ZIPAIR Tokyo has fully deployed Starlink on its entire fleet (100% coverage), strongly suggesting availability on all routes including SJC-NRT. However, there are no direct observations on this specific route, and no recent airline-specific news or community sightings confirming Starlink on SJC-NRT flights. The only relevant community sighting is on a different route (NRT-LAX), indicating Starlink use on transpacific flights from Narita. Given the full fleet coverage and indirect evidence, the probability is anchored conservatively below 1.0, set at 0.40 to reflect high likelihood but lack of direct route observations.
