Every company had a different deadline. TSA, Mesa and Chatauqua had theirs in on the 28th of April, I believe. AWAC submitted theirs on the 5th of May and ACA was due yesterday, I think. ACA and AWAC both asked for and recieved extensions, because they had to renegotiate all of their labor contracts in order to be competetive with the bottom feeders of the industry.
Not too sure about Skywest.
Once a boulder is pushed down the hill, its is not going to stop until it reaches the bottom.
Mayday.
