In some parts of the world there is a perception that a degree in itself has value, and this will increase your chances of promotion. Singapore by reputation is one of those parts of the world.
However, in the aviation world specifically there are two questions that will get asked of you:
(1) Have you the licences to do the job
(2) How well do you do it.
If a specific degree makes you better at doing the job, then in aviation, it will improve your promotion chances. Just a degree for the sake of having a degree however, will have no value, in an aviation environment.
