L337
Agreed,
The commuting seems to have brought out the green eye in some. Some crewmembers (pilots and cabin crew) choose to commute, in their own time and at their own expense. The only caveat is that they should be adequately rested for Duty. As you say, most of those who commute "Long Haul" arrive in the UK 24 hours ahead of their working flight to ensure they get adequate rest prior to duty. As an aside some with control over their rosters then operate back to their "home" airport, so they are probably in a better shape with regards to "jetlag/acclimatisation" at destination than the UK resident crew members.
As for the shock/horror some have expressed about the commuters only having one night off between Longhaul sectors - as has been previously pointed out that happens to all BA Longhaul crewmembers on most trips (JFK/IAD etc etc etc); feel free to call the CAA and/or the CEO if you think it should be stopped.
