Narrative:
Our cruise segment was in conditions that resembled 'clear and a million' -- the first officer had spent a short night in a flea bag hotel after fighting the commute. So I offered to fly the 'long ones' -- our plan ewr to lax via msy and sat. Just prior to touchdown a flight attendant plopped down in the cockpit to chat. I didn't object because it was a welcome diversion and I thought we needed the stimulation -- here: I was flying -- I took the radio call from ATC - - wrote on my note pad 50/280 programmed the down track fix dialed in the new altitude and the 'machine' throttled back and pushed over, approaching FL260 my own personal alarm went off. I'd programmed 240 into the box, called ATC and 'fessed up.' she (ATC) said, 'no sweat. Pilot's discretion to 240.' spent rest of flight (and day) reviewing events. Have decided crew fatigue is the devil here! (With no help in sight!)
