When
Before you sell a fare — and every time the client asks "can I change it?", "is it refundable?", "how long must I stay?".

The rule text appears in English, grouped by category.
Traps
- Rules are written per fare component; a return may have two different rule sets.
- "Non-refundable" often still refunds some taxes — the refund card explains (Full automated refund (TRF)).
- Outside the terminal, fare conditions are often summarised or missing, so the terminal
FQNis the place to read change and refund conditions.
