I've had to produce a corporate card from time to time for verification purpose, usually when I use it to buy tickets on the day of departure. How well it goes, or even whether it even takes place, seems to be a question of training as much as anything else.

The worst case was in BRU incidentally, where I booked BRU-FRA-YYZ about four hours before departure. AC flagged my card for verification but the LH staff (for the first leg of the flight) first wasn't aware that verification was required (took them 15 minutes to figure out why they couldn't check me in) and were then unable to verify my card in AC's system. I ended up buying a brand new trip on a personal card from LH. Bottom line, hassles for me, and a lost Exec First sale for AC to the benefit of LH.

I guess it depends from card to card and/or country to country. I have 90 days to initiate a dispute for most of my cards.
