If it is not in the list of classes that earn I suggest you anticipate it doesn't earn. They usually list classes that don't earn separately, but this list is not always up to date.
There is a lot of classes that earn differently here than in other programs, so I wouldn't take the comparison of G in other programs (or G from other carriers) as any proof of the opposite.
If the miles are not so important to you and you want to try it out, you could fly without adding any FF to your BP. Then retro claim with A3. If denied, then retro claim with another program. But you stand the chance of not getting any credit anywhere of course.
