  • Firstly, you'll need to take all applicable travel documents and your identification. How much is dependent on where you're departing from. When you book, you should always use the same name, gender and birth date as stated on your current ID.
  • A well-stocked carry-on bag is important for any lengthy flight. With several hours to kill, you'll probably long for something to keep you entertained while in the air. We recommend a good book or magazine, and something to snack on.
