I don't think so.
I have a US passport and a UK passport. Whenever I travel to the States, the check-in folks always check me in with my US passport.
But I always enter the UK on my UK passport (actually I go through IRIS when I can, but it's linked to my UK passport).
Surely there would be huge confusion if the airline reported me having left on my US passport, but immigration had no record of my entering...?
