So, let's say a destination has, on average, a demand of 30 pax/day. If I flew a flight to that destination once per week, would any of the other days' demand spill over? For example, at 30 pax/day, that means there is roughly 210 pax/week in demand. Could I fly a 180 pax flight once a week and have sufficient demand or no? Thanks.
Nope. Demand does not "transfer" to other days.
It would be nice if they did. There have been a few threads about this -
