Yeah, actually they do. I’ve been working for a wealth management bank in Luxembourg for several years, and we do have unlimited credit cards. Technically they have a 999,999,999 EUR limit since there needs to be something, but good luck spending this much anyway.

Also, credit card fees outside of the US are rather tame in comparison, and usually even capped. I’ve seen someone buy a Bentley worth >1M with his Visa.
