Cheap Flights to Grenoble from HK$549

If you're poorly prepared, air travel can be a real challenge. But there's no need to hit the panic button just yet. Follow these useful tips for a pleasant start to your holiday in Grenoble. What to pack in your hand luggage:

• The trick to having a pain-free travel experience is to pack in advance. So, let's start with the essentials: passport, boarding pass, credit cards and daily medications. Next, bring items that'll help pass the time, like some electronic gadgets or a thrilling book. You'll also want to pack your chargers, a neck pillow and a pair of noise-cancelling headphones. Finally, don't forget to chuck in toiletries like a toothbrush, cleansing wipes and a fresh set of clothes.

Do not pack the following items in your hand luggage:

• While the list of prohibited items can differ between airlines, the general rule of thumb is nothing sharp, flammable or explosive. This includes things like screwdrivers, drills, fuels and bleaching agents. Sports equipment like bows and arrows, and objects that could injure passengers, such as firearms and ammunition, aren't allowed in the cabin either.

What to wear on a flight:

• Your top priority is to be as comfortable as you can. Choose a pair of slip-on shoes, dress in loose, natural fibers and remember to take a jacket in case it gets cold in the cabin.
• Deep vein thrombosis (DVT) can pose a risk on long-distance flights. It results from blood clots forming due to inactivity and poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression socks.

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

• First things first. Your travel documents and ID will need to be shown to security personnel. Keep them at hand to avoid fumbling around for them.
• Your jacket, belt, keys and other items in your pocket, like coins, will need to go on a tray through the X-ray machine. Make your life easier by removing them before your turn arrives.
• For just a few moments, you'll have to unplug from the digital world. Your tablet, phone and any other electronic devices also need to go through the scanner.
• Any liquids or gels, such as perfume or hairspray, that you want to take on board need to be in containers no greater than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-lock bag.
• The right choice of footwear can save you valuable minutes. Boots and bulky shoes are often required to be removed and separately scanned. Lightweight sneakers usually aren't.
• Airlines won't allow any pocket knives or other sharp items in your carry-on baggage. If you need to bring these kinds of items, pack them in your checked luggage.
