The convention is slated to start Monday.

MINNEAPOLIS, Minnesota (CNN) - The McCain campaign has arranged a charter flight from Minneapolis-St. Paul to Jackson, Mississippi, on Sunday afternoon for delegates who wish to return to the Gulf Coast region ahead of Hurricane Gustav, CNN has learned.

Louisiana Republican State Party Chair Roger Villere Jr. tells CNN some Louisiana delegates have already departed while others plan to leave, though he could not give exact numbers.

The same plane will fly back to Minnesota if delegates have children or other family members they want to remove from the area.

“The McCain campaign has been extremely helpful," Villere said.
