He thanked External Affairs Minister Sushma Swaraj for all efforts made to bring back the nurses to India.
The flight includes the 46 Indian nurses from Kerala whose fate in strife-torn Iraq had kept the entire nation on tenterhooks for the past few days.
Reports said many nurses protested at the Erbil airport, saying they won't board the plane unless they are paid their four months' arrear salary.
Indian officials persuaded them, and they finally agreed.
All the 180 passengers, plus three crew members, are reported to be safe, the officials said.
Chandy will receive the nurses at the Kochi airport, where a special immigration desk has been set up.
The Air India flight took off earlier from Erbil, the capital of Kurdistan, after the nurses were freed by the insurgents, following intense Indian diplomatic efforts.
