Narrative:
First officer flying, captain on radio, sea-jnu leg. Given clearance to jnu airport via ssr VOR, ssr 360 degree radial lynns intersection, expect clearance for lda-2 runway 8 jnu, expect no delay from zan. Cleared from FL350 to 11000. Passing approximately FL200, received clearance to 9000 and 'report ssr VOR, expect no delay.' heard an air carrier flight was climbing to 8000, on barlo 6 departure (IMC conditions from 19000 to 4500). Approaching ssr VOR, asked zan if a turn in holding at ssr would help. Zan just said to 'continue.' we crossed ssr VOR at approximately 10500, and reported crossing to zan. 5 mi north of ssr VOR observed large transport pass in opposite direction en route ssr on our TCASII. We were concerned with being 'high' on our descent profile and continued descent to 5100. Heard a very weak, badly broken and unintelligible transmission from zan approaching lynns intersection. Broadcast in the blind to zan that we were switching to jnu tower. Jnu tower rogered our position at lynns intersection, and told us to report barlo intersection. We continued with the jnu lda-2 runway 8 approach with remainder of flight uneventful. Supplemental information from acn 224239: descent was never stopped and at approximately 8200 ft received a TCASII RA with commanded 2000 FPM descent. Followed descent command and RA passed no closer than 1 1/2 mi off right side. Switched to jnu tower after RA and asked if we were now cleared for approach. Supplemental information from acn 224237: being concerned with being high on our approach profile and being on ssr 360 degree radial, captain put 5100 ft inadvertently in altitude select. Continued descent toward 5100 ft.

Title: ALTDEV ALT EXCURSION.
Narrative: FO FLYING, CAPT ON RADIO, SEA-JNU LEG. GIVEN CLRNC TO JNU ARPT VIA SSR VOR, SSR 360 DEG RADIAL LYNNS INTXN, EXPECT CLRNC FOR LDA-2 RWY 8 JNU, EXPECT NO DELAY FROM ZAN. CLRED FROM FL350 TO 11000. PASSING APPROX FL200, RECEIVED CLRNC TO 9000 AND 'RPT SSR VOR, EXPECT NO DELAY.' HEARD AN ACR FLT WAS CLBING TO 8000, ON BARLO 6 DEP (IMC CONDITIONS FROM 19000 TO 4500). APCHING SSR VOR, ASKED ZAN IF A TURN IN HOLDING AT SSR WOULD HELP. ZAN JUST SAID TO 'CONTINUE.' WE CROSSED SSR VOR AT APPROX 10500, AND RPTED XING TO ZAN. 5 MI N OF SSR VOR OBSERVED LGT PASS IN OPPOSITE DIRECTION ENRTE SSR ON OUR TCASII. WE WERE CONCERNED WITH BEING 'HIGH' ON OUR DSCNT PROFILE AND CONTINUED DSCNT TO 5100. HEARD A VERY WEAK, BADLY BROKEN AND UNINTELLIGIBLE XMISSION FROM ZAN APCHING LYNNS INTXN. BROADCAST IN THE BLIND TO ZAN THAT WE WERE SWITCHING TO JNU TWR. JNU TWR ROGERED OUR POS AT LYNNS INTXN, AND TOLD US TO RPT BARLO INTXN. WE CONTINUED WITH THE JNU LDA-2 RWY 8 APCH WITH REMAINDER OF FLT UNEVENTFUL. SUPPLEMENTAL INFO FROM ACN 224239: DSCNT WAS NEVER STOPPED AND AT APPROX 8200 FT RECEIVED A TCASII RA WITH COMMANDED 2000 FPM DSCNT. FOLLOWED DSCNT COMMAND AND RA PASSED NO CLOSER THAN 1 1/2 MI OFF R SIDE. SWITCHED TO JNU TWR AFTER RA AND ASKED IF WE WERE NOW CLRED FOR APCH. SUPPLEMENTAL INFO FROM ACN 224237: BEING CONCERNED WITH BEING HIGH ON OUR APCH PROFILE AND BEING ON SSR 360 DEG RADIAL, CAPT PUT 5100 FT INADVERTENTLY IN ALT SELECT. CONTINUED DSCNT TOWARD 5100 FT.
