Just checked & it would appear to be operated by Titan at the mo'......flights are certainly listed as being on an ATR42......

PS Happy Landings.....breathing O2 either from the a/c therapetic system or on board O2 bottles would do you no good as the masks used are there for decompression/medical situations only, as you are also breathing the ambient air. Normal procedure for cabin crew to instruct pax to breathe through a cloth/towel, preferably damp, & to stay under the level of the smoke/fumes.
