Interesting thoughts... I felt it was odd and maybe related to the grounding of all 787 flights (LOT Airlines seemed to be the only way to get J seats to North America in August)
zlc: I'm looking at early August, not the end - so we're not competing
I ended up connecting through Warsaw to and from Europe, although I'll keep my eye open on availability.
By the way, if you could choose for J: OS, LO, LH, or LX - and in what order?
