Actually, QF DOES codeshare on LGA-YUL-ORD-HNL. Other unlikely QF codeshares include LGA-YYZ, ORD-YOW, etc.

From the examples listed on bestflights, it looks like ALL QF codeshares are eligible for this fare, e.g. the routings through PPT and NAN. Agree that this could be quite a lot better than LONE4, especially for all those who consistently try including Fiji on xONEx products. What's the catch, though? Are there any sector/transfer/mileage limitations for this routing? And what constitutes a stop? For example could this fare be (ab)used for a multi-sector MR within Europe on IB/AY/EI/BA with each connection under 24 hours?
