Last year was somewhat busy with a total of 53 flights (3 AY all econ, 2 LH both econ, 3 AA 8 econ, 5 econ+, 35 BA 8 ET, 5 CE, 9 WT, 10 WT+, 3 CW ) amounting to 126,796 air miles (or 132,631 actual miles) - 255.4 hours in the air.
This year a lot less - although I tend to plan a year out, quite a few flights get slotted in at the last minute (my record last year was a TATL booking 3 hours before the flight...).
