Just to complete the picture, I tracked down a single ATR 42-300F that is supposedly
operated by Hello Airlines under wet lease from a Lithuanian operator called Danu Oro Transportas (DO LT) - see

The aircraft in question could be LY-OOV (c/n: 005), previously registered as EI-SLD (Air Contractors (Ireland) Ltd).
This 28-year old aircraft is seen here at LOS (note the B.727 in the background!) operating for DHL in 2011/12.
