Do you have any tips for my flight to Triangle?
Depending on where you're coming from, your journey to Triangle could be simple and straightforward or it could go on forever. Below are some useful hints that will help you start your unforgettable escape on the right foot. What to pack in your hand luggage:

  • A plane ride can be a comfortable experience if you carry the right things. First things first, you'll need basic toiletry items, such as toothpaste, a toothbrush and some deodorant, a clean set of clothes and a few magazines. Next, find room in your hand luggage for your electronic gadgets, chargers, medications and perhaps a quality neck pillow as well. Lastly, remember to take your passport, travel docs and some money.

Do not pack the following items in your hand luggage:

  • While the list of restricted items differs between air carriers, the general rule to follow is avoid carrying anything flammable, sharp or explosive. This includes things like tools, metal cutlery, fuel and fireworks. Sporting equipment like bows and arrows, and items that could injure passengers, such as firearms and ammunition, are also banned from the cabin.

What to wear on a flight:

  • You'll want to choose comfort over style. Prepare for changes in temperature by dressing in layers, and opt for flat, closed-toe footwear like slip-ons.
  • Deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Try to walk 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 Triangle?
The simple answer is — be prepared. We've rounded up some tips and tricks for a hassle-free trip through airport security. Look out Triangle, here you come:

  • Security personnel first need to verify that you have a valid ID and boarding pass before anything else. Have them in your hand, ready for inspection.
  • Your jacket, belt, keys and other small items, like your headphones, will need to go through the X-ray machine. Make the whole process faster by removing them before your turn.
  • Your electronic devices like phones and laptops will also have to go on a tray for inspection. No need to 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 need to be in containers no larger than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-close bag.
  • Choosing your footwear wisely can save you several precious minutes. Hiking or heavy-style boots are often required to be removed and separately scanned. Slip-on sneakers are usually not.
  • Airlines won't allow any sharp objects in your hand luggage. If you must bring these kinds of items, pack them in your checked luggage.
