Do you have any tips for my flight to Sterling?
Depending on where you're coming from, your journey to Sterling could be a breeze or it could drag on forever. We've pulled together some handy travel tips that will help you start your unforgettable escape on the right foot. What to pack in your hand luggage:

  • The secret to having a hassle-free travel experience is to pack in advance. First up, the essentials: passport, boarding pass, cash and any vital medications. Next, take on board items that'll help keep you occupied, like some electronic devices or a magazine. It's also smart to bring your chargers, a quality neck pillow and a pair of earphones. Finally, be sure to chuck in toiletries like a toothbrush, cleansing wipes and a clean set of clothes.

Do not pack the following items in your hand luggage:

  • While the list of restricted items can differ between air carriers, the general guide to follow is nothing flammable, sharp or explosive. This includes things like tools, metal cutlery, fuel and fireworks. Sports equipment like ski poles, and items that could harm passengers, such as firearms and swords, can't come on board with you either.

What to wear on a flight:

  • Your main aim is to be as comfortable as you can. Opt for shoes that are easy to pull on and off, dress in loose, natural fibers and remember to bring a jacket in case you get cold in the cabin.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged inactivity, can be a risk on long-haul flights. Walk around the cabin and give your legs a stretch or do some simple exercises in your seat to improve your circulation.

How to get through airport security fast when flying to Sterling?
As savvy travellers know, the secret is to be prepared before you reach airport security. That way, you'll be hopping onto that plane to Sterling in a flash. Follow these helpful tips and get your trip off to a great start:

  • First things first. Your passport and boarding pass will need to be shown to security personnel. Keep them within easy reach so you don't hold up the line.
  • Time to strip down. Well kind of. Your belt, jacket, keys and other contents of your pockets, like coins, will need to go through the X-ray machine. Make your life easier by removing them as your turn draws near.
  • For just a few minutes, you'll need to unplug from technology. Your tablet, phone and any other electronic gadgets must also go through the scanner.
  • Travelling with a new perfume or cologne? As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, it's fine to bring with you on board.
  • The right choice of footwear can save you several minutes. Hiking boots are often required to be removed and X-rayed separately. Slip-on shoes 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.
