A juicy book and a phone filled with your favourite shows are some terrific options. If you intend to catch more than just forty winks, a neck pillow and a pair of earplugs will also come in handy. Finally, leave some space for a toothbrush and some facial wipes so you'll touchdown looking and feeling fresh.
Do not pack the following items in your hand luggage:
  • While the list of restricted items differs between airlines, the general rule to follow is avoid carrying anything sharp, flammable or explosive. This includes screwdrivers, drills, fireworks and fuel. Sporting equipment like bows and arrows, and items that could injure passengers, such as firearms and ammunition, won't be allowed on board either.
What to wear on a flight:
  • Comfort should be your priority when deciding what to wear on your flight. Loose, breathable clothing is a wise choice, as are roomy, closed-toe shoes.
  • It's likely you've heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity. To lower your risk on board, stay hydrated, consider wearing compression socks or tights and do gentle foot and leg exercises in your seat.

As savvy travellers know, the secret is to be well organized before you reach security. That way, you'll be stepping onto that plane to Castelo do Piaui in a flash. Follow these helpful tips and get your vacation off to a flying start:
  • First things first. Your passport and travel documents will need to be shown to security personnel. Keep them at hand so you don't hold up the line.
  • Time to strip down. Well sort of. Your jacket, belt, keys and other items in your pocket, like coins, will need to go through the X-ray machine. Make your life easier by removing them as your turn draws near.
  • Electronic devices like phones and laptops will also have to go on a tray for inspection. Don't worry though, you'll be back online in no time.
  • Remove gels and liquids from your carry-on bag. They usually need to be sent through the X-ray machine separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a single quart-size (one litre), clear zip-lock bag.
  • There's a good chance you'll need to remove your shoes to be X-rayed, so wearing slip-on shoes is always a good idea.
  • Pocket knives and other sharp items are not allowed in the cabin. They'll be seized at security, so pack them safely away in your checked bags.
