Apologies, I'm sure this has been discussed before, but a quick search on here didn't turn up anything definitive and lots of conflicting information on the broader internet.

We will be arriving at 2F and departing from (likely) 2E Hall K, with a long layover in-between. Not a big fan of the AF business lounge in Hall K, especially for a layover of a few hours. Is it possible to alternatively use the lounge in Hall L?

Some say that, aside from allowing enough time to get through multiple security checks, this is possible. Others say that security scan your boarding pass and will not let you through if the boarding hall on your pass doesn't match the one you are trying to enter.

Any recent experiences appreciated.
