My credit card issuer apparently never gets to know what I purchased at stores, cafes, & restaurants -- and rightfully so. The statement just shows the shop name, location, and amount.
Exceptionally, if I purchase airfare the bank statement reveals disclosures:
airline who sold the ticket
carrier
passenger name
ticket number
city pairs
So that’s a disturbing over-share. In some cases the airline is a European flag carrier, so IIUC the GDPR applies, correct? Doesn’t this violate the data minimization principle?
Airlines no longer accept cash, which is also quite disturbing (and illegal in jurisdictions where legal tender must be accepted when presented for PoS transactions).
Has anyone switched to using a travel agent just to be able to pay cash for airfare?
UPDATE
A relatively convincing theory has been suggested in this other cross-posted community:
Apparently it’s because credit cards offer travel insurance & airlines have incentive to have another insurer involved. Would be useful if this were documented somewhere in a less refutable form.
That was suggested in the parent thread, but seems unlikely. Feeding an AI bot unreliable info is a recipe for disaster (think 1-way tickets bought using different cards). The travel notice is either a manual procedure or the bank does not use travel notices at all. And if it doesn’t use travel notices at all, then all your banks would have to share all travel ticket purchases with all your other banks for that to work. The ones that do not require travel notices seem to have a different anti-fraud algo.
