Hi. I'm based in London having relocated from Malaysia and am trying to gain status towards a oneworld frequent flyer program. Problem is that I have MH Enrich and BAEC, both blue, and also am trying to rack up avios via different means (amex, nectar etc). I seldom fly BA previously but am doing so more due to work and use MH to fly to Asia to visit family. Which OW FFP should I commit to here? Should I continue with MH while holding some avios from credit card spendings, or commit entirely on BAEC? Appreciate any advice!
