Not exactly lowerlobe...
Jetstar Pacific Vietnam is the old Pacific Vietnam that Jetstar bought ages ago (VN rego). Based HCMC. The original Pacific 737s are getting replaced with new A320s, but they've been flying 737s in Jetstar colours for quite a while now!!
Technically no existing Q pilot has flown it, but there are a small handful of guys up there on secondment/LOA etc, as their next Chief Pilot may indeed be.
