Narrative:

On arrival into sna; original routing kept us clear of lax class B airspace until close to shoreline. Approach control vectored us off of planned route; resulting in flying under lax airspace earlier than planned. Not sure where limits of class B airspace were; we began slowing; just as approach control informed us that we were 'operating under the los angeles class B airspace.' we continued to slow; nothing else was said.
