first, like dirty said, we don't have an SLI with comair, asa, skywest, chq, etc.
second, sure when you buy a ticket on delta to nrt you may at some point fly on a dci carrier or the oversized dci carrier known as alaska, but that's all a part of the scope arrangement.
i don't see how this passes the test. The PWA defines an air carrier as: a citizen of the United States undertaking by any means, directly or indirectly, to provide air transportation.
I see both the Midwest flying on the E190s and the Frontier flying on E190s and A319s is in violation of 1.D.2.
RAH has has the power or right to manage or direct the management of all or substantially all of the other carriers operations, that's control according to section 1. Their pilots are all on 1 list, how that's not operating in essence as a single carrier is beyond me.
All of this started when CHQ got caught by APA back in 03 or 04.
APA needs to step back in and do something about it,
for the sake of Delta pilots.
