I'm of the understanding that the platform was a goal not a floor. SWAPA got...

$280/HR final pay or 97% of the platform and above DAL's company offer.
15% B fund or 94% of the platform.
100% retro with the limits imposed by the previous NC. They hosed us on that.

I'm not sure how this is concessionary. You never get 100% in negotiations. Throw tomatoes if you want but I commend the NC.
