We've pulled together all the info you need to make your flight an enjoyable experience. Follow our tips and tricks and you'll be breezing through the airport and exploring Louisville in no time at all. What to pack in your hand luggage:

• The trick to having a great flight experience is to pack in advance. So, let's start with the basics: passport, travel documents, cash and any vital medications. Next, take on board items that'll help pass the time, like your laptop or a good read. You'll also want to bring your chargers, a neck pillow and a pair of noise-cancelling headphones. Finally, be sure to chuck in toiletry items like a toothbrush, deodorant and a fresh change of clothes.

Do not pack the following items in your hand luggage:

• Squeeze all your full-sized bottles of shampoo and conditioner in your checked luggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) won't be allowed on. Sharp objects, like your treasured pocket knife, and products which are explosive or flammable, such as aerosols and poisons, are also banned.

What to wear on a flight:

• Your main priority is to feel as comfortable as possible. Opt for a pair of slip-on shoes, dress in loose, natural fibers and remember to take a sweater in case it gets cold in the cabin.
• Deep vein thrombosis (DVT), a blood clot condition caused by prolonged inactivity, can be a risk on long-haul flights. Try to walk around the cabin and stretch your legs or do some simple exercises in your seat to promote better circulation.

The simple answer is — be prepared. We've compiled some tips and tricks for a hassle-free trip through security. Look out Louisville, here you come:

• Be sure to keep your passport and travel documents easily accessible. They're the first items you'll be asked to show at security.
• The X-ray machine comes next. Remove anything metal 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.
• All your electronic devices, including your tablet and phone, are also required to be separately scanned.
• Remove all liquids and gels from your carry-on bag. They often need to be sent through the X-ray separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-close bag.
• There's a possibility that you'll be asked to remove your shoes to be X-rayed, so wearing slip-on sneakers is always a smart idea.
• Pocket knives and other sharp items are prohibited in the cabin. They'll be confiscated at security, so pack them safely away in your checked luggage.
