gdukkoq,
Thanks for response. Again, if you are "offered" specific positions, I guess that means you can't bid a preferred aircraft? So, as example let's say you are from Brasil and you want to be able to fly to Brasil in the future. If you are currently flying the A320, what is possibility that you could bid over to the 777 so that you could visit home again? If you are only offered A320 and A330, then that would not be a possibility.
Just trying to understand what flexibility you could have with fleet bidding if you don't start with your first or preferred choice. I realise choice may be limited in this type of company (and country), but trying to understand flexibility.
