Visa - Always Looking Out for Me (NOT!)

After years wandering in the wilderness, I finally have great credit and a huge credit line, but everytime I make a big purchase online (usually airline tickets), VISA has to refuse the payment till I call them up and clear it with them. Of course, since I'm not liable for fraudulent charges, all their talk about protecting my credit is bullshit: they're only protecting themselves, so the whole thing does nothing but inconvenience me.
