Electronic Ticket
A digital record of a flight booking that replaces the traditional paper ticket and is stored electronically in the airline's reservation system.
An electronic ticket is the standard form of airline ticketing — a digital record stored in the airline's departure control system that contains all of the passenger's booking details, fare conditions, and travel entitlements. The traveler receives a booking reference rather than a physical document, and the ticket is retrieved at check-in by presenting the reference number alongside valid identification. Electronic ticketing eliminated the need to carry and protect paper tickets and enabled modern online booking processes.
Why it matters
Electronic ticketing underpins the entire modern travel booking infrastructure. For corporate travel, it enables seamless integration between booking tools, GDS systems, airline check-in systems, and expense platforms. Changes, cancellations, and upgrades are all managed against the electronic record, with updates flowing through the distribution chain automatically. Travellers no longer risk missing a flight because they lost a physical document — but they do need to carry government-issued ID to prove identity at check-in.
How it works in practice
When a booking is confirmed, the airline issues an e-ticket and assigns a unique 13-digit ticket number that the traveler can use as a reference at every stage of the journey. The booking reference — a shorter alphanumeric code — is displayed on the booking confirmation and itinerary. At check-in, the airline retrieves the e-ticket from its database using the reference number and identity verification. Boarding passes are then issued physically at the airport or as a mobile barcode.
The takeaway
Save the booking confirmation and ticket number for every trip. In the event of a system disruption, a dispute, or a missed flight, the ticket number is the primary reference for the airline to retrieve the booking, process a change, or issue a refund. TMCs and booking tools that store this information in a centralized itinerary management system give travellers access to their booking details even when they lose the original confirmation email.
