How to survive the flight to Cosmopolis?
We’ve pulled together all the info you need to make your flight a pleasant experience. Follow our tips and tricks and you’ll be breezing through the airport and having a blast in Cosmopolis in no time at all.What to pack in your hand luggage:

  • The secret to having an awesome flight experience is to pack ahead. First up, the essentials: passport, travel docs, cash and daily medications. Next, bring on board items that’ll help keep you busy, like some electronic devices or a juicy novel. You’ll also want to pack your chargers, a quality neck pillow and a pair of earplugs. Last but not least, be sure to chuck in toiletry items like a toothbrush, cleansing wipes and a fresh change of clothes.

Do not pack the following items in your hand luggage:

  • Make sure you don’t have sharp or pointed objects lurking in the bottom of your carry-on luggage. Other banned items include flammable or explosive goods, such as aerosol cans and fuel, and gels and liquids in containers with a volume of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The answer to a comfortable flight often lies in your clothing choices. Prepare for changes in temperature by layering up. That way you’ll stay nice and warm if the cabin gets too cold. Shoes like high heels and sandals are best left in your checked suitcase. Instead, go for flat, closed-toed footwear like sneakers. Your feet will thank you later.
  • The serious condition known as DVT (deep vein thrombosis) can pose a risk on long-haul flights. It results from blood clotting due to poor circulation and inactivity. Walking up and down the aisle and doing leg and foot exercises in your seat helps to prevent this from occurring. Wearing a good pair of compression socks can also help.

How to get through airport security fast when flying to Cosmopolis?
As seasoned travellers know, the secret is to be prepared before you arrive at the airport security gate. That way, you’ll be stepping onto that plane to Cosmopolis in the blink of an eye. Follow these helpful tips and get your holiday off to a fantastic start:

  • First things first. Your travel documents and passport will need to be presented to airport security personnel. Keep them within easy reach to avoid fumbling around for them.
  • Next up, both you and your carry-on luggage will be X-rayed. To speed things up, take off anything that might trigger the alarms. Items such as your jacket, belt and headphones will be required to go through the machine.
  • All your electronic gadgets, including your phone and laptop, must also be scanned.
  • Any liquids or gels, such as perfume or hand cream, that you want to bring on board must be no greater than 3.4 ounces (100 milliliters). They must also all fit inside a quart-size (one litre), zip-lock bag.
  • Choosing your footwear wisely can save you several valuable minutes. Hiking or heavy-style boots are often required to be removed and X-rayed separately. Slip-on sneakers usually aren’t.
  • Airlines won’t allow any sharp items or pocket knives in your hand luggage. If you need to bring these kinds of items, pack them in your checked luggage.
