Narrative

IN THE VICINITY OF 30 DEGS W; OVER THE ATLANTIC; WE WERE DEALING WITH A SERIOUSLY ILL PAX. A CARDIOLOGIST ON THE FLT WAS CERTAIN THAT SHE HAD A BLOOD CLOT LODGED IN HER LUNG (PRIOR HISTORY) AND THE SIT WAS GRAVE. AFTER ASSESSING THE LOCATION OF ALL AVAILABLE FACILITIES; WE DETERMINED THAT OUR ORIGINAL DEST; LHR; WOULD HAVE THE BEST MEDICAL FACILITIES AVAILABLE TO HANDLE THE EMER. I WAS THE FLYING FO AND CONTACTED THE HF CTLR IN GANDER; REQUESTING AN INCREASE IN SPD FROM MACH .84 TO MACH .85- .86. THE REQUEST WAS GRANTED AND WE IMMEDIATELY INCREASED OUR SPD. AT THAT TIME; WE WERE ALSO GIVEN PRIORITY HANDLING TO LHR. ALTHOUGH WE HAD NOT REQUESTED AN ALT CHANGE; A CTLR THEN ASKED WHEN WE COULD CLB TO FL390. WE TOLD HIM TO STAND BY WHILE WE CHKED WINDS; WT; ETC. HE THEN REQUESTED US TO 'CLB AND MAINTAIN FL390 WHEN ABLE;' OR SOMETHING CLOSE TO THAT. THE CAPT THEN SET FL390 IN THE ALT BOX; AND I BEGAN THE CLB. AS WE WERE XING 30 DEGS W; THE CAPT GAVE A POS RPT TO SHANWICK; AT WHICH POINT IN TIME SOMEONE CAME ON THE HF AND ASKED 'WHO GAVE YOU PERMISSION TO CLB TO FL390?' SHANWICK IMMEDIATELY GAVE US PERMISSION TO 'CLB TO AND MAINTAIN FL390;' AND THE CAPT RESPONDED THAT WE WERE ALREADY LEVELED AT THAT ALT. NEITHER GANDER NOR SHANWICK WOULD ADMIT THEY GAVE US THE ORIGINAL CLRNC TO FL390. ALL 3 PLTS IN OUR COCKPIT HEARD THE CLRNC AND ONLY MADE THE ALT CHANGE BASED ON THE CTLR'S REQUEST. SINCE WE WERE AT THE 30 DEG W CHANGEOVER POINT FROM GANDER TO SHANWICK AT THE TIME; I'M NOT SURE WHICH ONE OF THEM MADE THE ORIGINAL REQUEST TO CLB TO THE NEW ALT.
