Again I say look at a domestic bid sheet especially those out of DFW, STL and ORD...I think you will see many legs that exceed 8 hours, especially turns. DFW-SEA. ( You are correct its not a single leg, but the duty days match or in some cases exceed those of international ) Not to mention, duty days scheduled over 12 hrs and 3-4 legs a day on a S-80..I personally like flying them because they are high time , but crew rest is non-existent especially on the 80. STL-SAN-DFW-STL is another one I can think of.
