Just remember all of you before you start bashing BA for this. Your company will be watching the outcome of this and WILL use it against any of you should you be in a situation similiar where you need to go Fatigue. Unfortunatly BA management have forgotten that to claim fatigue is not something we do because we had a few too many pints the night before BUT a very last resort in the event that there was no way for us to get adequate rest in order to operate a flight safely.
Get behind the JFK 6 everyone. It is in your own best interest, especially to those of you in the UK.
