Depends on airline and, mostly, where your flight is. For international longer-haul flights satellite coverage can be rough for airlines - at least a few years ago when I was familiar with it airlines had either global coverage, but slow, or smaller coverage but fast. It'll be interesting if Starlink can solve this for fast-moving planes for airlines like Qantas that fly from Aus to Europe, Asia, and America.
