Firstly, you'll want a few basic toiletries, such as a toothbrush and lip balm, a fresh change of clothes and a good book. Secondly, find room in your carry-on bag for your phone, tablet and chargers, your important medications and perhaps a comfy neck pillow as well. Lastly, don't forget to bring your passport, travel docs and some money. > > > Do not pack the following items in your hand luggage: > > > - Check carefully that you don't have a Swiss Army knife lurking in the bottom of your carry-on luggage. Other restricted items include explosive or flammable goods, such as bleach and fuel, 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 priority when deciding what to wear on board. Loose clothing is a wise option, as are flat, slightly roomy shoes. > - It's likely you've heard about deep vein thrombosis (DVT), a blood clotting condition caused by long periods of sitting. To minimize your risk on board, drink lots of water, consider wearing compression tights or socks and keep your feet and legs moving. ### How to get through airport security fast when flying to Warrenton? > - Have your ID and boarding pass handy. They'll be the first things you'll be asked for by security. > - Time to strip down. Well sort of. Your belt, coat, keys and other contents of your pockets, like your headphones, will need to go on a tray through the X-ray machine. Make the whole process faster by removing them before your turn arrives. > - Electronic devices like phones and laptops will also need to go on a tray to be scanned. Don't worry though, you'll be back online before you know it. > - Can't travel without your favourite hand cream? Not a problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, it's fine to bring with you in your carry-on. > - There's a chance you'll need to remove your shoes to be X-rayed, so wearing lightweight sneakers is always a clever idea. > - Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, put them in your checked luggage. They won't be allowed on board. __Flights to Warrenton information__ | Destination airport | Lambert-St. Louis Intl. | | ----------------------------- | ----------------------- | | Destination airport IATA code | STL | | Destination city name | St. Louis | | Roundtrip price | CA $216 | ## Trending flights to Warrenton Prices were available within the past 7 days and start at CA $108 for one-way flights and CA $216 for round trip, for the period specified.
