汉莎LH728选不了座位?已解决,打给客服成功选座。

Hello,我订了 LH9053 + LH728。
LH9053在UA选座位很轻松,但是LH728就一直选不了,提示
Seat selection is currently not possible since the advance booking deadline of 52 hours has been exceeded. It is possible to reserve your seat free of charge during online check-in, 23 hours before departure of your flight.

有人遇到过这个情况吗?这个看起来是说应该提前52小时才能选座位,但是我这个还有超过5天啊。。。为啥不能定呢

更新一下。。。今天打电话给北美客服,交费选了座位~
