In stitching together a trip in South America I notice the OW timetable doesn't list an 06:50 departure CUZ-LIM. EF and ITA both include it. It's operated by LP, as are all the OW flights on that segment and I don't see any difference between it and the other 8 daily departures. (Yes, I'm asking for the same date (7 Jan 12) in each case.

Downloading the dataset didn't change anything.

My real question is 'is this a common problem?'. Makes the timetable less useful if one has to doubt it.
