I would not be at all surprised if a new longhaul low cost subsidiary is formed at LGW due to the base losing money using Mainline pilots. As it is Willie's aim to have a premium world airline with a low cost base, you can see a BA version of JetStar coming.
If the vote had gone the other way, then those in IAG (and there were several big hitters) arguing for a "BA Jetstar" rather than the integration route, would definitely have had their way. BA Jetstar would be a certainty and not something that the Count, with his cracked crystal ball, could "see coming".
There is much talk of a divided pilot work-force within IAG, how much less fractured will that pilot work-force be now that ALL BA pilots (BA and Ex-BMI) will be represented by a single CC and cannot be played one against the other?
The Count is still trying to enjoy a Scadenfreude moment, sadly for him and his seriously flawed thinking, this moment has been seriously delayed by the vote.
