How do I get to Sanubia Sands using an Airship?

[Crossblades]

I need to go back to Sanubia Sands to get the Mercury Crest for Rikku's Godhand. But I can't get there using an Airship. How do I get there?

Since you are attempting to acquire Godhand, go to Bikanel, NOT Sanubia.

If you still think you still need to go to Sanubia...

You have to use the the Airship's manual location finder. Talk to Cid on the Airship, and it will bring up the Main Airship screen. go to Search Spira (or whatever it's called), and it should bring up a huge map of Spira, with an X and Y axis, NOT the location list.

Go to anywhere between 12-16 (X axis), 57-63 (Y axis), and then Sanubia Sands will be chosen on your locations screen (the one that asks you where to go).

Warning: Sarcasm ahead.

You will be rewarded with Rikku's ultimate weapon once you land. It is in a chest: a giant sword named Ascalon, and bears the Double AP ability. It's so ultimate, that Rikku can't even use it, that she requires Tidus to use it as his own weapon to attack foes with while she is in the party.
