Well Roz, unfortunately now you are screwed! Once you fly up the pointy end on the plane you can never go back. Every little thing about flying coach will annoy you, and I'm not just talking about the seats!
My husband and I use our points to fly business class long haul. The lie flat seats are as incredible as you can imagine. It is truly a privilege and the gratitude I have when I get the experience each time never passes me by.
But it's so hard to go back to cramped seats and plastic cutlery once you know a better way!
