Cheap Flights to Rockville from HK$2,972

If you're not prepared, air travel can be tough. But there's no need to hit the panic button just yet. Follow these helpful hints for a stress-free start to your vacation in Rockville.What to pack in your hand luggage:

• Firstly, and most importantly, pack in your passport, important documents, bank cards and medications. Next, you'll want some in-flight entertainment to while away the hours. A thrilling book and a laptop filled with your favorite shows are some terrific options. If you plan to catch up on some sleep, a neck pillow and some noise-canceling headphones will also come in handy. Finally, leave space for a toothbrush and some facial wipes to ensure you arrive at your destination feeling fresh and raring to go.

Do not pack the following items in your hand luggage:

• Leave 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 milliliters) will be confiscated by authorities. Pointed or sharp objects, like your Swiss Army knife, and dangerous products which are explosive or flammable, such as flares, bleaching agents and fuels, are also restricted.

What to wear on a flight:

• The key to a comfortable flight can be as simple as your choice of clothing. Prepare for changes in temperature by bringing layers. This will keep you nice and warm if the cabin gets too cold. Shoes like stilettos, flip flops and lace-up boots are best left for other occasions. Instead, go for flat, closed-toed footwear like slip-ons. Your feet will thank you for it.
• A serious condition by the name of DVT (deep vein thrombosis) is a risk on long-haul flights. It results from blood clotting due to poor circulation and inactivity. Walking around the cabin and doing regular foot and leg exercises while seated helps to prevent this from occurring. Wearing a quality pair of compression tights or socks is also a wise idea.

The secret is to be prepared before you arrive at airport security. That way, you'll be boarding that plane to Rockville in the blink of an eye. Follow these helpful tips and get your vacation off to a great start:

• Airport security personnel first need to verify that you have a valid ID and boarding pass before anything else. Have them ready for inspection.
• The X-ray machine is up next. Empty your pockets and remove anything that is likely to beep. This includes items like earphones or headphones, as well as bulky coats or jackets. They'll need to be placed on the conveyor belt for screening.
• All your electronic devices, including your laptop and phone, are also required to be scanned separately.
• Remember to remove liquids and gels from your carry-on bag. They often need to be sent through the X-ray machine separately. Each item should be no larger than 3.4 ounces (100 milliliters) and everything must fit in a quart-size (one liter), clear zip-close bag.
• Lightweight sneakers are a good footwear choice as you're less likely to be required to remove them when passing through security. Hiking boots and other heavy-style shoes are often subjected to extra screening.
• Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked baggage. They won't be allowed in the cabin.
