On both flights to and from LHR last week, at least 2/3 of the FA's looked as if they were under 30 or 35 years of age. Maybe because it was a newer plane (A330)?
Compared to CP flights I used to take to LHR when they were all oldtimers - and a couple looked like they should have had their wings clipped! (How's that for being ageist!?!)
