Yes, the first time they fly into Singapore.
And of course I hate an FF and a U-TURN on the same leg. Of so many other legs without game specials at all, can't they just split it?
AND, I don't get the FFs anymore. If you're only going to have one per season, give every team a chance to do it immediately after a HoO, or let it be luck based and if a team decides not to try it, they can move on to other tasks but if yes, then they suffer the consequences.
I don't even like the FF anymore. It's just now lame and pointless.
