Airship/Hidden Aeons

I’m really confussed couse, couse every walkthrough i read it says use the airship to get to the temples and to get Rikku’s Legendery Weapon you have to input a code, in the airship or something,

put how do you do that,

i’m in Calm lands now but i saved for backup at Home, if i forgot something,

someone help me couse i want all the Aeons
And wherer is the best place to Gain most EXP.

The Airship is supposed to be damaged,you’ll get it back after Zanarkand,after you beat Yunslesca,and exp. I would say the Omega Dungeon,even though some of the Trainer’s monsters give more,the battles are faster and easier in the Dungeon.

Thx for clearing that up for me, i was really confused back there.

and i’ll try to locate The Dungon,

Make sure you’ve got all six of the destruction sphere treasures (Besaid, Kilika, Djose, Macalania, Bevelle and Zanarkand). If you’ve got the international version, it can be a sod to get back into Macalania and Besaid (damn those dark aeons), and if you forgot those two, then you can’t get Anima or the Magus Sisters.
