Do you have any tips for my flight to Crystal?
Depending on where you're coming from, your journey to Crystal could be a piece of cake or it could go on forever. Below are some handy hints that will help you start your unforgettable escape on a positive note. What to pack in your hand luggage:

  • The secret to having an amazing travel experience is to pack ahead. So, let's start with the essentials: passport, boarding pass, cash and important medications. Next, bring items that'll help keep you entertained, like some electronic devices or a few magazines. It's also smart to bring your chargers, a neck pillow and a pair of headphones. Last but not least, be sure to pop in toiletry items like a toothbrush, cleansing wipes and a spare change of clothes.

Do not pack the following items in your hand luggage:

  • Make sure you don't have sharp objects (like a knife or scissors) lurking in one of the compartments of your carry-on luggage. Other prohibited items include flammable or explosive goods, such as aerosol cans and bleach, and gels and liquids in containers larger than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • The aisles of an airplane aren't the place for a fashion parade. Layer up with comfortable clothing and go for shoes that are roomy, flat and easy to pull on and off.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Try to wander around the cabin or do some simple exercises in your seat to promote better circulation.

How to get through airport security fast when flying to Crystal?
The trick is to be organised before you get to security. That way, you'll be boarding that plane to Crystal before you know it. Follow these helpful tips and get your holiday off to a spectacular start:

  • First things first. Your boarding pass and passport will need to be presented to security personnel. Keep them handy so you don't hold up the queue.
  • Time to strip down. Well sort of. Your belt, jacket, keys and other items in your pocket, like coins, will be required to go through the X-ray machine. Make the whole process faster by removing them as it gets closer to your turn.
  • Your electronic gadgets like laptops and phones will also need to go on a tray to be scanned. Don't worry, you'll be back online soon enough.
  • Remove all gels and liquids from your hand luggage. They often need to be sent through the X-ray separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-lock bag.
  • Choosing your footwear wisely can save you valuable minutes. Boots and bulky shoes are often required to be removed and separately scanned. Lightweight sneakers are usually not.
  • Airlines will not allow any sharp objects in your carry-on baggage. If you must bring these kinds of items, pack them safely in your checked luggage.
