Do you have any tips for my flight to Alpine?
No matter where you're coming from, flying can be an enjoyable experience if you prepare well enough. Follow these handy tips that will get your Alpine escape started on the right foot. What to pack in your hand luggage:

  • First and foremost, pack in your passport, official ID, cash and daily medications. Next, you'll need some in-flight entertainment to help pass the time. A juicy book and a tablet crammed with your favourite movies are some terrific options. If you hope to catch forty winks, a quality neck pillow and a pair of earplugs will also be useful. Finally, leave some space for a toothbrush and some cleansing wipes so you'll hop off the plane feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

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

What to wear on a flight:

  • You'll want to go for comfort over style. Prepare for changes in cabin temperature by dressing in layers, and opt for easy-to-remove shoes like sneakers.
  • Deep vein thrombosis (DVT) is a potential risk on long-haul 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 Alpine?
The answer is simple — be prepared. We've pulled together some tips and tricks for a hassle-free trip through airport security. Watch out Alpine, here you come:

  • Be sure to have your ID and travel documents easily accessible. They're the first things you'll be asked for by security.
  • Your coat, belt, keys and other small items, like your earphones, will be required to go through the X-ray machine. Make the whole process faster by removing them before your turn.
  • All your electronic devices, including your phone and tablet, are also required to be separately scanned.
  • Don't forget to remove gels and liquids from your carry-on luggage. They usually need to be sent through the X-ray machine separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-close bag.
  • Slip-on shoes are a sensible footwear choice as you're less likely to have to remove them when going through security. Safety boots and other heavy shoes are usually subjected to additional screening.
  • Airlines will not allow any sharp items or pocket knives in your hand luggage. If you must bring these kinds of items, put them in your checked baggage.
