Electronic Tickets (eticket) are a convenient alternative to a paper ticket. With an Electronic Ticket, you only need to print a copy of your itinerary and keep it with you during your journey. You present it to the check in counter and it is accepted the same way as a paper ticket by the person checking you in for a flight.
If a printed itinerary is misplaced, a user, who has created a profile (registered) at the Air Niugini web site can go back to the site and retrieve a new one. Non-registered users must contact Air Niugini to have an itinerary emailed to them.
