Airline & Travel Technology Glossary

The definitive dictionary of airline reservation systems, GDS cryptic syntax, PNR protocols, IATA NDC data standards, and distribution architecture.

PNR airline distribution

Passenger Name Record

A 6-character alphanumeric record in a Computer Reservation System (CRS) or Global Distribution System (GDS) that contains the complete itinerary, passenger details, contact information, and ticketing status for a traveler or group.

Real-World: When booking a flight from London to Tokyo on Sabre or Amadeus, a unique booking reference like 'W9K7ZQ' is generated. The passenger uses this PNR on the airline website to verify their reservation.
  • Mandatory components include Name, Itinerary, Contact, Received-From, and Ticketing Time Limit (PRINT rule).
  • A PNR holds live airline seat inventory before and after financial ticket issuance.
  • Accepted worldwide by embassies and consulates as proof of flight itinerary for visa processing.
GDS travel technology

Global Distribution System

A computerized network system operated by companies such as Sabre, Amadeus, and Travelport that enables automated transactions between travel service providers (airlines, hotels, car rental) and travel agencies.

Real-World: Online travel agencies and B2B aggregators connect to Sabre Web Services or Amadeus GDS via REST/SOAP APIs to search live flight availability, reserve seats, and issue verifiable PNRs.
  • Connects over 400+ scheduled commercial airlines globally.
  • Processes multi-airline interline connections and global fare quotes in milliseconds.
  • Provides real-time inventory synchronization to prevent double-booking.
Sabre gds systems

Sabre Global Distribution System

One of the world's largest travel technology and GDS platforms, originally developed by American Airlines and IBM, powering flight reservations, airline operations, and agency distribution.

Real-World: Dummy Ticket Factory connects directly to Sabre APIs to query live flight schedules, create verifiable PNRs, and manage reservation queues.
  • Used by hundreds of thousands of travel agents and corporate booking engines worldwide.
  • Provides industry-standard Bargain Finder Max (BFM) low-fare search engines.
  • Issues Sabre Record Locators that are recognized by all major global carriers.
Amadeus gds systems

Amadeus IT Group GDS

A European-headquartered global distribution system and travel technology company powering reservation, inventory, and departure control systems for airlines worldwide (Altéa suite).

Real-World: Lufthansa, Air France, and British Airways host their native reservations on Amadeus Altéa, allowing immediate PNR synchronization across agent portals.
  • Dominant GDS in Europe, Asia, and the Middle East.
  • Provides robust Master Pricer search algorithms and native NDC XML/JSON endpoints.
  • Synchronizes airline host inventory with external OTA reservation systems.
NDC airline distribution

New Distribution Capability

An XML-based data transmission standard launched by the International Air Transport Association (IATA) enabling airlines to distribute rich content, personalized offers, and dynamic ancillaries directly to travel agencies and OTAs.

Real-World: A traveler booking via an NDC-enabled OTA can select seat pitch, extra baggage, and Wi-Fi bundles directly from the airline rather than basic EDIFACT fare codes.
  • Created by IATA under Resolution 787 to modernize legacy EDIFACT messaging.
  • Allows airlines to provide personalized corporate and dynamic fare pricing.
  • Supported across both direct airline APIs and modern GDS aggregators.
E-Ticket ticketing

Electronic Ticket (ETKT)

A 13-digit digital flight document stored in an airline reservation database that represents a paid contract of carriage between the passenger and airline, superseding traditional paper tickets.

Real-World: An Emirates e-ticket starting with airline accounting code 176 (e.g. 176-2489102834) is issued only after credit card or BSP settlement is confirmed.
  • The first 3 digits represent the IATA airline accounting prefix.
  • Differs from a PNR: A PNR is the reservation container; the e-ticket is the financial coupon.
  • Linked directly to the flight segments inside the passenger's PNR.
EMD ticketing

Electronic Miscellaneous Document

The IATA standard electronic document used to collect and fulfill airline ancillary services, penalty fees, excess baggage, lounge access, and seat selection charges.

Real-World: When an agent adds an extra 23kg checked bag to a reservation, an EMD-A (Associated) coupon is generated and tied to the primary e-ticket coupon.
  • EMD-A is associated directly with a flight ticket flight coupon.
  • EMD-S is a standalone voucher used for non-flight services like lounge entry or ground transport.
  • Standardized by IATA Resolution 725f across GDS and travel agencies.
TTL airline distribution

Ticketing Time Limit

The exact deadline set by an airline revenue management system by which a held reservation (PNR) must be ticketed, otherwise the reserved seat inventory is automatically cancelled by the airline.

Real-World: An airline PNR may display 'TKT/TIME LIMIT BY 14OCT 23:59'. If payment or ticket issue does not occur by that timestamp, the airline robot sweeps and releases the seats.
  • Enforced by automated airline inventory robots (e.g., Sabre Robot / Amadeus Queue Sweeper).
  • Allows visa applicants and travel agents to hold confirmed seats without immediate non-refundable payment.
  • Varies based on flight departure date, fare class, and airline booking rules.
Dummy Ticket travel documentation

Verifiable Flight Itinerary / Flight Reservation

A genuine, held airline reservation containing a valid PNR generated through a licensed GDS system, used primarily as proof of intended travel for visa applications, embassy interviews, and immigration onward travel clearance without purchasing expensive non-refundable airfare upfront.

Real-World: A traveler applying for a Schengen visa at the French Embassy submits an official flight reservation PDF with a live PNR. The visa officer checks the PNR on the airline website to verify the applicant's travel route.
  • Features real flight numbers, departure/arrival airports, dates, and active passenger name record.
  • Verifiable directly on the operating airline's 'Manage Booking' portal.
  • Specifically requested by Schengen embassies (VFS, BLS, TLScontact) to prevent applicants from losing money on non-refundable tickets prior to visa approval.
Flight Reservation for Visa travel documentation

Embassy Flight Itinerary for Visa Application

A formal itinerary document displaying planned flight schedules, airline route, traveler names, and active booking code (PNR) submitted to embassies and consulates as mandatory proof of travel intent.

Real-World: Consulates worldwide explicitly recommend NOT purchasing confirmed, non-refundable flight tickets until visa approval. A verifiable flight reservation satisfies the requirement with zero financial risk.
  • Required for Schengen (90-day short stay), UK Standard Visitor, US B1/B2, and Canadian TRV visas.
  • Must match the exact dates of the travel health insurance and hotel accommodation vouchers.
  • Validates entry and exit dates to ensure the applicant intends to leave the destination before visa expiry.
Proof of Onward Travel travel documentation

Return / Onward Flight Ticket Requirement

A mandatory immigration and airline boarding regulation requiring international travelers entering on tourist or visa-exempt status to demonstrate a booked flight departing the country within the authorized stay period.

Real-World: A digital nomad flying one-way into Thailand, Costa Rica, or Indonesia is asked by airline check-in agents to present an onward ticket out of the country before receiving a boarding pass.
  • Airlines enforce this strictly because immigration authorities fine airlines for transporting passengers denied entry (Timatic rules).
  • Can be fulfilled with an official verifiable onward flight reservation rather than a fully paid ticket.
  • Protects travelers from being stranded or forced to purchase overpriced last-minute airport tickets.
OTA travel technology

Online Travel Agency

A web-based marketplace that aggregates, compares, and books travel products including flights, hotels, car rentals, and insurance directly for consumers and B2B agents via GDS and NDC integrations.

Real-World: Dummy Ticket Factory functions as a specialized OTA platform (Project OTA) providing flight itinerary generation, hotel vouchers, and white-label agency tools.
  • Connects to multiple GDS providers, airline NDC endpoints, and hotel bed banks.
  • Automates booking confirmation, PDF itinerary generation, and payment gateway settlement.
  • Supports multi-currency conversion and international language localization.
White-Label Travel Portal travel technology

B2B Rebranded Travel Booking Platform

A turnkey software solution allowing travel agencies, visa consultants, and affiliate partners to operate an online travel booking engine under their own brand, logo, and domain while utilizing an underlying OTA infrastructure.

Real-World: A visa agency in Dubai uses Dummy Ticket Factory's white-label portal to issue flight itineraries directly to clients with their agency logo and custom margin markup.
  • Custom domain mapping (CNAME) and agency branding on all generated PDF tickets.
  • Automated wholesale pricing with custom agency profit markups.
  • Real-time wallet and instant PDF generation with zero technical infrastructure required.
Married Segments airline distribution

Married Segment Control (MSC)

An airline revenue management logic that binds two or more connecting flight segments together as a single origin-destination package, preventing agents from breaking the connection or cancelling single legs to bypass pricing.

Real-World: A flight from New York to Paris connecting through London may have available cheap seats that are strictly unavailable if booking London to Paris as a standalone leg.
  • Enforced automatically across Sabre, Amadeus, and Travelport GDS.
  • Violating married segment rules can trigger automated airline debit memos (ADMs).
  • Ensures accurate through-fare pricing across complex multi-city flight itineraries.
