Yes !!!
My hubby & I flew Spirit round trip from National in DC to Ft. Lauderdale last summer. I absolutely would fly Spirit again. The staff seemed much more safety conscious than our usual carrier, Delta, & we were pulled back from the gate & in the air a few minutes early both ways leading to early arrivals both ways. Best of all - the price couldn't be beat! From our area, their destinations are extremely limited so one would need to check their site to see their origin/destination availability, but if it's in the area you can fly from or to, I would recommend Spirit.
