The Republic/Northwest merger resulted in 20 year fences!!! The NWA/DAL merger resulted in......wait for it......5 year fences around the 777/747/787 from date of SOC. Of course the 787 fence was pointless, but the arbitrated list came out in 2008 with the 787 schedlued to be in service in 2010. And to be fair, Delta/NWA both brought WBs to the merger. Republic did not. Hard to guess what any arbitrator will do.
