[QUOTE=DelDah Capt;1196595]if mainline block hours fall, DCI hours would have to fall./QUOTE]

While that is definately some level of protection while the company is still in the process of growing the additional aircraft in the ultra large DCI 90 seater fleet (with 76 seats installed with a generous first class) once they get all 223/325 if they pull mainline back, how exactly are we going to enforce it?

How will we make them honor our contract by making them break other contracts when supposedly they can't get out of 50 seater contracts because they can't break RJ contracts unless they replace them with equal or more lucrative RJ contracts?

Is this even enforceable in real life?
