That is completely different. In the situation I commented on, he could book non-refundable, semi flex, or flex w or without breakfast, but a 2x points rate has same terms as flex with an added benefit to him of 2x points albeit at a rate greater than flex.

Meals - you eat whatever you want, Uber whatever, as long as not excessive.

Charging a client for a rate that is higher than the flex rate so that you can pocket additional points is excessive and unethical. This would be a breach of the ethics codes for quite a few professional organizations, if a client were to discover this it could file a complaint with hotscot’s professional organization that could result in disciplinary action and/or sue him over it for over billing. This has happened with lawyers and accountants in the US and elsewhere.
