There is various rumours doing the circuit however what is known is that currently there is a Links Air - Jetstream 31 based at Cardiff to operate the Valley service.
There is also a 2nd Links Air - Jestream 31 based on the Isle of Man. A month ago the FLM Aviation - Dornier 228 moved from Cardiff to the Isle of Man to join their 2nd aircraft.
For whatever reason it appears that FLM aviation no longer operates for Manx2.com. Therefore Links Air has 2 x Jetstream 31 & Van Air 3 x LET 410 operating for Manx2.com currently.
