Do you have any tips for my flight to Sunnyside?
If you're poorly prepared, air travel can be testing. But don't hit the panic button just yet. Follow these tips and tricks and enjoy a hassle-free start to your getaway in Sunnyside. What to pack in your hand luggage:
  • It's easy — first, pack your passport, travel docs, cash and vital medications. Next, you'll need some entertainment to help pass the time. A juicy book and a tablet filled with your favourite movies are some terrific options. If you intend to catch a few z's, a neck pillow and some noise-cancelling headphones will also be useful. Finally, make room for a toothbrush and some deodorant to ensure you hop off the plane feeling fresh and raring to go.
Do not pack the following items in your hand luggage:
  • Squeeze all your full-sized bottles of shampoo and hairspray in your checked baggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Pointed or sharp objects, like your trusty pocket knife, and dangerous goods which are flammable or explosive, such as spray paint, flares and poisons, are also not allowed.
What to wear on a flight:
  • Comfort should be your number one priority when deciding what to wear on your flight. Loose clothing is a wise choice, as are flat, slip-on shoes.
  • You've probably heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of sitting. To lower your risk on board, drink plenty of water, consider wearing compression socks and move your legs and feet often.
How to get through airport security fast when flying to Sunnyside?
The answer is — be prepared. We've rounded up some tips and tricks for a fuss-free trip through security. Look out Sunnyside, here you come:
  • Security personnel first need to verify that you have a valid passport and travel documents before anything else. Have them in your hand, ready for inspection.
  • Your belt, jacket, keys and other contents of your pockets, like your earphones, will be required to go through the X-ray machine. Make the whole process easier by removing them as it gets closer to your turn.
  • All your electronic devices, including your tablet and phone, must also be scanned.
  • Can't travel without your favourite hand and nail cream? As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, it's OK to bring with you on board.
  • The right choice of footwear can save you a few precious minutes. Hiking or heavy-style boots are often required to be removed and separately scanned. Slip-on sneakers are usually not.
  • Airlines will not allow any sharp items or pocket knives in your carry-on baggage. If you must bring these kinds of items, pack them safely in your checked luggage.
