They offered VJM the entire summer of 2011. I don't see how this summer will be any different. But they have other tools to use and nothing will surprise me.

"CAL Part 5 - Vacations General
A. When unforeseen circumstances create an operational need, that is, an event severely limiting the availability of pilots in a Base, Equipment and Status, a pilot's vacation may be canceled. Before a pilot's vacation may be canceled, Pilot Manpower Planning will ask for volunteers who are willing to change their vacation. If there are not enough volunteers, then pilot vacations will be canceled in reverse order of seniority. A pilot will be given at least thirty (30) days advance notice of a vacation cancellation unless he agrees to a shorter notice."
