The way Starlink works SpaceX has no means to prioritize airplanes over residential. If you wait for service in residential area it's because it's oversubscribed and SpaceX has to put more satellites in orbit or build more ground station. Those satellites are the same that support airplanes so they benefit all use cases. The issue is coverage i.e. bandwidth per area. The way Starlink works is that bandwidth (satellites) is more or less uniformly distributed over area. They can't just add one satellite over a city in Canada to provide more service there. To double available bandwidth in Canada they have to double the number of Satellites. Airplanes (and boats) don't compete for bandwidth with residential because most of the time they are over areas without other Starlink users. The antennas are not the same so it's not like an airplane antenna fights with residential antenna. If anything, making more money boats and airplanes helps SpaceX build satellites and antennas faster so this service is a win for residential as well.
