How to survive the flight to Cosgrove?
Depending on where you’re coming from, your trip to Cosgrove could be no sweat at all or it could go on forever. Here are some handy tips that will help you start your next big adventure on a positive note.What to pack in your hand luggage:

  • The secret to having a stress-free flight experience is to pack ahead. Start with the essentials: passport, travel documents, bank cards and daily medications. Next, bring on board items that’ll help keep you busy, like your laptop or a thrilling novel. It’s also a wise idea to bring your chargers, a comfy neck pillow and a pair of earphones. Finally, don’t forget to squeeze in toiletry items like a toothbrush, deodorant and a clean T-shirt.

Do not pack the following items in your hand luggage:

  • Double-check that you don’t have sharp objects (like a knife or scissors) lurking in the bottom of your carry-on luggage. Other restricted items include flammable or explosive substances, such as fuel and fireworks, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The answer to a comfortable flight is often as simple as the clothes you wear. Prepare for changes in temperature by bringing layers. That way you’ll stay nice and warm if the cabin begins to cool down. Shoes like sandals and heels are best left in your suitcase. Even though they may be your favorites, opt for flat, closed-toed footwear like slip-ons. Your feet will thank you for it.
  • The serious condition called deep vein thrombosis (DVT) can pose a risk on long-haul flights. It results from blood clotting due to inactivity and poor circulation. Walking around the cabin and doing regular foot and leg exercises in your seat helps to prevent this from happening. Wearing a high-quality pair of compression tights or socks can also help.

How to get through airport security fast when flying to Cosgrove?
It’s easy — be prepared. We’ve put together some tips and tricks for a fuss-free trip through security. Look out Cosgrove, here you come:

  • Your passport and travel documents will need to be inspected by airport security. Keep them someplace accessible so you don’t have to dig around for them.
  • The X-ray machine comes next. Remove anything on you that is likely to beep. This includes items like earphones or headphones, as well as bulky coats or jackets. They’ll all need to go on the X-ray conveyor belt.
  • Electronic devices like phones and laptops will also have to go on a tray to be scanned. Don’t worry though, you’ll be back online soon enough.
  • Traveling with a new perfume or cologne? As long as the volume is no greater than 3.4 ounces (100 milliliters) and it’s stored in a clear zip-close bag, you can keep it with you in your carry-on baggage.
  • There’s a possibility that you’ll be required to remove your shoes for scanning, so wearing slip-on sneakers is always a clever idea.
  • Airlines won’t allow any sharp items or pocket knives in the cabin. If you need to bring these kinds of items, pack them safely in your checked luggage.
