Except airships are the only source for getting some of those items to the marketboard unless SE chooses to temporarily insert those items into quick ventures.

Oriental Grass Tuft - airship only.

Dusk Leather - airship only.

Fine Alumen - airship only.

Tincalconite (for the pudding furnishing people love around All Saints) - airship only.

Several other items are airship only but have less demand as well.

If you're solely after making as much gil from voyages as possible, then they aren't worth it. But for those with an interest in the items that are airship only, they're needed.
