Cheap Flights to Sofia from HK$271

If you're not prepared, air travel can be tough. But there's no need to panic. Follow these handy hints for a hassle-free start to your getaway in Sofia. What to pack in your hand luggage:

• A plane ride can be a pleasure if you carry the right things. Firstly, you'll want a few basic toiletry items, such as a toothbrush and lip balm, a spare pair of socks and a good book. Secondly, find room in your hand luggage for your electronic gadgets, chargers, any vital medications and maybe a cosy neck pillow as well. Last, but definitely not least, remember to take your passport, travel papers and some cash.

Do not pack the following items in your hand luggage:

• Put all your full-sized bottles of shampoo and hair gel in your checked luggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp objects, like your pocket 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 an airplane aren't the place for a fashion parade. Layer up with comfy clothing and choose shoes that are flat and easy to slip on and off.
• It's likely you've heard about deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of sitting. To minimize your risk on board, drink lots of water, consider wearing compression socks or tights and do gentle foot and leg exercises in your seat.

A little pre-planning before your flight will make your getaway to Sofia a piece of cake. We've rounded up some handy tips for a swift journey past security:

• Keep your travel documents and passport within easy reach. They're the first items you'll be asked for by security.
• Your belt, coat, keys and other small items, like your earphones, will need to go through the X-ray machine. Make the whole process easier by removing them before your turn arrives.
• Your electronic gadgets like phones and laptops will also need to go on a tray to be scanned. Don't worry, you'll be back online soon enough.
• Can't travel without your favourite cologne? No problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, it's fine to bring with you on board.
• The right choice of footwear can save you valuable minutes. Boots and heavy shoes are often required to be removed and separately scanned. Slip-on sneakers usually aren't.
• Pocket knives and other sharp items are prohibited in the cabin. They'll be seized at security, so pack them safely away in your checked suitcase.
