I think it's a moot point, since NMB isn't going to release you to self-help. APFA is last in line behind the pilots and TWU. Strike threats are just that - threats. Bluffs, even. All you're doing is scaring away revenue from the company. Not exactly productive to the cause of getting a raise.
There is no timeline and all the parties are at the same point in the flowchart. Who goes first is anyones bet, they could release us all on the same day. If the mediator sitting on the FAs case decides that talks arent going anywhere he could release them today. Thats when the clock starts and real negotiations begin, without a ticking clock the company has no reason to negotiate.
As far as scaring away the revenue, where are they going to go? There isnt much excess capacity in the system.
