Icare about your questions
1.- Base just Singapore , no time for commuting if you go America or Europe and you have to pay a ticket,........ discount? yes but is almost the same price as full fare and subload.
2.- Fast upgrade?, at least 3 years and then move to local term and get into the pool. (think about 5 years)
3.- Bond? Same as everybody 23k
