I visited Singapore for a few days this october.
The outbound flight was on Swiss, and I could use my miles to get upgraded to business class.
The seat was 7G, second row after the galley. Since I upgraded with miles I couldn’t get a window seat, but having a good sleep in this awesome business class chair is a bit better than a window seat in economy class during a night flight. Therefore I wasn’t that unhappy.
Departure time was 22.45, one of the last flights leaving Zurich.
Flight time was about 12h 15 minutes and I arrived at about 17.00 local time in Singapore.
