Any traveller transiting through Panama's Tocumen Airport (PTY) does not need a special visa in the following circumstances:
If your layover is ever longer than 9 hours, talk to your airline about any special requirements before booking. The safe route here would be to apply to a tourist visa, though. If you have more than 9 hours to spend in Panama City, it's doable! Panama City is rather small and accessible, and also deals in USD.
In your case, it seems your flight is (was) fine for transit without a visa.
