The Dutch carrier resumed the route in June with a four-times weekly service on Mondays, Tuesdays, Fridays and Sundays at 5.20pm.
With the further easing of restrictions, the airline now aims to bring the flight time forward to 12.25pm.
From January, it plans to offer twice-daily flights departing Teesside at 6.05am and 10.40am.
Tees Valley mayor Ben Houchen said the route is a "firm favourite" for people across Teesside, Darlington and Hartlepool travelling to Amsterdam.
