Except that even the mighty Parker can't predict the future. There will be lots of numbers showing how it will work under a given set of assumptions. The true test for the UCC and possibly then the investors is to determine whether the assumptions have a good chance of being valid or are pie-in-the-sky wishful thinking. Generally speaking, no airline merger has produced the amount of "synergies" predicted. If I remember anywhere close, the US/HP merger was supposed to produce something like $500 million profits for 7-10 years....how's that coming?
Just ballparking it, I figure he's promised about $1 billion in extra costs - just keeping 6-7000 more people on the payroll is half of that so it could easily be more.
