Hey guys, I've never flown with OW before but I have a few flights booked on AA and MH this year and want to know what the best option was to credit points to. I'm anticipating lots of transatlantic flights in the coming years since I'm moving from US to UK and will be going back to visit family a couple times each year in the US. I'm currently looking at BA or AA. Does anyone have any advice or better options that I'm not looking at? The airports I'd be flying into in the US often would be MSY and LAX.
