Despite my previous post, which was accurate when I posted it, I just managed to book August 2015 flights using miles plus money on the exact dates I wanted them. I had to spend £20 on a few extra miles but I've saved £500 + so worth it. My points were going to expire before I used them if I didn't use them this next trip so overall I'm happy. I have had a splurge and gone PE again but had I used my miles for economy seats it would have brought them in for slightly less than Thomas Cook have been quoting for several weeks in this this is useful to anyone.
