Beedle's Airshop

Beedle's Air Shop, as its name suggests, is a shop run by Beedle in Spirit Tracks and in Skyward Sword.

Spirit Tracks
In Spirit Tracks, the shop is operated in a hot-air balloon and opens after Link completes the Snow Temple, at which point the young hero will receive a letter from Beedle inviting him to visit his store. Beedle's current location is marked in the overworld's Rail Map.

As Link is traveling around the four realms, he can get Beedle's attention by blowing the Spirit Train's whistle when his hot-air balloon is nearby. He will land by the Spirit Tracks, allowing the young hero to stop by it to visit his shop. Similarly to the Beedle's Shop Ship, Beedle offers Link a membership at his shop after he buys his first item. The membership allows Link to save up 2 points for every Rupee he spends in the store, which lends itself to certain rewards (including membership upgrades) after Link passes point milestones. After the young hero obtains the Silver Membership, he will be rewarded with a Freebie Card, which will allow him to obtain any item from his shop for free, although no points will be gathered if this card is used. Accumulating 500 points will reward Link with the Gold Membership along with a Heart Container for being such a frequent shopper.

Beedle's Air Shop is the only place where Link can buy a Bomb Bag, which is set a price of 500 Rupees. Other than this, Beedle also offers Red and Purple Potions as well as bombs and a variety of treasures. Unlike other shops in Hyrule, treasures can only be bought once, meaning that Link will have to wait a day before Beedle restocks.

The point requirements for the shop's membership card levels are as follows:

Skyward Sword
Beedle's Air Shop makes a return in Skyward Sword. Beedle has to pedal to keep his shop aloft and will release a trap door on Link out if he fails to buy anything, causing him to fall to the ground. He sells the following
 * Life Medal (800) - Adds a single Heart Container to your life bar if in the Adventure Pouch.
 * Extra Wallet (x2, return later) (100) - Carry another 300 Rupees
 * Bug Net (50) - Catch bugs
 * Adventure Pouch Upgrade (300) - First upgrade
 * Adventure Pouch Upgrade (600) - Second upgrade
 * Adventure Pouch Upgrade (1200) - Third upgrade
 * Bug Medal (1,000) - Shows bug locations on the map.
 * Piece of Heart (1600)
