Hello

I have two separate schedules.

1st flight as follows:
2019.01.19. 23:50 - 01:40 (+1). ZE 821 (CJJ > PVG)
2019.01.31. 02:50 - 05:40 ZE822 (PVG > CJJ)

and between this flight, i'll book a more flight as follows,


2nd flight as follows:
2019.01.21. 22:45 - 06:05 (+1) MU8156 (PVG > MRU)
2019.01.29. 22:30 - 13:55 (+1) MU8155 (MRU > PVG)
