My experience from the US is... interesting. I tapped-and-paid $700 (not a typo) when visiting NY... and American Express had no idea I was in the US (unless they cooperate with US Border Controll). In the UK, I'm limited to 30 GBP.

Did you buy the ticket with your American Express card? The data transmitted by the merchant (airline) includes some basic itinerary information.

That would be awesome if the CC provider automatically created a travel notification for you upon booking.

Some do.

Many airlines transmit level 3 purchase data as part of the credit card transaction, which will contain your complete itinerary -- which can be fed into the bank's risk system.

The next few decades of adverts that I couldn't unsubscribe from would be less than awesome though.

Amex already takes this into account.

No, I haven't, that's exactly the point! And I think that's the first transaction I've made in the US..
