Not sure this warrants a new thread, but OV just announced you can use OT's empty seat option. It's 1 EUR service fee and 4 EUR for the empty seat:

I typically fly OV on the CPH-TLL route which is about 1.5 hours. I'm not sure I'd make use of this offer, since the flight is short and I don't mind the current seats for that flight.
On the other hand 5 EUR isn't much to pay. I wonder how much OV and OT plan to make out of this. OV probably makes more money selling 2 drinks on the flight than through this.
