It's usually done by phone and email. If you are on this sort of group booking - and indeed more generally - just ensure your BAEC number is on any booking and usually it all works automatically. If it doesn't then yes Claim missing Avios is the place to go, but on BA metal it rarely happens if you have your BAEC number in place and travel as planned.
