Do you have any tips for my flight to Troy?
Wherever you're jetting in from, flying can be a seamless experience if you're well organized. We've put together a list of essential travel tips that will help get your Troy escape started on the right foot. What to pack in your hand luggage:

  • It's simple --- first, pack in your passport, travel docs, wallet and daily medications. Next, you'll want some in-flight entertainment to while away the time. A juicy book and a phone filled with your favourite shows are some fantastic options. If you plan to take a short nap, a comfy neck pillow and a pair of earplugs will also come in handy. Finally, leave space for a toothbrush and some deodorant so you'll arrive at your destination feeling fresh and ready to go.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have a pocket knife lurking in one of the compartments of your carry-on luggage. Other banned items include explosive or flammable products, such as fuel and matches, and liquids and gels in containers with a volume of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Choose comfort over style. Prepare for temperature changes in the cabin by layering up, and wear easy-to-remove footwear like sneakers.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by lengthy periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin and stretch your legs or do some gentle exercises in your seat to improve your circulation.

How to get through airport security fast when flying to Troy?
It's easy --- be prepared. We've compiled some tips and tricks for a fuss-free trip through security. Watch out Troy, here you come:

  • Your travel documents and ID will need to be presented to airport security. Keep them someplace accessible so you don't have to dig around for them.
  • The X-ray machine comes next. Remove anything on you that is likely to set off the scanner's alarm. This includes items like earphones or headphones, as well as heavy jackets or coats. They'll need to be placed on the conveyor belt for screening.
  • For just a few moments, you'll have to unplug from technology. Your phone, tablet and any other electronic gadgets also need to go through the scanner.
  • Any gels or liquids, such as lip balm or cologne, that you want to take on board need to be in containers no greater than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-close bag.
  • Lightweight sneakers are a great footwear choice as you're less likely to be asked to remove them when passing through security. Boots and other heavy-style shoes are often subjected to additional screening.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, put them in your checked baggage. They won't be allowed on board.
