If your customer has been booking JQ and flying on QF, it may be more to do with the HIGH number of JQ cancellations and charters that QF operate on behalf of JQ. I think this week is the first week in 4 that QF hasn't done a charter to HNL for JQ...yet. It's only Tuesday!
As pointed out by a techie recently. Ever noticed that the charters are QF flight numbers & operated as a
QF RPT service per the ATS plan.
