But you can collect points on UA/US/soon CO/BD/LH etc. and use them on AC domestic flights, etc., and that's the point.
And for those referring more broadly, then you have WS and Air Miles or Porter and VIPorter or Via and Via Preference. But don't start up with that crap of not having domestic competition. You also always have the choice of making your own FFP and just fly the cheapest always. Vote with your wallet and pick your poison.
