You want to be punctual just extend the journey time.
To be on time just have a journey time of 1 hour 20 mins instead of 55 mins. That way you’ll nearly always arrive early and exceed expectations of the passenger. If you’re late you give a bigger buffer to avoid compensation,
Still what a fantastic success this company is. Wish I had those ideas but I didn’t and that’s why he’s brilliant and I’m slogging through life making ends meet and availing of cheap flights so congratulations to him.
