Thanks LupineChemist, and of course you're right. It's MUC-MAD tonight...
Yes, I was wondering about minimum check-in time.
And craigthemif, I'm almost with you on taking the gamble... I had been looking on BA and they only had availability in business, but I've just checked on iberia and they have economy. It's still 6,750 avios plus 32 euros, mind, so I still have a little pause for thought...
I might wait until we're boarded at MUC and press the button if it all still looks good. Agree that the usual padding in the schedules should make it very do-able.
Thanks again
