Air China, 0-2 days (several flights ranging from interconentinal to intra-china and mainland-HK).

I found it funny that one of the domestic segments within China (CKG-PEK) was posted immediately after the longer segment (PEK-ATH) was flown, approximately 17 hours from the CKG-PEK departure. Might have had something to do with the journey being a day-1 10PM flight into Beijing and day-2 2AM flight towards Europe. Overall positively surprised by the posting time on CA
