Reserve gurus:

I have a question about domestic duty limits on reserve.

Let's say you fly a trip an over night trip and return the next morning. Your local showtime for the return leg home was 6AM (Elvis time). You arrive at 10AM.

Being a B reserve, you are assigned a trip that afternoon when you arrive. It is the same footprint, an afternoon launch, layover, next morning return.

My question is this: Are we limited to a 13 hour duty day (CBA scheduled limit) or some other limit when we are being hub turned?

I said 13 and I was told by a "reserve pro" that as a reserve, we were always good for a FAR max day. Say it isn't so, it will cost me a beer...
