The $46K is my deposit, and correct, there is a sliding scale bond. SIA pursue bond- breakers with tenacious zeal all over the globe, by the way.
I had 500 hrs A330 before coming, but 9000 command total. Many people come with no heavy time, but since this airline only has heavies, they don't make the big drama associated with others with mixed fleets.
Just back from 3 days in San Fran. Very pleasant!
