The raids came after President Bashar al-Assad said Damascus was being informed about air strikes against jihadists in Syria and that they could help his government if they were "more serious".
Emirati F-16s that flew in to Jordan on Sunday carried out raids against IS, "hitting their targets and returning safely to base", the UAE armed forces command said.
It did not specify how many aircraft were in action, or where or what their targets were.
The jihadists later killed the airman by burning him alive, releasing gruesome video footage of his "execution".
