That's not quite how I'd describe it - T1 and T2 are directly adjacent - they may as well be the same building. It's basically like walking from TBIT to T6 at LAX.

PRG is a fantastically efficient and compact little airport. 2 hours should be enough for a very comfortable connection,
Even if AA were 45 minutes late and if you had checked bags, I would think you should make it.
