airBaltic will equip its fleet with Starlink

Kudoes to AirBaltice and Starlink. "Starlink, which can deliver up to 350 Mbps to aircraft..." this compares to a measly 3-5 Mbps on most large airlines - and they charge for that "service".
The question that arises though: is that 350Mbps per aircraft? - which suggests that the more users there are that 350 Mbps is distributed between them which means for every extra user the speed reduces for each user.
