### How far is STL from central Troy? ### What airport is best to fly into Troy? ### How many airlines fly to Troy? ### Which airlines fly to Troy? ### How many nonstop flights are there to Troy? ### Where are the most popular flights to Troy departing from? ### How long is the flight to Troy Airport? ### How to book the cheapest flight to Troy? ### Do you have any tips for my flight to Troy? > - Air travel can be a stress-free experience if you pack the right gear. Firstly, you'll need toiletry items, such as lip balm and hand cream, a fresh change of clothes and a few magazines. Secondly, find a spot in your carry-on bag for your laptop, a charger, any daily medications and maybe a comfy neck pillow too. Lastly, be sure to take your passport, travel docs and your credit cards. > > > 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 box cutters, razor blades, fuel and fireworks. Sporting equipment like golf clubs, and objects that could injure passengers, such as swords and guns, are also banned from the cabin. > > > What to wear on a flight: > > > - Choose comfort over style. Prepare for changes in cabin temperature by dressing in layers, and wear flat, enclosed shoes like slip-ons. > - Deep vein thrombosis (DVT), a blood clotting condition caused by lengthy periods of 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 promote better circulation. ### How to get through airport security fast when flying to Troy? > - First things first. Your travel documents and passport will need to be presented to airport security personnel. Have them close by so you don't hold up the queue. > - The X-ray machine comes next. Remove anything on you that is likely to set off the alarm. This includes items like headphones or earphones, as well as heavy coats or jackets. They'll all need to go on the X-ray conveyor belt. > - All electronic devices, including your phone and laptop, are also required to be scanned separately. > - Any gels or liquids, such as hair oil or hand cream, that you want to bring on board need to be in containers no larger than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), zip-lock bag. > - Lightweight sneakers are a clever footwear choice as you're less likely to have to remove them when passing through security. Big boots and other heavy-style shoes are usually subjected to additional screening. > - Airlines won't allow any sharp items or pocket knives to come on board with you. If you must bring these kinds of items, check them in. ## Book with confidence # Expedia flights to Troy Searching for cheap flights to Troy?
