Realized that now. That sucks.
It does if you want all in J or F but actually to have 2 seats on every flight is pretty good and they have such good J and F availability from the US-HKG. I'm still planning to book this way because with Dan's new hiddush of transferring SPG to Virgin and then to Alaska, I can get from Den-TLV, with the Shabbos stopover in HKG for only 38k SPG...at that price, my kids can sit in Premium economy for the last leg!
