So I suppose for a DM with significant J/F travel:
* At 1200 TP, he/she will requalify DM.
* At 1400 TP, he/she will get two J/F lounge passes.
* At 1600 TP, he/she will get four bookable upgrades, but get to keep the two J/F lounge passes.
* At 1800 TP, he/she can nominate a GO member, plus keeping the four bookable upgrades and two J/F lounge passes.
Is that correct? If not, he/she may as well use the lounge passes before getting to 1600 TP so CX won't take them away, and use the upgrades before nominating a GO friend.
