Becuase of low demand to Japan, CX524 is canceled until 31st May.
So, if this low demand continues, there is a chance of cancelation of CX524 at September.

Bye the way, landing at NRT before 600am is prohibited.
So, actual departing time of CX524 is fluctuated by weather condition etc.
In my last CX524, it departed around 200am. After gate closed, we had to waited for almost one hour.
