Learn codes in context
A code like SIN, DXB, or ORD is easier to remember when you see the airlines, routes, region, and city attached to it.
Two ways to practice
AirlineQ is the direct airport quiz. AirportQ is the map-based version, where the hidden airport is inferred from its nonstop network.
Useful for aviation and geography fans
The quiz rewards both aviation memory and map reasoning, which makes it more useful than a flashcard-only list of IATA codes.
