Have you been involved with any projects in the department; fuel savings program, electronic flight bag, standardization, etc?
That will help you a little when you're trying to sell your point about a raise because I think that stuff gives you more worth in the department. Industry surveys will also help you provide proof to what you are requesting.
Unfortunately in this part of the industry I have heard a lot of people on here say that sometimes the only way to get a decent pay raise is get a new job because it ultimately depends on the owner.
