Verdict
Serko Zeno is a modern online booking and expense tool with early, broad NDC adoption, frequently deployed by TMCs and powering Booking.com for Business in some markets.
What customers praise
Zeno was ahead on NDC direct-airline fares, unlocking fares and ancillaries that GDS-only tools miss.
What customers criticise
It is usually bought through a TMC rather than direct, and brand recognition outside APAC is still building.
Best for
TMCs and enterprises in APAC and North America that want a modern online booking tool with strong NDC content, often delivered through a TMC partner.
