Delta pilots are paid in part based on the kind of aircraft they fly. In the proposed new contract between the pilots union and Delta, pilots would receive a series of pay raises during the next three years. These examples of proposed annual pay levels are based on pilots with 12 years seniority and 1,000 flight hours per year (pilots are actually paid by the hour). Under the contract proposal, they would receive an 8 percent raise on the effective date of the deal, a 6 percent increase in 2016 and 3 percent each in 2017 and 2018.
