We've pulled together all the info you need to make your flight a stress-free experience. Follow our tips and tricks and you'll be zooming through airport security and discovering O'Fallon in next to no time. What to pack in your hand luggage:

• It's simple — first, pack in your passport, travel documents, credit cards and vital medications. Next, you'll need some in-flight entertainment to while away the hours. A thrilling novel and a laptop crammed with your favourite shows are good options. If you plan to take a quick snooze, a comfy neck pillow and a pair of earplugs will also be useful. Finally, leave some space for a few toiletry items so you'll step off the plane looking and feeling fresh.

Do not pack the following items in your hand luggage:

• Check carefully that you don't have a sharp object hiding in the bottom of your hand luggage. Other banned items include flammable or explosive goods, such as aerosol cans and bleach, and liquids and gels in containers larger than 3.4 ounces (100 millilitres).

What to wear on a flight:

• Your main aim is to be as comfortable as possible. Choose slip-on footwear, dress in loose, breathable clothing and remember to take a sweater in case it gets cold in the cabin.
• The result of sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers during long flights. Reduce the risks by staying hydrated, keeping your legs moving and wearing compression tights or socks.

The trick is to be well organised before you arrive at security. That way, you'll be hopping onto that plane to O'Fallon in no time at all. Follow these helpful tips and get your holiday off to a spectacular start:

• First things first. Your travel ID and boarding pass will need to be inspected by security personnel. Have them close by so you don't hold up the line.
• The X-ray machine is up next. Remove anything on you that is likely to beep. This includes things like headphones or earphones, as well as your coat or jacket. They'll need to be placed on the conveyor belt for screening.
• Electronic devices like phones and laptops will also need to go on a tray for inspection. No need to worry though, you'll be back online before you know it.
• Any gels or liquids, such as perfume or hairspray, that you want to bring on board must be no larger than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-lock bag.
• It's also likely that you'll need to remove your shoes to be X-rayed, so wearing slip-on sneakers is always a good idea.
• Airlines will not allow any sharp items or pocket knives to come on board with you. If you need to bring these kinds of items, put them in your checked luggage.
