A few winters ago over Missouri:
Center:
“Delta 246, climb and maintain FL350. Traffic three o’clock, 20 miles at FL310.”
Delta 246:
“Roger. Delta 246 departing FL310 for FL350. We see traffic at our nine o’clock position, level.”
Center:
“Ahh – roger, Delta 246. That was three o’clock Zulu, nine o’clock local.”
Delta 246:
“Nice recovery, Center. In sight off our left wing. We’re climbing to FL350.”
