I just booked a flight that goes on a few UA/TG/NH flights, here to Asia is in business while return is in economy. As I was looking at it, I see that the return trip is only allocated one checked bag for free. The 2n bag is $70 per segment (since I connect in Japan this 2nd bag will be $140) per person. That to me is really strange as almost all intl flights I've been on allow 2 bags per person. But it appears doing award travel in eco they only allow one? Is this true? Or simply the rules have changed.
