  • Bundle your flights, hotels and car rental into a competitive package deal. Save your money for things you're really excited about, like discovering every corner of Fort Irwin.

There's nothing as exciting as jetting somewhere new, but it's smart to be prepared. This list of practical tips will help get your journey off to a good start:

  • Whether you print it out at home or use an electronic one, you'll need your boarding pass to step foot on the plane. You'll also need some form of government-issued photo identification. If you're traveling internationally, make sure your passport is valid and you've looked into visa requirements.
  • Make time fly by even quicker on your short hop by packing the right gear. Think a water bottle, snacks and entertainment. If you want your journey to Fort Irwin to go nice and peacefully, throw some noise-canceling headphones in your carry-on bag too.
