Airlines have been trying to modernize their retailing for over a decade, and most still can't change or refund what they sell. Ann Cederhall is co-founder of LeapShift and one of the architects of the original NDC Direct Connect implementations at Lufthansa, where she helped build the project that became known as the "16 Euros" surcharge. In this episode, she traces the structural reasons why airline retailing has stalled: from the servicing gaps baked into NDC standards through version 24.1, to the 70% of airlines operating without any order management system, to the $650 million to $3 billion in annual revenue leakage from interline proration disputes. The conversation covers what AI can realistically fix and what it cannot.
What You'll Learn NDC servicing gap: Airlines could book via NDC from 2012 but could not change, cancel, or refund those bookings until the 24.1 standard in 2024, a 12-year gap that fundamentally limited what airlines could sell through the channel. Version fragmentation: Approximately 70% of airlines currently on NDC are still running version 17.1, leaving them without the servicing capabilities that would make the standard commercially viable. Order management absence: Nearly 70% of airlines surveyed have no orchestration or order management system, meaning they have no centralized control over what they have sold, to whom, and what can be changed. Ancillary inventory failure: Airlines routinely sell ancillary services (seat upgrades, fast track, bags) with no system to verify that those services actually exist at the time and place of purchase. Upgrade opportunity cost: Willingness to pay increases sharply close to departure and at the airport, but most airlines' systems cannot process an upgrade when the booking is held in a travel seller's PNR rather than the airline's own record. AI's real limits in retailing: Agentic AI can filter and interpret shopping results, but it cannot replace shopping engines that have not been modernized in 30 years and still process 20 million fares to surface a handful of relevant options. Revenue management transformation: AI agents can harvest competitor cancellation rates, demand signals, and real-time market data overnight and present a synthesized briefing. That is a significant shift from traditional RM systems built on historical averages. Revenue leakage scale: Global interline revenue leakage runs between $650 million and $3 billion annually, driven by inaccurate proration calculations, uncollected taxes, missing ancillary settlements, and unsettled ticket coupons. Many of these disputes cost more to resolve than the amounts in question.

An AI asked to protect every passenger connection gave a flawless answer: cancel the flights. Kevin Hightower is Chief Innovation Officer at Cirium, where he leads Propulsion Labs, the company’s innovation group. He and host Alex Brooker, former colleagues at Cirium, discuss Kevin’s path from oceanic air traffic control at Lockheed Martin to Google’s drone delivery program, how AI is changing product development and decision making in aviation, Cirium’s aviation knowledge graph, and the data interoperability problems holding the industry back. What You’ll Learn Automating the routine: Lockheed’s oceanic ATC system let controllers comfortably manage 30 aircraft instead of a busy 7 to 15 by automating conformance checks and altitude probes. The three hour rule: No decision, from buying a car to buying a company, should need more than three hours of actual thought, with data gathering kept separate from thinking. Disposable prototypes: When AI cuts build time from months to days, the discipline shifts to throwing work away instead of defending ideas because of the effort already spent. AI as an accelerant for learning: Early career engineers who use AI to compress years of learning will outpace those who use it only to do an old job faster. Decisions, not dashboards: Most aviation decisions run roughly eight steps, and AI can now carry four or five of them before a human makes the call. The aviation knowledge graph: Aviation data starts with an aircraft and links orders, lessors, schedules, and tail swaps, so connecting it unlocks analysis no single dataset can. Efficiency before safety: AI will speed up flow management and sequencing well before it touches the safety critical systems that keep aircraft separated. The interoperability gap: Multi year, multi million dollar data lake programs rarely deliver usable value, and the real problem is combining data across boundaries while keeping control of it.

AI made writing code nearly free, which only matters if code was ever most of the job. In this compilation episode, host Alex Brooker pulls together clips from seven past guests across travel software, airspace infrastructure, airline operations, corporate travel, content, and airline ancillaries who each arrived at the same idea independently. Alex Ragin of Zoftify puts a number on it: code is about 20% of a software product, and the other 80% is domain knowledge, process, and judgment. The episode follows that 80% through edge cases, daily operational disruption, fare construction expertise, and the question of what a product team's job becomes when execution costs almost nothing. What You'll Learn The 20/80 split: Code is roughly 20% of a complex travel system, and the remaining 80% is knowledge of how the business actually works. Vibe coding limits: A simple invoicing app can be vibe coded, but a CRM, ERP, or GDS cannot, because the hard part is specifying behavior rather than writing it. Edge case cost: One modest custom fields feature at Zoftify took about five days of internal and client discussion before it was ready to build. Failure at the seams: Complex systems break at their interfaces and edge cases, not on the happy paths that teams test and load test. No standard day: In airline operations, disruption from weather, aircraft swaps, or system faults is the normal state rather than the exception. Expertise outside the code: International fare specialists routinely beat GDS pricing engines by thousands of dollars by knowing where to break a fare. Where value moves: As development costs approach zero, advantage shifts to network effects, knowledge of customer pain, and position in the customer journey. The new job: When execution is cheap, deciding what to build and why becomes the core work for every team, not just well funded ones.
Two euros can decide who wins a metasearch sale. Inside most airlines, moving them is still revenue management's call, and it is rarely fast.
Everyone is racing to build the AI agent that books your trip, and nobody is building the thing that makes it safe to use one.
A guy who used to hand carry passports to airport cargo terminals just built the database he couldn't afford in 2018 for a fraction of the cost, and every application still passes through a human before it goes anywhere. Rob Lee is CEO and co-founder of Swift Passport and Visa Services, a company he started in 2008 helping private aviation clients navigate passport and visa logistics. In this conversation, Rob traces the industry from same day passport courier runs through the shift to eVisas and ETAs, and explains why his team uses AI heavily to build internal tooling while keeping customer data out of public AI tools and a human check on every application.
