I have a few points with ba and qantas as well as various other ff programs. I have no control over whichever random airline my employer books.

I am wondering however if I am misunderstanding how I should be using ff programs. For example, if I fly with qantas more frequently should I be having whatever ba flights I take credited to the qantas account?

I mean, is it impractical to collect points with every ff program? For example, if my employer books me a flight with qantas but I have a stack of points with ba, how do I use them?

And if by some miracle I have enough points for a whole flight between the two combined, how would I use them?

In my opinion it seems the issue is that there is no way to consolidate points... So how do you work around that and how do you get the most benefit, or any benefit, out of the ff programs?

Thanks!
