Spirit Airlines Seat Assignment Algorithm
When I flew with Frontier Airlines, I realized that they assigned the seat from front to back. Therefore, I checked the available seat carefully before I checked in, and got an ideal seat (aisle seat) for both out bound and in bound. I know that Air Asia also has the same seat assignment algorithm and I was always success choosing the seat without seat assignment fee.
Now, I will be flying with Spirit Airlines this weekend. I didn't purchase the seat assignment. Do they have the same or similar seat assignment algorithm as Frontier?
