Yes! You may gift the Journey pack to friends playing on other devices. However, please read the details below so you purchase the pack from the appropriate shop.
 
Purchasing the Journey pack from the in-game shop allows you to purchase the Journey pack to give as a gift to friends  using the in-game gifting feature within their friendship tree.
 
Purchasing the Journey pack from the PlayStation Web Store will automatically attach the pack to your own Sky account if you do not currently own the Journey pack. You will need to purchase the item pack again to receive a giftable consumable that you may send to a friend using the in-game gifting feature within their friendship tree.
 
Purchases made from the PlayStation Store website on a PC or web browser will be inaccessible until the game is launched from a PlayStation Console. Once the game has been launched from your PlayStation, your purchases will become available.
