Cheap Flights to Luján from HK$2,029

If you're poorly prepared, air travel can be challenging. But there's no need to panic. Follow these handy hints and enjoy a comfortable start to your holiday in Luján. What to pack in your hand luggage:

• First, put in your passport, official ID, bank cards and daily medications. Next, you'll need some extra in-flight entertainment to while away the hours. A thrilling novel and a laptop crammed with your favourite movies are some wonderful options. If you hope to catch forty winks, a neck pillow and a pair of noise-cancelling headphones will also come in handy. Finally, find room for a toothbrush and some cleansing wipes to ensure you arrive at your destination looking and feeling fresh.

Do not pack the following items in your hand luggage:

• Leave all your full-sized bottles of hair gel and hairspray in your checked luggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp or pointed objects, like a Swiss Army knife, and dangerous goods which are explosive or flammable, such as spray paint, flares and strong acids, are also banned.

What to wear on a flight:

• The aisles of a plane are no place for a fashion parade. Layer up with comfortable clothing and opt for shoes that are flat and easy to pull on and off.
• The result of sustained periods of immobility, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers during long-haul flights. Lower your risks by drinking water, keeping your legs and ankles moving and wearing compression tights or socks.

As savvy travellers know, the secret is to be prepared before you get to airport security. That way, you'll be stepping onto that plane to Luján in the blink of an eye. Follow these tips and get your trip off to a fantastic start:

• First things first. Your boarding pass and passport will need to be presented to security personnel. Keep them handy so you don't hold up the queue.
• Time to strip down. Well kind of. Your belt, coat, keys and other small items, like coins, will need to go through the X-ray machine. Make the whole process faster by removing them before your turn arrives.
• For just a few minutes, you'll have to unplug from technology. Your phone, laptop and any other electronic gadgets must also go through the scanner.
• Any liquids or gels, such as perfume or hairspray, that you want to take on board must be no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-close bag.
• Lightweight sneakers are a great footwear choice as you're less likely to be asked to remove them when going through security. Hiking boots and other heavy-style shoes are usually subjected to extra screening.
• Sharp or pointed items are prohibited in the cabin. They'll be confiscated at security, so put them in your checked suitcase.
