Do you have any tips for my flight to Crestline?
We've pulled together all the info you need to make your flight as pain-free as possible. Follow our tips and you'll be hightailing it through airport security and having a blast in Crestline in next to no time. What to pack in your hand luggage:

  • First things first, pack your passport, travel docs, cash and daily medications. Next, you'll need some in-flight entertainment to help pass the time. A thrilling book and a laptop filled with your favourite movies are some terrific options. If you plan to take a short nap, a neck pillow and some noise-cancelling headphones will also come in handy. Finally, leave some space for a toothbrush and some deodorant to ensure you touchdown looking fresh and ready to go.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of shampoo and hairspray in your checked luggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 millilitres) won't be allowed on. Pointed or sharp objects, like your beloved pocket knife, and products which are explosive or flammable, such as flares, chemicals agents and fuels, are also banned.

What to wear on a flight:

  • The aisles of a plane aren't the place for a fashion parade. Wear layers and opt for shoes that are flat, enclosed and easy to slip on and off.
  • Deep vein thrombosis (DVT) can pose a risk on long-distance flights. It results from blood clotting due to poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression tights or socks.

How to get through airport security fast when flying to Crestline?
Being prepared before you arrive at the airport will help make your trip to Crestline a breeze. We've rounded up some top tips for a stress-free journey through security:

  • Be sure to keep your travel documents and passport at hand. They're the first items you'll be asked to present to security.
  • Next up is the X-ray machine. Remove anything on you that is likely to set off the alarm. This includes things like headphones or earphones, as well as heavy jackets or coats. They'll all need to go on the X-ray conveyor belt.
  • Your electronic devices like laptops and phones will also have to go on a tray for inspection. Don't worry though, you'll be back online soon enough.
  • Any liquids or gels, such as perfume or hand cream, that you want to bring on board must be no greater than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-lock bag.
  • Choosing your footwear wisely can save you a few precious minutes. Boots are often required to be removed and X-rayed separately. Lightweight sneakers are usually not.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked baggage. They won't be allowed on board.
