Grizzler,
"it is said that eos owes servisair $744.000....but we still gave them a good turnround last night and push back......instead of keeping the plane ."
As Eos do not own their aircraft there would have little point in Servisair detaining the aircraft. All they would have succeeded in doing would have been to opening up the possibility of litigation from the aircraft owners and the passengers.
$744k is a BIG hit if none of this is secured. You are talking of c.$10 million revenue to recover a $744k loss.
