I saw this on the website interface only. i noticed they charge more miles for the upgrade than usual. When i booked my business saver KWI/DXB/LHR/DXB/KWI it said 43500 for upgrade to first. When i looked on the website i was offered 11200 the usual from KWI to DXB on Saver however DXB/LHR was 39000!
