Why are there so few bonus tickets TO Denmark, while tickets FROM Denmark show up fairly often?

Tiltle says it all

 

Very good question. I have been wondering that myself many times. Especially business tickets from the West Coast seem very hard to come by. I understand that it is a sought after way for Americans with their many miles from credit cards to travel to Europe. But don't they also have to go back again? What do they book on the way back?

 

1. The demand is unfortunately not it - the supply of tickets is simply a lot less - you can see of BKK tickets: many there, almost non back

 

And the issue is once you have booked one way and you can find a return, than you almost pay the same price when buying a one way ticket back vs. A fully paid return ticket
