Granted, they don't take many flights anyway, but I would think an LCC would still want to encourage loyalty. Of course, these customers are perhaps focused only on price and thus wouldn't fly the LCC even if credits did not expire.</font>
Many of the occasional LCC customers are loyal because of perceived price alone. I say perceived because I can think of several people who blindly book at southwest.com without comparing prices "because they're cheaper and those majors are more expensive."
Obviously, the LCC's do a good job marketing.
