Hi, I am new to the forums here, thanks in advance for your advice.

I am currently a member of both skyteam and oneworld. Most of my miles are with skyteam (delta) but i have no eqm segments or miles with them. I have a few eqm segments/miles with oneworld (american).

I will be travelling from BOS to RDU quite frequently, with the occasional trip from BOS - MIA/EYW and BOS - LHR and am trying to decide which airline to stick with.
