We are attempting to book our annual trip from Toronto YYZ to Kona Hawaii KOA via Aeroplan. Travel dates are March 17/2015 and return May 1, 2015. I've attempted to be flexible on dates but there seems to be ZERO availability between March 4 and April 17 (looking for economy). Although it's a distant second preference, I've also tried Toronto/Honolulu with no better luck. Does anyone know if there is some type of extended blackout being applied for travel to the Hawaiian Islands during that period?

I just got off the phone with an Aeroplan Agent and she was unable to offer any help. This is the first year we've had this significant an issue.
