How long are people going to whine about Bloch, the SLI & who bought who? Get over it already. There's absolutely ZILTCH anyone can do about it. If it's that bad, then quit. This was not a integration based soley on longevity, it was based on many other things. The ALPA "merger policy" doesn't mean squat - it was an arbitrated decision.
What's funny is if you look at the PNCL stock price from the Colgan purchase until 6 months after the Mesaba purchase. Now ask yourself what what really was brought to the table. This might be a stretch for you Riddle super-pilots with your worthless Professional Pilot degree, but for those with actual educations it might make sense.
