And the "Union" distinction between long haul and short haul cabin crew is largely history. The MAN-LHR route is operated by "mixed fleet" cabin crew who are licensed to operate on multiple aircraft types, including long haul aircraft such as 744s and 777s.
The 744 yesterday was operated by Mixed fleet crew, the 767's yesterday and today were operated by Euro fleet crew due Mixed fleet not being licensed on 767's. MAN is operated as a Mixed fleet route.
