Roller powered 767s
I believe that the only taker for the RB211 powered 767 was BA. They then of course leased some (7?) across to QANTAS.
BAs original disposal streategy for at least some of the 767s was to the RAF as tankers, but the A330 won that competition.
Since then money has been spent on the long-haul configured 767s for lie flat beds, but I believe there are some Eurofleet machines.....if Jet2 could source some of these I suppose there would be some engine maintenance commonalities to the 757s for Jet2 that would put most other 767 operators right-off.
