MME4eva: Not sure about the BMI cancellation, but my guess on the GSM NCE delay would be because the NCE flights have been combined with the ALC flights, therefore the delay would be due to the aircraft having done an MME-NCE-ALC-NCE-MME (I believe).
Luke: Chances are that any "ATC Problems" would have been at PMI's end or enroute, since there were no delays as a result of Air Traffic at DTVA. Perhaps it had a flow restriction (slot time), as it seems most crews associate this with "ATC delays".
The GSM this morning to AGP was delayed due to a tech aircraft so the other aircraft operated it after it's own rotation. However, GSM were quick off the ball and had a B733 position in from EDI followed closely by a B737 from GLA to do this afternoon's rotations at a minimal delay. Well done GSM!!!
