Narrative:

Leveled off at FL220 during climb out, warned by ATC to check altimeter, forgot to set 29.92, had 29.77 set. Traffic within approximately 5 mi with 800 ft vertical separation, the traffic at FL230. Just forgot to set 29.92 passing FL180. No excuses, just missed it. I've done it so often (set 29.92), got complacent. Callback conversation with reporter revealed the following information: the reporter flies the B-737-200 for a major united states air carrier. He has not heard from the FAA on this incident. He is properly contrite.
