may I take it then you agree with the rest?
But seriously if flights were intentionally rostered one light - this payment as a stick for BA is fine - but it rarely/never is intentional (the company can't afford for it to be) occasionally it is even another crew members fault, or, an unavoidable operational reason yet with a crew of 15 on a 747 on a simple round trip the extra costs are £6000 - this money doesn't come from nowhere - and that effects our colleagues beyond the CRC.
Careful and effective IR could achieve the same goal as this carte blanche allowance - and then there are diversion payments...... These unusual one offs don't form part of our regular or predicted pay packets so they are non-painful ways the crew community could bargain..
