I passed through Tokyo Narita yesterday, arriving ontime on NW28 from Bangkok. We pulled into gate 46, which is part of the new extension at the end of Satellite 3 (where United typically is). It was a long but refreshing walk into Security at Terminal 1. I noted that NW planes were very scattered among Satellites 1,2,and 4. Are they reducing/eliminating the need for bus gates now at NRT? I didn't think at the time to see if they were scheduling NW departures out of Satellite 4 (which is far-removed from NW operations and World Clubs) at NRT. Anyone know what's up?
