Actually, I don't know that myself.
I realize that the program preferences depends on the travel habits, but my point was, I'm not really into flying OW if I don't have to (not because I think OW is bad or anything, but *A has already its claws on me...

). So 9 out of 10 flights I cover with *A and Sky, but there are that occational 10th time I have to take OW flights because of price or time beyond my control. And mostly, I pay for my trips myself so we are talking about economy fares here...
Obviously, I'm not aiming for a tier status here. But rephrasing my question, which OW frequent flyer program is least bad for the in fact not so frequent OW flyer? Again, I know there might not be a clear answer to this, but based on some opinions here, I'm hoping to get a free flight in 5 years instead of 10, if you know what I mean. And I expect to travel quite globally the comming years (ok, mostly in Europe and North America).
And of course, it's also a matter of which program has a good coverage, so that I accidentaly don't let the miles expire or something just because I'm stationed somewhere out of its reach...
