happenchance

Unplanned fortunate occurrence

Happenchance is a blend of "happen" and "chance," meaning a coincidental occurrence or lucky accident.

It's a playful, somewhat redundant formation—chance already implies randomness—but the doubling emphasizes fortune's role: By sheer happenchance, we ended up on the same flight.

The standard term is happenstance.
