I am told (IANAL) that in some jurisdictions, California has been mentioned, it is illegal (in the precise sense of that word) to use a ticket for transportation in violation of its terms and conditions. To the extent that this practice violates the CoC (which states the terms and conditions of the ticket), and to the extent that my information is correct, then it is indeed illegal.
