Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for bonding of satellite terminals. In some implementations, a first satellite terminal with a first satellite communication link determines that it is in communication with a second satellite terminal that has a second satellite communication link. The first satellite terminal receives packet data from a data source and selects first packet data for transmission over the first satellite communication link and second packet data for transmission over the second satellite communication link. The first satellite terminal transmits the first packet data over the first satellite communication link, and provides the second packet data to the second satellite terminal for transmission over the second satellite communication link.
