I can't believe that anyone who flies for Delta wouldn't know why. Mostly because Leo Mullin was stupid, and Richard Anderson is not.

Different timelines, too:

POS 96
+ NWA lockout
+ Delta Dot with 777 rate
+ UAL contract
- overtime antics by DAL pilots
+ management missteps in hostage taking and a trip to court
----------
Galvanized pilot group and good case at NMB, resulting in C2K (albeit with scope clauses that would be rejected out of hand today).

Versus the current narrative:

Ten lost years
- merger madness (look at how consolidation impacted rail workers)
+ JCBA
- knucklehead strategies at APA and USAPA
+ C2012
+ UAL contract
+ AAL contract
----------
Equals our current situation today.

C2015 if the pilots want it, and a trip to the NMB if they don't. A test between one argument based on the market, and another based on fairness. The company saying "we clearly want to get a deal," and the union saying "the highest pay rates, best work rules, and best profit sharing in the industry isn't enough for us - we want more."

What's your BATNA?
