How can I use the Boarding Pass details received on the mobile / e-mail id?
A.
After your check-in is successfully completed, a Boarding Pass PDF would be sent to your registered e-mail address. Also, the details will be saved on your phone under "my trips”.You can take a print of the Boarding Card and carry the same to the airport, or else show the Booking or Check-in details on the Phone at the check-in counter along with a photo ID card and obtain the printed boarding card.
While doing a mobile check-in for international flights ex-India you will only receive a confirmation email and the boarding pass will have to be collected at the Airport before proceeding to clear Security and Government formalities, the Indian Government requires you to carry the physical print of the Boarding Pass.
For travel to select airports which are enabled for 2D Mobile Boarding Pass processing, you will receive a 2D Mobile Boarding Pass on your mobile handset which can be scanned at the enabled airports to clear the government formalities.
