your knowledge is useful for next good deal. i started learning the details of done last july and august when my sister had one month off in sept and she wanted to bring her infant around the world. i remembered that infant is charged 10% so i suggested that route. we ticketed ex japan. 6500usd. (we ticketed right after yen surged last august and cost me 400 usd more) i used it to finished jal status and aa.exec plat match .

then we liked it and booked 6 done4 and done5 ex jnb. my ticket is cost 4060.

now i ticketed one ex mpm for 3600 in jan 2017

and add one ex mpm for 3000 in july 2017 (5 segments and will pay for routing change to be used to requalify for status in 2018.)
