Common Sense Note
Parents need to know that Disney's Planes is an adventure that, like Cars, takes place in a world populated by vehicles. A few scenes of peril that place main characters in danger (a terrible storm, a squadron of fighter planes crashing, etc.) may upset younger/more sensitive kids, as may the tension of the big race itself. Because the story is about a crop duster who dares to compete against racing planes, many insults are hurled his way -- like "farm boy," "loser," and "bum," as well as "idiot" and "moron." There's an overt romantic subplot between two secondary characters, including a moonlight serenade and the appearance of lots of kiss marks on the male plane's body. Parents are likely to notice a quick derogatory reference to male planes as "ladies" and a lot of cultural stereotypes in the movie (which warrant a post-viewing check-in with kids). But ultimately the message encourages kids to overcome their limitations.
Sexual
Content
Chupacabra pursues Rochelle, with whom he's fallen in love; after a dramatic serenade, she falls for him, too, and he shows up the next day covered in kiss marks. They touch noses and call each other nicknames. Dusty and Ishani are flirtatiously sweet to each other. A male plane says "look at that propeller" while looking at a female plane's backside.
Violence
A few scenes of peril when it seems like Dusty might crash or die, like when he's caught in a terrible storm and goes underwater, when he flies through a tunnel that a train is approaching head on, or when Ripslinger and his crew injure him. A flashback shows an entire squadron of fighter planes being downed (being shot at, crashing into flames, plunging into the sea).
Language
Insults like "idiot," "moron," "knucklehead," "loser," "punks," "farm boy," "bum," and "go plow yourself."
Social
Behavior
Dusty's journey encourages viewers to not feel limited by their exteriors. Even though he's repeatedly told that he's not up to the task, Dusty works hard to overcome his fears and flaws and compete with the more experienced racing planes. Dusty dreams of doing more than he was built for, and he asks his fans to do the same. Friends are loyal and supportive of each other.
Consumerism
The only brand referred to in the movie itself is Apple; a plane is looking at what is obviously a tablet computer, and he calls it a "SkyPad." But there are lots of off-screen licensing/merchandise tie-ins: clothes, games, apps, and more.

Reference to a fuel enhancer that disqualifies one of the participating planes.
