In spring I will most likely move from Munich to Dallas. I am currently Flying Blue Platinum / SkyTeam Elite Plus. Since Delta does not have a lot of business in Dallas I was looking into doing the status challenge with AA with my relocation flights, it looks like I could reach both the Gold and the Plat challenge. Possibly I will make two return flights, with Premium Eco on the day flight and Business on the night flight. If I understand the EQM table correctly it is better to use qualifying partners' marketed flights for Premium Eco (e.g. BA flight number --> 1.5 EQM) and AA marketed flights for Business class (--> 2 EQM). Am I right?
