(8) Preferred Airlines? Most common Airlines flown on?
Reply:

I have no preferred airline, because of the variety of destinations, I change airline very often.
I have now flights coming up with Finnair to Seoul in J and to Loas Angeles in J with BA, all from Brussels.
I have miles stocked with Qatar Privilege Club as well: 120 Qpoints and 21K miles (from a flight from Brussels to Jakarta in J)
For my next flights i keep using best the Qatar program or should I consider to start using another program from One World?
