Do you have any tips for my flight to St. Louis?
Wherever you're jetting in from, flying can be a pleasant experience if you've prepared well enough. We've compiled a list of essential travel tips that will help get your St. Louis escape started on the right note. What to pack in your hand luggage:

  • Air travel can be a great experience if you've got all the right stuff. Firstly, you'll need basic toiletry items, such as lip balm and hand cream, a clean pair of socks and a magazine or two. Next, find a spot in your carry-on bag for your phone, tablet and chargers, any vital medications and perhaps a comfy neck pillow too. Lastly, remember to bring your passport, travel docs and some cash.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of hair gel and hairspray in your checked baggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Sharp objects, like your treasured Swiss Army knife, and dangerous products which are flammable or explosive, such as aerosol cans, spray paint and fireworks, are also banned.

What to wear on a flight:

  • The aisles of a plane aren't the place for a fashion parade. Wear layers and pick shoes that are roomy, flat and easy to slip on and off.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin and stretch your legs or do some gentle exercises in your seat to promote better circulation.

How to get through airport security fast when flying to St. Louis?
As savvy travellers know, the secret is to be prepared before you get to the security gate. That way, you'll be stepping onto that plane to St. Louis in the blink of an eye. Follow these tips and get your trip off to a flying start:

  • Airport security personnel first need to make sure that you have a valid ID and matching travel documents before anything else. Have them ready for inspection.
  • The X-ray machine comes next. Empty your pockets and remove anything metal that is likely to set off the scanner's alarm. This includes items like headphones or earphones, as well as bulky coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • Your electronic gadgets like phones and laptops will also have to go on a tray to be scanned. Don't worry, you'll be back online before you know it.
  • Remove liquids and gels from your carry-on bag. They often need to be sent through the X-ray machine separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a quart-size (one litre), clear zip-lock bag.
  • There's a possibility that you'll be required to remove your shoes for scanning, so wearing slip-on shoes is always a good idea.
  • Sharp or pointed items can't be taken on board. They'll be seized at security, so pack them in your checked suitcase.
