Sorry an-124, but the facts are thus:
Atlas is its own worst enemy.
It operates ACMI and Polar operates right along side, and quite a few customers of Atlas are not at all pleased.
Some Atlas ACMI customers feel that Atlas is undercutting their cargo service with Polar...oftentimes right along side at the same airport.
I didn't realise the animosity caused until a recent business meeting and heard complaints first hand.
Of course it might be worked out, but the folks I know (all very knowledgeable in freight) are betting otherwise.
