Assuming IAH falls in the 4001-5500 miles bracket and off peak, it should be 62.500 for C one way and 85.000 for F. Difference is 22.500. With a 50 % discount 11.250 (12.500 for peak)
Or is the 45.000 for the return flight as well? (for 2)
I called up just to have a sense check and it's actually right. I was charged 45000 for 2x return flight upgraded so 22500 x 2.
