Narrative:
While en route to sequ airport we received a TCAS RA approximately 60 mi north of the qit VOR on UG426. The alert was to climb. When we noticed that the aircraft was continuing to climb with us we started a right turn. We achieved an altitude of just over FL370 when the alert stopped and were to the west of the airway. After contacting ATC and the alert stopped we assumed a heading to rejoin the airway. The TCAS showed the other aircraft to come within 600 ft of our aircraft.
