How does the Ponant flight credit offer work?

[vicd1969]

I see some Ponant cruises on its website are offering a flight credit. How does this work? Is there a flight booking portal that Ponant has on its site? How was your experience using the Ponant flight booking site? Their Antarctic flight credit amount seems very substantial.

We have done this once in 2019. Ponant simply reduced the cost of the cruise by the amount of the credit. 
 

Agree it’s substantial.
