guys, I'm going to split strike dates off into a separate thread with it in the title... not everyone may be keeping up with this thread.
heregiam, welcome to FT - not under best of circumstances. You are correct, they either have to have given notice of future strike dates in the notice they are apparently sending in tomorrow, or will have to give notice once again.
I wouldn't make bets about domestic being hit harder than long-haul. If enough crew go out, it will hit everywhere, because you can't take domestic crew and put them onto long-haul if they are not trained for the aircraft type (for example). However, I would imagine BA's contingency plans may be aimed at protecting long-haul more. OTOH, if you are on a through PNR, and it's by their action you cannot make the connection, its their responsibility to get you there.
