have to unplug from technology. Your laptop, phone and any other electronic devices must also be sent through the scanner.
  • Any liquids or gels, such as perfume or hand cream, that you want to bring on board need to be in containers no larger than 3.4 ounces (100 milliliters). They must also all fit inside a quart-size (one litre), clear zip-lock bag.
  • Lightweight sneakers are a practical footwear choice as you’re less likely to have to remove them when going through security. Hiking boots and other heavy shoes are usually subjected to extra screening.
  • Airlines won’t allow any sharp objects in your carry-on luggage. If you must bring these kinds of items, put them in your checked luggage.
