Data point: I reached out to the Twitter team because I have an upcoming trip LAX-LIM-GRU-IGU-LIM-LAX, all in O and Q classes on LAN (except for GRU-IGU which is on TAM). Angel said they would put a note on my account that the flights should be eligible for mileage credit, which with my other travel plans for the year should put me over the threshold for MVPG again for the first time since 2008
