Cheap Flights to Saint-Louis from HK$455

Depending on where you're coming from, your trip to Saint-Louis could be a breeze or it could drag on forever. We've compiled some handy hints that will help you start your next great adventure on the right foot. What to pack in your hand luggage:

• First, put in your passport, important documents, credit cards and vital medications. Next, you'll need some entertainment to help pass the time. A juicy book and a tablet filled with your favourite shows are good options. If you plan to take a short snooze, a neck pillow and some noise-cancelling headphones will also come in handy. Finally, squeeze in a toothbrush and some cleansing wipes so you'll arrive 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 rule of thumb is avoid carrying anything flammable, sharp or explosive. This includes things like knives, scissors, fireworks and fuel. Sports equipment like hockey sticks, and items that could injure passengers, such as swords and batons, can't come on board with you either.

What to wear on a flight:

• Go for comfort over style. Prepare for changes in cabin temperature by layering up, and wear flat, slightly roomy shoes like sneakers.
• Most of us have heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of sitting. To lower your risk on board, drink plenty of water, consider wearing compression socks or tights and keep your legs and feet moving.

It's easy — be prepared. We've rounded up some helpful hints for an easy trip through security. Look out Saint-Louis, here you come:

• Airport security personnel first need to make sure that you have a valid ID and boarding pass before you can proceed any further. Have them close by, ready for inspection.
• Next up, both you and your carry-on bag must be X-rayed. To make the process quick and painless, remove anything that is likely to set the alarm off. Items like your coat, belt and headphones will be required to go through the machine.
• All electronic devices, including your tablet and phone, are also required to be scanned.
• Travelling with your favourite hand cream? As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, it's fine to bring with you in your carry-on baggage.
• The right choice of footwear can save you valuable minutes. Boots are often required to be removed and X-rayed separately. Slip-on shoes are usually not.
• Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked baggage. They won't be allowed in the cabin.
