OltonPete is the expert on this, but I cannot see that the winter schedule, which appears to be 13 departures per week is ever going to keep two aircraft busy - though I grant you that things might be a tad tight on Monday and Thursday.
I haven't looked at the timings but, if on the aforementioned days the AGP and FAO depart EMA at ca. 07:00, they'll be back in around 15:00, in time to take out ACE at ca. 16:00, which would be back in the middle of the following morning. Not great for the PAX, but it would negate the requirement for an additional airframe on any day of the week.
