I'm a relative newbie here, based in KMIA and a bit puzzled by an issue. I have scheduled two European flights using DC6B aircraft, one to EHAM the other to LFPO both with a tech stop in LPLA. On the outbound flight my available seat is 90 ( limited by range of DC6) but on the return flight limited to just 7 seats!
The distance is the same, so I though maybe need to account for jet streams then but I noticed another operator flying out of LEMD to KMIA with a tech stop in LPLA and their capacity is same both ways?
Why am I not getting same seating capacity on return flight? The longest sector of the route is the flight between KMIA and LPLA, but the guy flying to LEMD is not limited like I am.
