Items included in the free Rocket Pass include customization items, decryptors, banners and in-game titles https://www.lolga.com.
Those that cough up the dough for the premium Rocket Pass get everything from the free pass along with car bodies, keys, premium banners and premium in-game titles. Premium gamers can also earn XP boosts and XP awards to Rocket League Crates help move through the Rocket Pass faster. A Premium Rocket Pass subscription costs 10 keys, or $9.99. It hasn’t been mentioned how long each Rocket Pass will last, but Psyonix did mention there will be several Rocket Passes per year.
Every item earned through both the free and premium Rocket Pass is tradable, except the items that aren’t normally tradable to begin with like titles. Players that want to jump up from free to premium can at any time, and will be rewarded with all the premium loot he or she would have already unlocked.
