What is Electronic ticket?

Electronic ticket (e-ticket)

The electronic record that proves a passenger has paid for air travel, stored in the airline's system rather than on paper. It carries a 13-digit ticket number whose first three digits identify the issuing airline, and it is linked to the PNR it was issued against.

Also called: ET, ticket number.

Why it matters

The PNR holds the booking; the e-ticket holds the payment and fare. Changes to an itinerary after ticketing usually require a reissue, not just an edit to the PNR.
