BA's strategy for recovering today's MAN Shuttle backlog is a very interesting development. In the past, suggestions that a larger type could be drafted in have been knocked back as impractical because long-haul aircraft are crewed by a different division within BA. Hopefully, following today's precedent, we can look forward to more flexibility from BA in addressing similar problems in the future. It bears watching anyway.
EDIT: GRRR ... I see that my word 'following' has been changed to 'foolwing'. I noticed a couple of others earlier and wondered why my typing was so bad today. And I did a major software update on this machine last night. It looks like they've sneaked in another 'spellcheck' activation. Now let me just go off to strangle it at birth!
