Title says it all. Sometimes small regional airlines like mine will use cities with smallish demand to fill in 7 day flight schedules (the other, more profitable flights will compensate this) simply because they fit in to desired slots for serving other destinations. It is a massive pain in the rear to have to go pax limit 7 flights that now show an oversupply due to this.
How about it?
Also, would solve some of the problems caused by asymmetrical routes (in Asia), until CBD gets implemented for pax.
