Not exactly.

Try buying a NWA ticket just a couple of months after DCC. You won't be able to.

Try finding a "NWA" pilot in an NWA uniform after April, 2009. You won't be able to.

Try scheduling yourself (as a whale guy) using the NWA bid system after next summer. You won't be able to.

Try collecting a paycheck, or buy insurance, or any other benefit through the NWA benefits system January 1, 2010. You won't be able to.

That, and a lot more, happens after DCC but prior to SOC.
