Option 2 won't be an option.
Indigo has already been through a strike. They realize there won't be enough scabs to continue on as a viable entity. They also realize the flying won't be picked up by charter companies, nobody picked it up for them during the Spirit strike. They also know how much the strike cost them. They also know what impact it had on pax loads going forward after the strike, which was minimal.

Option 3
We continue negotiating in good faith. Get realesed. Enter the cooling off period. A couple hours before the strike a TA will come out.
Pay will not be Delta plus anything. It will be industry average for the aircraft we fly. That's what our union is negotiating for, industry average. That's the only way the mediator will release us.

Also keep in mind a 75 hour guarantee is not industry average either. Look for the company to come to the table with lessor guarantees, perhaps one for reserve and one for line holders, similar to the industry average.

PBS is also industry average or standard. This is a major sticking point at Spirit right now with their new CBA. Apparently Indigo isn't asking for it here at F9.

This is a MEDIATED negotiation, don't expect to sit at the table with industry standard demands and not be asked for the same in return.

On a side note. The company did offer $224 for max captain pay year two of the contract in their proposal. That's close to or at industry average. That number being their initial pay offer I feel there's room to negotiate more on pay. Unfortunately the rest of the proposal was sub standard.
