First of all you'll need basic toiletry items, such as lip balm and hand cream, a spare set of clothes and a few magazines. Next, make room in your bag for your mobile phone, a charger, medications and perhaps a blow-up neck pillow as well. Lastly, be sure to take your passport, travel documents and some cash. > > > Do not pack the following items in your hand luggage: > > > - Check carefully that you don't have a pocket knife hiding in one of the compartments of your hand luggage. Other prohibited items include flammable or explosive products, such as aerosol cans and bleach, and liquids and gels in containers with a volume of more than 3.4 ounces (100 millilitres). > > > What to wear on a flight: > > > - Comfort should be your highest priority when choosing what to wear on board. Loose, breathable clothing is a sensible option, as are flat, slightly roomy shoes. > - Deep vein thrombosis (DVT) is a potential risk on long-haul flights. It's the result of blood clots forming due to inactivity and poor circulation, 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 Ballwin? > - First things first. Your boarding pass and travel ID will need to be presented to security personnel. Have them close by so you don't hold up the line. > - After that, both you and your carry-on luggage will be X-rayed. To speed things up, take off anything that might set the alarms off.

Your tablet, phone and any other electronic devices also need to be sent through the scanner. > - Travelling with a new cologne or perfume? No problem. As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, it's fine to bring with you in your carry-on. > - It's also possible you'll need to take your shoes off to be X-rayed, so wearing lightweight sneakers is always a smart idea. > - Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked baggage. They won't be allowed on board. __Flights to Ballwin information__ | Destination airport | Lambert-St. Louis Intl. | | ----------------------------- | ----------------------- | | Destination airport IATA code | STL | | Destination city name | St. Louis | | Roundtrip price | CA $215 | ## Trending flights to Ballwin 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.
