I have travelled quite a lot, somewhere north of 1000 flights. Many were simple round trips, but not all. Probably the craziest took me from Australia to the UK, via five other countries, over seven days, using 9 airports.
Day 1: Brisbane to Singapore on SQ (home at the time)
Day 2: Singapore to Jakarta, and return, on SQ for a meeting
Day 3: at home, doing washing and repacking
Day 4: Singapore to Tokyo on SQ
Day 5: meeting in Tokyo, then ANA to Shanghai
Day 6: meeting in Shanghai, then KLM to Amsterdam
Day 7: meeting in Rotterdam, then KLM to Gatwick
Technically this was the back end of one trip SIN-SYD-BNE-SIN, a standalone visit to Jakarta, and then the first part of another SIN-NRT-SHA/PVG-AMS/RTM-LGW/LHR-SIN. By the time I got back to Singapore I had flown around the world because the PVG-AMS leg had flown east and crossed the international dateline.
What's your craziest trip?
