I'm sure I've seen a wwebsite on here where you can record and keep track of your trips calculating the miles you fly however I've searched and haven't been able to locate.
I use the BA97 calendar (see signature) which apart from tracking ur miles/sectors, has a nifty calendar function which allows you to put up ur upcoming flights/lounge visits and schedule meetings with other people (mainly FTers) if they're on the same flight or in the same lounge at the same time as you are.
The Frequent Flyer Concierge team takes the hard work out of finding reward seat availability. Using their expert knowledge and specialised tools, they'll help you book a great trip that maximises the value for your points.
