My busiest flying day had 8 flights, and I have a couple with 7 and lots with 6 flights. My busiest flying year had over 400 flights.

So not much surprise my lifetime average flight every x days is comfortably in the black category. BA97 only has my flights since I joined FT (less than 6 years ago) - in that time (and excluding the future flights I have entered into BA97) I have averaged a flight every 37 hours (yes hours not days).
