LMX:
was it EOBT+13 or TOBT+13? In a properly run A-CDM environment, that makes a lot of difference. If, indeed, you became subject to flow management control, even worse (in order to try clarifying).

some time ago, with a CTOT of about STD+32, we were ready for start up at STD-30. Called the OPS to asking to re-file so that the newSTD was origSTD-25. The idea was, we are ready to take 25 minutes delay as assigned, but filing an earlier STD would enable us to depart effectively on time.
The answer was a cold "NO" (from Company folk that is), with explanation that CTOT are being assigned on a first-come, first-served basis and so we would join the queue at the end, even when asking for an early STD.
Does that make any sense?
