Publishes 6 October 2026. 133 pages, 6 x 9 in. Kindle, paperback and hardcover.
Airline Distribution Explained is a 133-page book about how airline tickets are actually sold: who sells them, through which channels, and what each channel costs per booking. It covers the GDS model, BSP and ARC settlement, interline and codeshare, the direct channel, direct API distribution, NDC, aggregators and metasearch, corporate travel, and the full cost map of all of them. It was published on 6 October 2026 and ends with a thirty-item Distribution Strategy Audit you can run on your own organisation.
What is airline distribution?
Airline distribution is the set of arrangements that decide five things about any seat on sale: what is being sold, who computes the price, who grants permission to sell it at that price, who holds the order, and who is allowed to sell at all. Every channel in the industry is a different answer to those five questions.
Most people learn this subject in fragments. You learn the GDS because you work with one, or NDC because a project landed on your desk, or settlement because a payment went wrong. The pieces rarely get put next to each other. This book puts them next to each other, in the order they affect each other, and prices each one.
Who is this book for?
It is written for people who have to make or defend a distribution decision: airline commercial and distribution teams, travel agency and TMC managers, product people at travel technology companies, and anyone arriving in the industry who has three months to sound like they have been here for three years.
It assumes no prior knowledge and it does not stay shallow. There is a glossary at the back and a chapter of tips for newcomers, so it works as a first book. The cost chapter and the audit are there so it also works as a reference for people who have been doing this for a decade.
What does each distribution channel cost?
Chapter 11, The Money Map, is the chapter I would read first. It sets out a method for calculating the full channel cost per booking, walks every channel through it, and shows the same booking priced eight different ways depending on how it reached the passenger.
The hidden lines are the point. Distribution cost is not the GDS fee, and it is not the commission. It is the fee, the incentive, the technology, the settlement timing, the payment cost, the servicing cost and the cost of the bookings you did not get. Most business cases I see count two of those.
Does the book cover NDC?
Chapter 8 is on NDC, and it is written to be useful rather than partisan. It covers what NDC actually is as against what it is sold as, what changed for each player, the servicing gap and what it costs, the standards politics, and a structured way for a seller to make the decision.
My own feeling is that the honest scorecard matters more than the advocacy on either side, so the chapter ends with one, including the things that have not worked.
What is the Distribution Strategy Audit?
The book ends with a thirty-item audit, grouped by the chapters it draws on, with a scale and a score card. You run it on your own organisation and it produces a number you can compare against yourself a year later.
It is free and it does not require the book. The fillable PDF is on the site, and running it is a reasonable way to decide whether the book is worth your time.

Questions people ask
Do I need to read the other books first?
No. Each book in the series stands alone and repeats the small amount of shared vocabulary it needs. Distribution and Payments overlap on settlement, and each one treats it from its own side.
Is the Kindle edition the same content as the paperback?
Yes, the same text and the same audit. The paperback is 133 pages and the diagrams are set for print, so the paperback reads better if you work through the cost chapter with a pen.
Is it up to date?
It was written in 2026 and uses figures published in 2026, each one attributed in the text. The chapters on NDC and on where distribution is going both name the date their reading was made, so you can tell what has aged.
Is this a technical book?
No. There is no code and no schema. It is about commercial arrangements, who pays whom, and what each arrangement costs.
What is the audit, and do I have to buy the book to use it?
Thirty scored questions on your own distribution setup, grouped by chapter, with a score card. The fillable PDF is free on this site and needs nothing else.
