We've got the lowdown on how to make your journey as pain-free as possible. Follow our tips and you'll be hightailing it through the airport and having a blast in Billerica in no time flat. What to pack in your hand luggage:

• Flying can be a great experience if you pack the right gear. First things first, you'll need basic toiletries, such as a toothbrush and some deodorant, a clean pair of socks and a few magazines. Next, find a spot in your hand luggage for your mobile phone, a charger, any medications and perhaps a blow-up neck pillow too. Lastly, and most importantly, be sure to bring your passport, travel documents and some cash.

Do not pack the following items in your hand luggage:

• Leave all your full-sized bottles of shampoo and hair gel in your checked baggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated by security. Sharp objects, like your trusty pocket knife, and dangerous goods which are explosive or flammable, such as spray paint, flares and matches, are also restricted.

What to wear on a flight:

• Comfort should be your highest priority when deciding what to wear on your flight. Loose clothing is a sensible option, as are enclosed shoes like sneakers.
• Deep vein thrombosis (DVT), a blood clot condition caused by lengthy 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 improve your circulation.

As savvy travellers know, the secret is to be prepared before you reach the airport security gate. That way, you'll be hopping onto that plane to Billerica in no time at all. Follow these tips and get your trip off to a great start:

• Your passport and boarding pass will need to be presented to airport security personnel. Have them easily accessible so you don't hold up the queue.
• Time to strip down. Well kind of. Your belt, coat, keys and other items in your pocket, like your headphones, will be required to go through the X-ray machine. Make your life easier by removing them as your turn draws near.
• All your electronic devices, including your laptop and phone, are also required to be separately scanned.
• Travelling with your favourite hand cream? No problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, you can keep it with you in your carry-on luggage.
• Choosing your footwear wisely can save you several precious minutes. Hiking or heavy-style boots are often required to be removed and X-rayed separately. Lightweight sneakers are usually not.
• Airlines won't allow any sharp items or pocket knives in your hand luggage. If you must bring these kinds of items, pack them safely in your checked luggage.
