For entertainment ticket websites, I find focused retailers like TM or direct Broadway ticket sites do work, but more broader travel-like ticket websites, not usually. If you mention some of the desired entertainment online retailers, maybe someone will have a data point.

My biggest disappointment overseas has been restaurants that didn't set up their merchant accounts as primarily dining establishments, but as a more generic shopping retailer. It is a small issue.

Also, while it was officially disclosed by Capital One as a change, Uber overseas was crediting at 10% rebate through the summer of 2023, it is now definitely down to 1%. I don't think UberOne is doing anything for rides overseas as a benefit either.
