The two returns I've used the Ryanair GRO route in the first 5 weeks of ops, I'd estimate 150-160 on each sector.
On a separate note, security has been a shambles recently. Last weekend, the priorty lane was being used by everyone which wasn't going down too well with those who had paid to skip the queue but subsequently had to queue anyway.
On Wednesday morning this week I couldn't purchase fast track because "the machine has no paper". It's 2017 and they lose out on business because there is no paper.
