I decided to post this link because I personally didn’t expect that to happen:

Regional carrier Voepass said in a statement sent to Reuters that the move was “necessary” as it now has one less aircraft in its fleet of ATR turboprops. Voepass said the measure was aimed at “minimizing potential delays and flight cancellations.” Daily flights to nine locations will be interrupted at least until Oct. 26, when Voepass will reassess its network while planning for the next season, it said.

While the article does not specify how many planes they currently have, it seems that the number falls into the “not enough” category.
