It still isn't common for that ability to be used in a necessary capacity.
And again, flight doesn't define thebpower level of a character. All the characters in the Legion of Super-Heroes can fly, but most of all aren't very powerful at all. And Hulk is just one example of someone with extreme power that doesn't fly. People mentioned Darkseid (who does fly in certain stories). In the DC universe most of the heroes fly or have some kind of device like Fourth World flying disks. But various powerful villains don't fly, and at Marvel many of the powerful heroes don't fly either.
