Nope, the plan is to interfly between the certificates. One day flying a Polar flight, next day a Giant flight.
Can't be done, unless I missed something in the regs....Unless they can figure a way around 121, the 8400.10, and PRIA/Drug Testing, it will only remain a way to give hope to the "merger". Unless there is some exemption that I don't know about. I'm not sure how (if) CAL works it that way. I know no other "holding company" with subsidiaries does it that way, even the ones with "ONE list".
Maybe someone from CAL could let us in on if they DH from IAH to fly micronesia....
