Aerolineas Argentinas are still offering a status match to elite members from competing non-Skyteam airlines, namely these these ones:
I took advantage of this match on 4th January 2013 and and they got back to me after 2 working days (8th January) saying my American Airlines Platinum was successfully matched across to Aerolineas Plus Oro tier. It's taken a while and I only noticed this afternoon that my online account with them is now reflecting my new upgraded tier.
If you did your status match last month, maybe you should check your account too.
You will need to email email@example.com with the subject “Elite Status Match”, providing your Aerolineas plus account number, full name and a print-screen of your transactions of the account you are matching from.
I look forward to seeing my shiny new card when I get home and seeing what benefits Skyteam Elite brings, especially at AMS where everything seems so Skyteam orientated.
