The age of the intercity 50–90 seat prop plane is coming to an end. The last Bombardier Q400 (Dash-8) rolled off the production line in 2022. Similarly,
SAAB 2000 production ended in 1999, the
Fokker 50/60 ended in 1999 and the
BAe ATP in 1996. With the
Airbus C295 now being exclusively for the military, the only prop airliner in this category still in production is the
ATR 72, which no North American passenger service uses. Though as the last remaining, and therefore
monopoly player in the regional prop airliner space, they seem to be seeing some
immediate success in this otherwise declining market.
If YTO doesn't switch over to jets, it's only a matter of time before there are no commercial passenger aircraft available to operate from this airport. Which I suspect was the unspoken hope of those who want no commercial airport whatsoever on the islands. With the scarcity of prop options, by the end of the 2030s it is more than likely that commercial passenger flights into YTO will be ONLY jets.
