I flew HER-ATH with OA in Jan 2000 and I recall the overhead bins. It must have been a 737-200.
I knew the 727s had that "flat-door" style of bin but I couldn't remember what the 737-200s were like, although I flew on many of those too. In that case, it's probably filmed in the 737-200 Cabin Trainer SX-BCL which is "parked" by the taxiways at ATH. One would assume the interior of that is in somewhat better condition.
