So I understood that to fly into or though class c you just need to be two way comms with the controlling agency. In the CAT 7 you are asked to fly though a Class C on your way to a class D beyond the other side.

My question is that in the communications example on this page https://www.pilotedge.net/pages/cat-07-rating it gives the request example as "SOCAL Approach, Cessna 123AB, 15 miles east of Ontario, level 4500, request Ontario class C transition, destination El Monte.”

Couldnt this be reduced to "SOCAL Approach, Cessna 123AB, 15 miles east of Ontario, level 4500, destination El Monte.”

(assume the controller replies with your call sign in either case)

Is that correct / what did I miss.

thank you.

As no one replied I will assume the reduced form is indeed perfectly fit for purpose.

You still need to make some form of request. "Destination El Monte" isn't clear if you're asking for advisories or just transition of the Charlie. If you're asking for advisories they'll give you a code and keep you until you're talking to EMT tower. If you're just asking for the transition, they'll give you a code, pass you to ONT tower, and then ONT will drop you. It's good to have efficient radio calls, but in this case one does need to be explicit about the request.
