SK1594 takes me from where I work and live to where I come from. I love that flight for a lot of reasons;
I've made money a few times, voluntarily off-loading for cash. When I do make the flight, I'm as good as always upgraded to C from cheapest Y. It takes me home.
Don't if SAS likes it, but it's certainly my favourite
PS
Easy way to make money: Book a thursday departure well in advance. On that flight everybody booked + a few more on flexible tickets nearly always show up. Usual mayhem ensues, make sure you're close to the gate counter and stand ready to flap arms and scream "
ME" when the call goes out for someone to take the next flight.
