So, let's start with the essentials: passport, travel documents, cash and vital medications. Next, bring on board items that'll help while away those hours, like some electronic devices or a thrilling book. It's also a wise idea to pack your chargers, a comfy neck pillow and a pair of earplugs. Last but not least, be sure to toss in toiletries like a toothbrush, lip balm and a spare change of clothes. > > > Do not pack the following items in your hand luggage: > > > - While the list of prohibited items differs between air carriers, the general rule to follow is nothing flammable, sharp or explosive. This includes screwdrivers, drills, fuel and fireworks. Sports equipment like golf clubs, and objects that could injure passengers, such as pepper spray and guns, aren't allowed in the cabin either. > > > What to wear on a flight: > > > - Comfort should be your highest priority when choosing what to wear on your flight. Loose clothing is a smart option, as are flat, slightly roomy shoes. > - 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 improve your circulation. ### How to get through airport security fast when flying to Boston? > - Security personnel first need to see that you have a valid ID and boarding pass before anything else. Have them ready to show. > - Time to strip down. Well kind of. Your jacket, belt, keys and other items in your pocket, like coins, will need to go through the X-ray machine. Make your life easier by removing them as it gets closer to your turn. > - Your electronic gadgets like laptops and phones will also need to go on a tray to be scanned. No need to worry though, you'll be back online before you know it. > - Travelling with a new cologne or perfume? Not a problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-close bag, you can keep it with you in your carry-on baggage. > - Slip-on shoes are a sensible footwear choice as you're less likely to have to remove them when going through security. Hiking boots and heavier-style shoes are usually subjected to extra screening. > - Sharp items are not allowed on board. They'll be confiscated at security, so pack them safely away in your checked bags. __Flights to Boston information__ | Destination airport | Louisville Intl. | | ----------------------------- | ---------------- | | Destination airport IATA code | SDF | | Destination city name | Louisville | | Roundtrip price | CA $377 | ## Trending flights to Boston Prices were available within the past 7 days and start at CA $231 for one-way flights and CA $377 for round trip, for the period specified.
