The international airport in Puebla was temporarily closed as a precautionary measure, said Puebla airport spokesman Herbert Lopez Palma.
Palma said the airport re-opened after the ash stopped falling and the airstrips were cleaned up.
The temporary closure affected six domestic and international flights to Houston and Dallas, Texas.
Authorities said this week that a lava dome is growing inside the crater and could cause further eruptions.
