I use another option, because one by one often goes in the middle of the night.
I usually schedule a flight on Mon/Wed/Fri, or similar, and on the second day, I schedule a shorthaul flight (less than 1 500 nm). I take a second plane doing the same thing with one day difference (Tue/Thu/Sat or Sun), and the last day is usually day to day basis.
This way, I usually keep out from higher prices for each new route at airports, and spread two routes between two aircrafts in two days.
Just another way of handling this though...
Kind regards, have a great game !
