Do you have any tips for my flight to Cross Keys?
Depending on where you're coming from, your flight to Cross Keys could be completely painless or it could go on forever. We've rounded up some useful tips that will help you start your next unforgettable escape on a positive note. What to pack in your hand luggage:

  • Travelling on a plane can be a great experience if you pack the right gear. First of all you'll need basic toiletries, such as deodorant and a toothbrush, a clean pair of socks and a good read. Next, leave space in your hand luggage for your electronic gadgets, chargers, your medications and maybe a comfy neck pillow as well. Lastly, and most importantly, be sure to bring your passport, travel papers and some cash.

Do not pack the following items in your hand luggage:

  • Squeeze all your full-sized bottles of hair gel and hairspray in your checked luggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by security. Pointed or sharp objects, like your beloved Swiss Army knife, and dangerous products which are explosive or flammable, such as flares, chemicals agents and fuels, are also banned.

What to wear on a flight:

  • Your priority is to be as comfortable as possible. Choose shoes that are easy to slip on and off, dress in loose, natural fibers and remember to bring a sweater in case you get chilly in the cabin.
  • Deep vein thrombosis (DVT) can pose a risk on long-haul flights. It results from blood clots forming due to poor circulation and inactivity, 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 Cross Keys?
The secret is to be organized before you arrive at the security gate. That way, you'll be boarding that plane to Cross Keys in next to no time. Follow these tips and get your trip off to a terrific start:

  • Security personnel first need to make sure that you have a valid passport and matching travel documents before anything else. Have them ready to show.
  • Next up, both you and your hand luggage must be X-rayed. To make the process quick and painless, take off anything that might set the alarms off. Items such as your coat, belt and earphones need to go through the machine.
  • Electronic devices like laptops and phones will also have to go on a tray to be scanned. Don't worry though, you'll be back online soon enough.
  • Remember to remove liquids and gels from your carry-on luggage. They usually need to be sent through the X-ray scanner separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a single quart-size (one litre), clear zip-close bag.
  • Choosing your footwear wisely can save you several minutes. Hiking or heavy-style boots are often required to be removed and separately scanned. Lightweight sneakers usually aren't.
  • Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, put them in your checked luggage. They won't be allowed on board.
