〉本来新加坡上海航线就不是它的主要航线,虽然价格相对便宜,但是时有时无,完全决定于印尼航空公司愿意或者是不愿意
This is Scheduled Flights, which means it is rather fixed in terns of frequency and flight time.
>一般航空公司的固定航线每年的各个季度都会有不同的定价,一般是在季节前2-3个月左右出来
Different Airlines Difference policy. Some airlines adjust the price very frequently while others keep the price at certain level for long time. The Travel Agency will only be notified by fax only there is a change in price level.
>但是像印尼航空新加坡上海这样的不确定航线,就不一定了,运气好,价钱很早就出来了,机票定得也快;运气差到,加价就算了,而且还不一定拿到位子。
You can always book the seat through travel agency but they may not be able to quote the price for you if the price is not released by airlines.
>现在你的情况,估计是旅行社自己也没有拿到印尼航空的报价,所以不敢订票。
This is possible, another possible senanrio is: the seat is not confirmed.
>泰航成都,上海的机票也是一样。
This is bullshit. I traveled by Thai Airways 4 times over about 20,000 miles. IT is surely the budget quality service provider. I enjoy travel with it and most of my friends who have experience with Thai Air are happy with it.

One more issue:
Do not take Garuda Indonisia Flights if transit is needed in Jarkata Airport. IT IS NOT A SAFE PLACE! this year got bomb...
