The Amsterdam route will never get going.
Wizz have released a winter schedule that is an improvement on last winter at DSA, and have started loading next summers offerings as well, so I see no evidence of them going to EMA. If such a move did happen however, it would probably be the beginning of the end for DSA.
Thomson have a much reduced offering for next year, and FlyBe have cut back Belfast flights compared to what DSA is used to, and no new airlines even on the grape vine.
