So for those posting data points, it would be really helpful to include the airports involved and the direction of travel for any dates quoted.
Thanks

As with IB/BA peak/off peak calendars, Qatar bases it's dates on their anticipated demand for air travel.
The permutations for airports and/or direction of travel would run in to thousands.
There might be slight variations but I looked at some example routes and the dates I quoted seem to tally.
