"Airborne craft, developed by the moogles centuries ago. They float by the power of skystone, and are given direction and speed by means of propeller or glossair ring. Currently, they are one of the most popular forms of transport in Ivalice, and the skyroutes are comfortably the busiest of the highways linking the major cities. Airships range in size from private yachts to giant military warcraft. Unable to fly in jagd, where skystone is ineffective."
Skyferries(飛空艇定期便 {ひくうていていきびん},Hikuuteiteikibin?) are used as transportation in Final Fantasy XII. When riding Skyferries, the player may choose to sleep on the flight via the Private Cabin option or explore the airship via the Leisure Craft option.
Players need to talk to six sisters that work as Chief Stewards aboard the leisure craft airships that connect the largest cities of Ivalice. If the player fails to complete the quest, the six sisters will be forced into an arranged marriage.
To start the quest, the player should take the Bhujerba/Rabanastre flight via leisure craft in the Aerodrome and talk to Ann, the Chief Steward at the Sky Saloon. Agreeing to help her begins the sidequest, which will can only be completed after visiting the Port at Balfonheim.
The player must ride all the Skyferry routes and talk to all the sisters to deliver the letter. After completing the quest the player will get the Ring of Renewal for their troubles.
There are no treasures to be found on the Skyferries in the original version of Final Fantasy XII, but the Final Fantasy XII International Zodiac Job System, a Japan-exclusive re-release, adds a super secret invisible treasure chest that can be found randomly on the float deck of an airship. It appears 1% of the time, and contains a Seitengrad (a new ultimate bow added to the game) 0.01% of the time. The treasure is invisible, so the player will only find it if they bump into it. If the player acquires the Seitengrad an arrow will appear in the sky in the Cerobi Steppe suspended a few feet in the air.
