For me, hitting LTG was the trigger to stop building in routings solely created for the purpose of maximizing TPs, but I still concentrate my flying on OW whenever possible (although no longer BA, since I live in the US and no longer fly internationally for business). The whole point of LTG, as I see it, is to get benefits when flying OW. So it wouldn’t make much sense to suddenly stop flying OW, having attained LTG.

It is a relief to be able to fly straight to Hawaii now without going through the Bahamas first though
