Air miles good for absolutely nothing

I’M FLYING out to Bengaluru this weekend, so thought I would try and use my Virgin miles to make things a little easier.
Fat chance. Spending the miles I’ve got is not easy. The airlines seem to have got themselves into a total spin and have forgotten that the purpose of these schemes is to keep customers loyal. Not frustrate us.
Far as I can see, to spend some of these miles the easiest thing to do is call the Virgin people and get hundreds of vouchers for Virgin wine – which I don’t really want.
There’s probably some kind of rule that prevents you doing that as well. What’s the point of accumulating miles if the airlines put every difficulty in your way in spending them?
