I wonder how viable this business model is without a 747, which will be ending it’s production run soon. I’m sure used 747s will be around for a long time, but at maintenance costs go up, parts availability goes down, etc. Eventually the 747 will not be viable, and I’m not sure there’s a suitable replacement.

That's decades away, though. In less than one decade, we may see daily Starship launches for prices that completely obsolete this.
