Narrative:
The first officer responded to a TCASII RA 15 mi west of pxr while cruising at FL290. An aircraft was climbing rapidly wbound toward us and caused the TCASII RA warning. In accordance with FARS and company procedures, the first officer disconnected the autoplt and smoothly climbed at a rate of 1200 FPM (TCASII green arc on vsi) to FL295. After the clear of conflict message was received from the TCASII, we descended to FL290. The lower aircraft was cleared by 1000 ft. The problem seems to have been that we climbed within 1500 ft of an aircraft cruising above us at FL310. Supplemental information from acn 356544: TCASII indicated TA from aircraft climbing at 10 O'clock position. Contacted abq at their request at termination of flight leg at jfk at approximately XA20Z.

Title: POTENTIAL CONFLICT LTSS BY AN ACR HVT WITH 2 OTHER ACFT, 1 IN CRUISE FLT ABOVE AND 1 CLBING TFC TOWARDS OCCUPIED ALT. AIRLINE OPERATIONAL PROC EVASIVE ACTION CLB.
Narrative: THE FO RESPONDED TO A TCASII RA 15 MI W OF PXR WHILE CRUISING AT FL290. AN ACFT WAS CLBING RAPIDLY WBOUND TOWARD US AND CAUSED THE TCASII RA WARNING. IN ACCORDANCE WITH FARS AND COMPANY PROCS, THE FO DISCONNECTED THE AUTOPLT AND SMOOTHLY CLBED AT A RATE OF 1200 FPM (TCASII GREEN ARC ON VSI) TO FL295. AFTER THE CLR OF CONFLICT MESSAGE WAS RECEIVED FROM THE TCASII, WE DSNDED TO FL290. THE LOWER ACFT WAS CLRED BY 1000 FT. THE PROB SEEMS TO HAVE BEEN THAT WE CLBED WITHIN 1500 FT OF AN ACFT CRUISING ABOVE US AT FL310. SUPPLEMENTAL INFO FROM ACN 356544: TCASII INDICATED TA FROM ACFT CLBING AT 10 O'CLOCK POS. CONTACTED ABQ AT THEIR REQUEST AT TERMINATION OF FLT LEG AT JFK AT APPROX XA20Z.
