What is Airlines & Booking?
Airlines & Booking encompasses the technology behind flight search, reservation, ticketing, pricing, and distribution. At its core are Global Distribution Systems (GDS) — Amadeus, Sabre, and Travelport — that connect airlines with travel agents and online booking platforms. India's travel tech sector is booming — MakeMyTrip (India's largest OTA), Cleartrip, ixigo, and EaseMyTrip process millions of bookings. Airlines like IndiGo and Air India run complex Passenger Service Systems (PSS) managing reservations, inventory, and departure control. Revenue management uses ML to dynamically price seats — the same seat can cost ₹3,000 or ₹15,000 depending on demand, booking time, and competition. Understanding this domain teaches you complex distributed systems, real-time pricing, and high-availability booking engines.
