individual account can be checked here https://www.airtel.in/dthaccount/wps/myportal/
i had just checked by this link and it opened my account package info page
Open this link , select Digital tv and enter your registered Mobile number , you will get OTP option if you do not have registered password. After entering these you can go to that myaccount page.
Airtel digital tv has the most worst my account login page system in DTHs in India.
