I recently used Allegiant for a spontaneous trip, and I wasn’t sure where they actually fly at first. What I discovered is that Allegiant focuses on connecting smaller regional airports to popular vacation destinations—which worked perfectly for my needs. I called 8 4 4-7 3 4-0 8 1 3 to double-check route options and get help booking, and the agent walked me through all the possible cities they serve from my home airport. It was really helpful because I’d assumed I had to connect through a major hub, but Allegiant flew direct to my destination. Later when I needed to tweak my return date, modifying my flight was stress-free too. From my experience, Allegiant can be a great option if they serve your city!
