In my humble opinion, no, it's not worth it. Salary aside (and salary, mind you, is a big motivational factor), you don't get to see the world as a LCC cabin crew without long-haul fligths, and trust me, you'll get jaded in a short while. SQ for instance, very much prefers fresh new CC, as these are the people who are willing to learn and more "teachable", unlike experienced CC who thinks they know it all. This particular trait is much sought after by the airline. if you think joining a LCC can gain you an edge, you may be mistaken. Why waste your precious 2 years in a place where you know will not get you anywhere? I'll definitely give the LCC a miss.
