Show Notes
Behind the sleek interface of your favorite travel app lies a fractured world of 1960s mainframes, cryptic UN-standardized messaging protocols, and a mountain of technical debt that makes modern flight booking a digital ghost hunt. This episode explores the "Big Three" Global Distribution Systems—Amadeus, Sabre, and Travelport—uncovering how decades-old Transaction Processing Facilities still dictate the price and availability of every seat in the sky. From the rise of the New Distribution Capability (NDC) and the "Dual Track API Tax" to the hidden complexities of interlining agreements and the "Look-to-Book" caching traps that cause prices to vanish at checkout, we break down why building in travel tech remains one of the most difficult engineering challenges in the world today.
