This has probably been posted elsewhere before but I can't find it. BA.com tells me that I can earn tier points on these fare classes domestically: 'UK Domestic Y,B,H or C'

And on these in Club Europe and Club World: 'Club Europe & Club World (business class) J,C,D or I'

But aa.com reminds me that J is now a booking class domestically e.g. MAN to EDI.

So, on which fare classes can I earn miles domestically? And if the website is not up to date, why not?

Grrr.
