All,

Without getting into too much details of why I need to know what a full fare is, I currently have an issue in finding the true definition of a full fare. What I'd like with this thread is to anwer the following questions:

1) Is there a legal or official definition of full fare? If so, can you provide the link to it?

2) From what I understand, a full fare, is a non-discounted fare, with no penalties, fully refundable. With that said, a round-trip full fare ticket would cost exactly double as a full fare one-way ticket to the same destination. Is that a correct statement?

3) In my view, if a fare that is claimed to be a full fare, costs less than double its equivalent one-way full fare, it has a built-in discount and it is hence not a full fare anymore. Is that a correct statement?

I'd enormously appreciate any help I can get on this.
Thanks!
