very long flights

[lord voldemort]

Hello,
What should be strategy in scheduling very long route flights ( > 5000 nm)?? Because it takes more than 24 hours for flight to return. Should such flights be scheduled every alternate day or flight should be scheduled 5 days a week with different timing on each day?

7 planes scheduled as a group, so you fly to the same place at the same time every day with one of the 7. Search for '7 day scheduling', there are plenty of threads on it.

Does anyone know if put one aicraft in a 12345-- and another in -----67 solve this problem?
And if a b-check in a route (I know that a profit will be ignored in this route), if I remove this flight during the day (during b-check), will harm my LF%, or my route image?
