Thanks for that. I must admit after I posted that, I did have a nagging doubt about LGW Carmen, but I asked my ex EF LGW wife and she thought it wasn't seniority based. Hey ho!
Anyway, point still stands that the main thing standing in the way of Carmen bidding working for LHR WW is current allowance system, which makes the same trips popular for most people.
