Expansion Keys are DLC packages for Ace Combat Infinity that allow a player to have more Aircraft Sets than the default four. Each Expansion Key gives players four more Sets. Originally, only four Keys could be purchased for 20 Aircraft Sets; as of the January 2015 update the number of Keys that could be owned was increased to 9, allowing for 40 Sets.
