Around 3 times a week when in UK/ Europe. When travelling for work or fun, it’s usually slightly fewer flights, but over longer distances. I worked out I put in 25,000 miles and 4 continents over the holiday period (part of that was after me screwing up with something).

I’m still not even halfway to BA lifetime because so many of my flights are in the places which OW can’t scratch.

I have my own consulting business and often have extended periods where I don’t have work/ am not looking which I use to get out a bit.
