Cheap Flights to Baltimore from HK$4,646

If you're poorly prepared, airports and flying can be daunting. But don't hit the panic button just yet. Follow these useful tips for a pain-free start to your time in Baltimore. What to pack in your hand luggage:

• The secret to having a worry-free flight experience is to pack in advance. So, let's start with the basics: passport, official ID, cash and daily medications. Next, bring on board items that'll help keep you busy, like your laptop or a good book. It's also wise to pack your chargers, a quality neck pillow and a pair of earplugs. And of course, don't forget to chuck in toiletries like a toothbrush, deodorant and a fresh change of clothes.

Do not pack the following items in your hand luggage:

• While the list of prohibited items differs between airlines, the general rule to follow is nothing flammable, sharp or explosive. This includes screwdrivers, drills, fuels and bleaching agents. Sporting equipment like baseball bats, and items that could harm passengers, such as swords and batons, are also banned from the cabin.

What to wear on a flight:

• Your priority is to feel as comfortable as you can. Go for slip-on footwear, dress in loose, natural-fibre clothing and remember to bring a pullover in case you get chilly in the cabin.
• The result of sustained periods of immobility, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers during long-distance flights. Lower your risks by staying hydrated, keeping your legs and ankles moving and wearing compression socks to help your circulation.

Being prepared before you get to the airport will make your trip to Baltimore quick and painless. Here are some handy tips and tricks for a speedy journey past security:

• Airport security personnel first need to make sure that you have a valid passport and matching boarding pass before you're allowed to proceed any further. Have them close by, ready for inspection.
• The X-ray machine is up next. Remove anything on you that is likely to set off the scanner's alarm. This includes things like headphones or earphones, as well as bulky coats or jackets. They'll need to be placed on the conveyor belt for screening.
• Your electronic gadgets like phones and laptops will also have to go on a tray for inspection. Don't worry though, you'll be back online before you know it.
• Any liquids or gels, such as shampoo or hairspray, that you want to bring on board must be no larger than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-close bag.
• There's a good chance you'll be required to remove your shoes for scanning, so wearing lightweight sneakers is always a smart idea.
• Airlines won't allow any sharp objects in the cabin. If you need to bring these kinds of items, put them in your checked luggage.
