newspaper reports say A310 (OTOH, aerotransport.org doesn't show A310 for MNG)
The problem is until now there are only reports from pax and they were saying it was an aft pax door (maybe not sealed correctly) and that it got cold, even after the CC managed to "fix" the door problem.
EDIT: found on a german spotter forum
