When I read this I get the idea we could have a cascade effect. But not necessarily.
An excess bid for 727 FO could cause Airbus guys to get bumped back down to the Boeing. That is why, IMHO, Cassel said we could have an excess bid in the Airbus. It depends on how many relatively senior 727 FO's bid up and where they bid to. If they bid to the MD11 the Airbus may not get an excess bid.
