MT Qatar,
I am looking at the GF timetable right in front of me. No 340's to DMM. Maybe they did so on the past, but not anymore. As for JED, don't they use that for Umrah and for labor markets connecting to MNL? You also have to take the planes to AUH for maintenance, so in certain cases, you have no option but to use them in certain intra-gulf sectors.
