Reserve on an ad-hoc basis was voted out when TCAS ran the vote to either keep it or have like the BA system once every second rotation.
From what l understand BA have reserve once a year. Not every ten months.
Reserve is one month, not five weeks.
They also get 8 days off pre-assigned that is pre-selected by the pilot.
As TCAS is leaving, then maybe so is the instilled reserve system?
