As easy as the Topic is.
Which airlines use short-haul equipment abroad. I know that
AF uses A-32X in MIA as
IB does or have done the same
MP uses an leased A-320 in the US
Aerolineas Argentinas has a 737 at MAD and had a MD-88 at MAD in the past IIRC.
Any more airlines or more info about Aerolineas Argentinas at MAD?
