Hmm yeah, how do I get in Lunatic Pandora at Tears Point?

Fly into the flying box, using the ragnarok, if you have it, but first go to Edea's house and into the garden, Rinoa will appear, and after the promise scene you'l receive a message that Esthar president is calling you, after talking to him, you can enter the Pandora

Well, I already spoke with Rinoa at Edea's and had the talk with Laguna at Esthar. BUT, I can't fly into the Lunatic Pandora. Any reason why?

Hmm....uh did you talk to laguna in the ragnarok? Did you have been briefed, it's not entering the Tears Points, is flying right into The Pandora

Only the kids are on the Ragnarok :/

Did you go to the room where are a bunch of seats?

Yeah, I searched the whole place.

Huh, have you been briefed by Odine when you're talking with Laguna?

Okay, I backtracked to Laguna's office and it turns out I didn't accept the mission. Stupid mistake by me, thanks for your help though!!

U should have done that anyway case settled.
