Just exactly which niche do you think C3 will try to fill, if they are resurrected? Assuming you mean back to the charter biz, forever forgetting about the sched market, that would be a tough road to travel.
If (a really big IF) they could get the ball rolling again, by the time they do, the business from their major tour operators will be long gone to another carrier. Word on the street is that Skyservice and Air Transat are in competition to win the hearts of Signature, Conquest and the others, with SSV on the inside track, mostly because they don't own any tour operators themselves, and therefore not directly in competition with the tour operators.
Time will tell. Hope whomever wins the business will find some room for at least some ex-C3rs. They're good and loyal folks who deserve better than they got last week.
