So... what happens when your 3 year commitment on the freighter is up and you want to transfer to the pax fleet on your base? Do you have to remain on the freighter until a pax F/O spot becomes available on your base and then hope you have enough seniority to be awarded the spot?
The freighter FO must have seniority to hold a pax base.
No shortcuts just because you served time on the Freighter.
Only other option is to move to HKG as a Pax FO if the company deems there to be a place available. Another thread mentions that recently the company has said that no places are open at present.
