It's all well and good complaining that seniority isn't fair (I might even agree) but it won't be germane to this debate, which will be settled long before anyone from Bmi see's the inside of a courtroom.
Likewise, people can grumble about BALPAs advice re the bmi/BMed merger but it has no bearing on the BA/bmi takeover. You can gripe with BALPA about it, it won't be influencing the BACC or BA pilots.
