And today's AY102 was the final flight of the year (BTW an excellent flight which was super empty and guaranteed a very nice service in J!), so the statistics are in:

Total flights: 259, of which domestic 92.
Total mileage flown: 171 264
Carriers: 52 (no way I'm going to list them)
Airports: 82 (top 3: HEL, OUL, ARN)
Countries: 29

This was my best ever flying year, mostly because of the Lumo madness - 2017 I had 240 segments so managed to even improve on that.
