Upgraded early this morning, from ET to CE, on a short flight and around two weeks ago, from WT to WT+ on a mid length flight. Those for the first upgrades for a very long time. Short flights at the back of the bus don't bother me at all and on any route that is served by QR, I now chose QR and am generally already in QR J, so it makes sense that BA upgrades are now sparser than there were in days of old during which I tended to be on more longer BA flights more frequently.
