All though PK-GIF and PK-GIG (the 2 B77Ws with First cabin) have been used consistently on the DPS-NRT recently the First option cannot be selected for a booking on a random date (don't know how to post smaller thunbnail images). I would have thought First would sell on this holiday destination route for weathly Japanese tourists, but I'm not an expert in this subject. First is only available CGK-LHR 3x per week.
