Do you have any tips for my flight to Cosby?
If you're not prepared, air travel can be a real challenge. But there's no need to hit the panic button just yet. Follow these useful tips and enjoy a trouble-free start to your time in Cosby. What to pack in your hand luggage:

  • Air travel can be a comfortable experience if you pack the right stuff. Firstly, you'll want a few basic toiletry items, such as a toothbrush and lip balm, a clean pair of socks and a magazine or two. Next, find room in your bag for your electronic devices, chargers, any vital medications and maybe a neck pillow too. Lastly, remember to bring your passport, travel docs and some cash.

Do not pack the following items in your hand luggage:

  • While the list of banned items differs between airlines, the general guide to follow is nothing sharp, flammable or explosive. This includes box cutters, razor blades, fireworks and fuel. Sporting equipment like golf clubs, and items that could harm other people, such as firearms and swords, aren't allowed in the cabin either.

What to wear on a flight:

  • The aisles of a plane aren't the place for a fashion parade. Layer your clothing and go for shoes that are roomy, flat and easy to remove.
  • The result of lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect some passengers on long-haul flights. Reduce the risks by staying hydrated, keeping your legs and ankles moving and wearing compression socks or tights.

How to get through airport security fast when flying to Cosby?
As seasoned travellers know, the secret is to be well prepared before you get to airport security. That way, you'll be hopping onto that plane to Cosby in no time flat. Follow these tips and get your trip off to a terrific start:

  • Have your travel documents and ID easily accessible. They'll be the first things you'll be asked to present to security.
  • The X-ray machine is up next. Remove anything metal on you that is likely to set off the alarm. This includes items like headphones or earphones, as well as heavy coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • Electronic devices like laptops and phones will also have to go on a tray for inspection. Don't worry, you'll be back online soon enough.
  • Any liquids or gels, such as shampoo or hand cream, that you want to take on board must be no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), zip-lock bag.
  • Choosing your footwear wisely can save you several valuable minutes. Boots and heavy shoes are often required to be removed and separately scanned. Slip-on shoes usually aren't.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, put them in your checked suitcase. They won't be allowed on board and will be confiscated.
