Open time is only updated twice a day. It is impossible to know where your trade stands in the stack of trades, unless you call and ask. You have to catch open time before the 48 hour mark. At that point it goes to a reserve. And no, you don't get paid for it if it goes to a reserve. Why would you? You only get paid for it if they assign it to you.
There are actually a lot of ways trip trades can get denied... like overnight coverage, 29/7, base rest, duty day etc... While it's frustrating, I wouldn't exactly turn on the attitude with scheduling.
On another note... pulling reserve does drag. But watch out who you complain to. There are tons of FOs that did YEARS of reserve and are only now getting to enjoy what it's like to hold a line be it an FO line or finally a Captain line. New hires holding a line after only a couple months on reserve is a new concept at XJ.
