Just returned from a pleasant weekend in AMS. Ms astralclouds and myself were on separate bookings - she booked an el-cheapo Y, I was outbound in J (corporate return leg) and on a one-way in Y for the return.

Point is, with no obvious connection between our bookings, BA very kindly op-upped us to adjacent seats in CE. We knew something was up when SSCI showed that we could not change our seats. But curious to know what data they use to ascertain that we are travelling together?
