I was just assuming a single passenger thus ‘yourself’ and normal distance vs fuel. For a couple it’s likely still true as the break even point for fuel would be around 40+MPG. That’s assuming you’re not increasing congestion and thus lowering others fuel economy and flying does not make this trip much shorter or longer.
A family is as you suggest likely better off driving unless they are renting an RV. But, IMO avoiding a 10-20+ hour road trip with a car full of kids is an excusable reason to be less fuel efficient.
PS: At scale things tip further to flying as roads have a separate set of issues.
