最近想开个台日+日本国内线里程票
行程类似：
TSA (松山) - HND (羽田)
(开口)
NGO (名古屋 中部) - CTS (新千岁)
(转机)
CTS (新千岁) - ITM (大阪伊丹)
(停留)
ITM (大阪伊丹) - FUK (福冈)
(转机)
FUK (福冈) - HND (羽田)
(转机)
HND (羽田) - TSA (松山)
已经确认符合规则，日期如果选明年三月可以开出来。
但是如果把日期换到八月，选完第一段后按next，之后的国内线常会直接跳出：
There were no flights that could be combined. Due to the reasons below, your
flight criteria must be amended.
・There are no flights with seat availability on your specified sector, or
there are no award seats available.
・You have selected the waitlisting option but the flight includes a sector
not operated by ANA.
我想应该是还没放票? (如果在售票系统选一样的日期可以买票，所以航班应该确定了?)
请问各位前辈，日本国内线大约多久之前会放票?
或是这样的情形有办法直接请客服开票吗?
谢谢！
