From first principles to airline-scale retail architecture
Choose a path, work through practical explanations and use the linked tools to test what you learn. Progress is stored only in this browser. The paths are vendor-neutral and separate industry standards from implementation choices.
How to use these paths: read in order if the subject is new, or jump directly to the capability you are designing. Mark a module complete when you can explain the concept, identify its system owner and describe its lifecycle impacts.
Understanding Airline Retailing
Build the vocabulary and mental model behind shopping, offers, fulfilment and orders.
Retail Architecture
Connect product, price, availability, payment and accounting capabilities.
Order-native Platforms
Design system boundaries, event contracts, observability and migration controls.
Follow value through the retail lifecycle
The flow is not a single system sequence. It is a map of commercial dependencies: inventory constrains availability, availability informs pricing and offer construction, the accepted offer becomes an order, and fulfilment events feed settlement and accounting.
