Air India flew five additional relief flights to Srinagar and two to Leh apart from its scheduled operations.
It also deployed additional Airbus A-320 aircraft to carry out sorties between Jammu and Srinagar flying army and paramilitary personnel and relief materials, including blankets and medicines.
While the national carrier flew a total of 820 passengers on five flights from Srinagar to Delhi, it carried another 150 from Leh on two flights, airline sources said.
Meanwhile, some private helicopter operators have expressed disappointment over not being permitted by the Srinagar air traffic control, which is under the IAF, to operate there to bring back stranded people.
