The Tumbler Sparrow offer expired at 1 am pacific time on January 15th, 2015.
From your game history, it looks like you took a break between October and mid January. In guessing you purchased the expansion pass around the January 15th deadline.
Obtaining the sparrow required both purchasing the first expansion, and logging into the game with it, by the deadline.
If you and your friend purchased on the same day, and that was January 15th, it's possible that he purchased in time and you did not, or that you purchased the expansion before the deadline but did not log in with it until after the deadline.
