I can't say I've come across this before, but I'm assuming someone else has. I'm doing some research on a roundtrip ticket from Las Vegas to Dublin later this year. ITA shows that Finnair will sell me the return flight (as part of a roundtrip fare) for about $1300 less than BA will as a codeshare on a BA flight. I thought it was an anomaly that would resolve itself one way or the other but it's been that way for about a week. Anyone have insight on whether this is just a fluke or a pricing strategy? I can't imagine BA wants someone in their strategic alliance underselling them on BA metal, nor would I think there's $1,300 cushion in what the two might ultimately agree to sell the same seat for.
