If you mean by "on the fly" online: yes, AIX neither requires a recreation of the FS nor do you have to unmount it, you can do it safely while fully accessing the FS.
If you increase the FS AIX will automatically increase the underlying LV too, so you could use "chfs" without even touching the underlying LV. Increasing the LV prior to increasing the FS gives you just better control over the allocation of the PPs used to increase the size of the LV. If you want to use specific PPs from a certain disks (out of several possible ones) you better increase the LV by hand and only then enlarge the FS, otherwise you can immediately enlarge the FS.
I hope this helps.
