The flight to OGG does require using perk pass (10K) to get "my ideal time" but the return only requires perk saver (5K) and is my ideal time to boot.

I can't seem to get it to let me book one way on the 5K however. Have to do the whole RT. Anyway around that? If not, I think I'll just buy the tiks. 15K each seems a bit steep for a $160ish RT tik.
