If they bought the ticket, then your contract spells out the steps. (not that I'd want another ISL) but, I'd be interested to see how that played out for people who bailed for RAH, got a new hire number there...
Good luck to all, and try not to speculate too much. It won't be right anyways.
You bailing to another airline or getting out altogether? Too bad we never got to fly together. Good luck man.
