Why am I surprised?

I forked over £600 for my daughter's flight to the UK this Christmas and BA cabin crew (the highest paid in the industry) decide to go on strike, causing the cancellation of flights and skuppering holiday travel for a million paying customers.

Just praying that her flight on 17 Dec. is not effected by the strike action which actually starts 22 December and ends 2 January. BA says this can effect flights 48 hours on either side of the dates. Her return may be messed up though.

Boggles my mind that these guys always opt to strike when either myself or a family member is travelling with them. Am I unlucky or just plain stupid for booking with them?
