I'm expieriencing this same problem at LEMD. Specifically, I have a couple of TWA flights from LEMD to LIRF that are sitting on the TARMAC at LEMD on Sundays. These flights don't even operate on Sundays.I've checked the flightplans in AITM,and this is not the result of long layover times. I've tried different AFCADS for both LEMD and LIRF, with the same results. I can't figure this one out.RPM.
