Do you have any tips for my flight to Crestline?
Depending on where you're coming from, your trip to Crestline could be a piece of cake or it could go on forever. We've put together some tips that will help you start your next great escape on a positive note. What to pack in your hand luggage:

  • The trick to having a pain-free flight experience is to pack in advance. First up, the essentials: passport, boarding pass, bank cards and any vital medications. Next, bring items that'll help keep you entertained, like your laptop or a good book. You'll also want to pack your chargers, a quality neck pillow and a pair of headphones. Finally, don't forget 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:

  • Double-check that you don't have a pocket knife lurking in your hand luggage. Other banned items include explosive or flammable substances, such as bleach and fuel, and gels and liquids in containers larger than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Your goal here is to feel as comfortable as possible. Opt for a pair of slip-on shoes, dress in loose, natural fibers and remember to take a jacket in case it gets chilly in the cabin.
  • Most travellers are aware of deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity. To reduce your risk on board, drink lots of water, consider wearing compression socks and keep your feet and legs moving.

How to get through airport security fast when flying to Crestline?
It's all about being prepared. We've put together some top tips for an easy trip through security. Look out Crestline, here you come:

  • Be sure to have your ID and travel documents someplace easily accessible. They'll be the first things you'll be asked to show at security.
  • After that, both you and your carry-on luggage will be X-rayed. To make the process quick and painless, remove anything that might set the alarms off. Items like your coat, belt and headphones will be required to go through the machine.
  • All electronic devices, including your laptop and phone, are also required to be separately scanned.
  • Want to bring along your favourite cologne or perfume? No problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, it's OK to bring with you in your carry-on.
  • The right choice of footwear can save you several valuable minutes. Boots are often required to be removed and X-rayed separately. Slip-on shoes are usually not.
  • Airlines will not allow any sharp or pointed objects to come on board with you. If you must bring these kinds of items, put them in your checked baggage.
