Once past customs, the walk to T2 is not that long (maybe 15-20 mins at a brisk pace, and with help from the moving walkways), and without bags to check, she can just head to domestic departures and reach her gate up to 20 mins before the scheduled departure time.

I reckon she’ll be at the gate around 9:15am, assuming no delays.

We landed in T3 AF from Paris and then took Aerolinias Argentinas to Buenos Aires from T2
Yes, there's a longish corridor between T3 and T2 but all we marched was something like 15 minutes, a km or so, not a mile or a "couple of miles". :-)
A recent experience, January 2017.

Is the T3 to T2 walk still 15 minutes or so and is there any security check along the way?
