US negotiator was very casual about the cost of dual divisions at US - "we've had it before and it's not that difficult." APA estimated the loss at LAA, with 8,000 pilots, at 85 jobs. So what's the job increase at LUS with fewer bases/bid statuses and half as many pilots, 35? 40? 45?
Even if you don't believe those valuations no one has mentioned valuations that come anywhere close to $875 million.
