I sent to LATAM exactly from now a week ago an email requesting a status matching with United (1K). I argued that I did 3-4 trip between Europe and South America per year. Currently I am 1K in United's Mileage Plus and I am almost to get 1K for next year (I have a trip next week and I will reach 1K again). I already sent all the information of my statement for whole 2017, forecast of my status at the end of 2017, my card and two boarding pass of two trips in the last month with LATAM (LIM-JFK and GRU-LIM). The email was in Spanish.
I didn't get any reply yet (besides the automatic reply with case number). What do you suggest to do? wait or send some message by Facebook (I dont have twiter)?
