Rumors, Rumors & more Rumors. ATRs have been parked (3 of them so far). The ATR flying has decreases as more flying is shifted out of San Juan (Eagle ATR) to Miami (AA 737). Miami ERJ base is up and running so some of the ATR flying out of MIA has decreased as well. We are in the slow time of the year and some of the ATRs are approaching heavy checks and the age of the airplanes will lead to them being parked. AMR is painting the airframes with the most life left, so you will see them fly a bit more.
