Had a GS question and was debating submitting it to ACE but I know they’re backlogged so figured I’d ask the gurus here first. Got an ARCOS call with 2 rotations in a batch size of 2. One was locked with the message N/O DNO 021 Violation Not Qual Spec Airport. The only airports served were SEA, LAX, LIH, and ONT. The ONT was exit only and it was a deadhead. Looked it up and ONT is only a level one special airport; I’ve used it as an alternate many times. The senior guy took that trip anyway so not due any pay but I’m curious about future trips. Thanks gents.
