Next, you'll want some extra in-flight entertainment to while away the time. A juicy novel and a phone crammed with your favourite shows are some great options. If you plan to take a quick nap, a comfy neck pillow and a pair of noise-cancelling headphones will also come in handy. Finally, find room for a toothbrush and some deodorant to ensure you arrive at your destination feeling fresh and raring to go. > > > Do not pack the following items in your hand luggage: > > > - While the list of banned items differs between airlines, the general guide to follow is avoid carrying anything sharp, flammable or explosive. This includes things like screwdrivers, pocket knives, fuel and fireworks. Sports equipment like hockey sticks, and items that could harm other people, such as firearms and ammunition, are also banned from the cabin. > > > What to wear on a flight: > > > - The aisles of an aircraft aren't the place for a fashion parade. Layer up with comfy clothing and choose shoes that are flat and easy to slip on and off. > - Caused by sustained periods of immobility, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers during long-haul flights. Lower your risks by staying hydrated, keeping your lower limbs moving and wearing compression socks to help improve your circulation. ### How to get through airport security fast when flying to Swansea? > - First things first. Your ID and travel documents will need to be shown to airport security. Keep them someplace accessible so you don't hold up the line. > - Next up, both you and your carry-on luggage will be X-rayed. To make the process quick and painless, remove anything that might set the alarms off. Items such as your belt, jacket and earphones need to go through the machine. > - For just a few moments, you'll have to unplug from technology. Your phone, laptop and any other electronic gadgets will also need to be sent through the scanner. > - 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 clear zip-lock bag, you can keep it with you in your carry-on luggage. > - Lightweight sneakers are a clever footwear choice as you're less likely to be required to remove them when passing through security. Hiking boots and other heavy shoes are often subjected to extra screening. > - Airlines won't allow any sharp or pointed objects to come on board with you. If you must bring these kinds of items, pack them safely in your checked baggage. __Flights to Swansea information__ | Destination airport | Lambert-St. Louis Intl. | | ----------------------------- | ----------------------- | | Destination airport IATA code | STL | | Destination city name | St. Louis | | Roundtrip price | CA $215 | ## Trending flights to Swansea Prices were available within the past 7 days and start at CA $108 for one-way flights and CA $215 for round trip, for the period specified.
