From onboard entertainment to travel necessities like a pillow, there are several things a regular flyer always takes with them. To ensure you're ready for your adventure, have a look at this useful list:

  • Travel documentation such as visas and identification are essential. To avoid any unnecessary delays at check-in, ensure that your booking is made with the same name, gender and birth date as your current ID.
