How on earth has BALPA been allowed to agree such punishment on the rostering systems , especially in LH. I retired on the B744 when BA were only allowed to roster 4 Atlantic crossing trips per Bid Period. You could bid for more in MU1 or Open Time, but that was your choice.
Preumably todays pilots are suddenly immune to fatigue as far as BA/BALPA are concerned. And if you did agree to help BA on last minute uncovered trips you could pick up £2000ish overtime to Syd.
