Airline Reservation System Implementation Guide

Airline reservation system is a comprehensive flight booking and reservation platform integrating flight APIs (GDS APIs Amadeus/Sabre/Travelport, modern aggregators Duffel/Kiwi.com, airline NDC APIs) for flight search, pricing, reservation, ticketing, post-booking management. Airline reservation systems support comprehensive reservation functionality including PNR creation through GDS infrastructure, e-ticket issuance, EMD (Electronic Miscellaneous Document) for ancillary services covering baggage fees, seat selection fees, meal selection fees, priority boarding fees, lounge access fees, ticket reissue for itinerary changes, ticket refund processing, void processing for same-day ticket cancellation, IATA BSP (Billing and Settlement Plan) integration for IATA-accredited travel agencies, ARC (Airlines Reporting Corporation) integration for US scenarios, comprehensive booking workflow, payment integration through travel payment gateways (Stripe, PayPal, Adyen, Razorpay for India scenarios, Paytm for India scenarios), customer notification through email/SMS, comprehensive admin interface for travel agency operations, multi-language and multi-currency support, mobile capability for traveler experience, post-booking management. Airline reservation systems serve diverse operational scenarios including travel agency reservation scenarios, airline-direct reservation scenarios, OTA reservation scenarios. Travel agency reservation systems support travel agencies issuing flight tickets through GDS infrastructure with IATA BSP integration.
