From mid Feb to the end of the winter season (late April)...
AC increasing Hawaii to a three daily operation.
YVR-HNL from 7 to 9 weekly
YVR-OGG from 7 to 10 weekly
YVR-KOA from 1 to 2 weekly
Effectively rouge is adding a daily morning service to Hawaii (spread across the three destinations) in addition to the twin departures in the late afternoon.
That's almost 2,000 additional seats per week to Hawaii.
Along with Westjet, this will bring total YVR-Hawaii services to 62 flights per week. About 9 flights per day.
With the above... Plus... Aeromexico's new daily service, AC re-launching CUN, WS launching MCO, plus all of Sunwing and Air Transat's new offerings... there will be plenty of additional sun-seeker seats being offered from YVR this winter.
