Cheap Flights to Grinnell from HK$1,759

We've got the lowdown on how to make your flight as enjoyable as possible. Follow our insider tips and you'll be cruising through airport security and enjoying Grinnell in no time at all. What to pack in your hand luggage:

• The secret to having an awesome flight experience is to pack in advance. So, let's start with the essentials: passport, travel docs, credit cards and daily medications. Next, take on board items that'll help keep you occupied, like your laptop or a good read. It's also wise to bring your chargers, a comfy neck pillow and a pair of noise-cancelling headphones. Finally, be sure to pop in toiletries like a toothbrush, deodorant and a clean T-shirt.

Do not pack the following items in your hand luggage:

• While the list of restricted items differs between air carriers, the general rule to follow is avoid carrying anything flammable, sharp or explosive. This includes box cutters, razor blades, aerosol cans and flares. Sporting equipment like ice skates, and items that could harm other people, such as guns and swords, can't come on board with you either.

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 pick shoes that are flat, enclosed and easy to remove.
• Deep vein thrombosis (DVT), a blood clotting condition caused by lengthy periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin and stretch your legs or do some gentle exercises in your seat to improve your circulation.

As seasoned travellers know, the secret is to be well organised before you get to airport security. That way, you'll be stepping onto that plane to Grinnell in no time flat. Follow these helpful tips and get your holiday off to a great start:

• Airport security personnel first need to check that you have a valid passport and boarding pass before you can proceed any further. Have them in your hand, ready for inspection.
• Next up, both you and your carry-on bag must be X-rayed. To speed things up, remove anything that might set the alarms off. Items such as your coat, belt and headphones need to go through the machine.
• All your electronic gadgets, including your laptop and phone, will also need to be scanned.
• Any gels or liquids, such as perfume or hairspray, that you want to bring on board need to be in containers no larger than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-lock bag.
• Lightweight sneakers are a great footwear choice as you're less likely to be required to remove them when passing through security. Hiking boots and heavier-style shoes are usually subjected to extra screening.
• Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, pack them in your checked baggage. They won't be allowed in the cabin.
