Under the new agreement, effective from Tuesday, frequent flyers on Singapore Airlines and Air India would be able to earn and redeem miles on flights operated by either carrier.
The agreement comes in the wake of efforts by the national carrier to fulfil the conditions of joining the Star Alliance, of which SIA is a founder member. Air India has already been invited to join the global alliance, which was formed in 1997 and has a membership of 26.
The agreement means that members of SIA's KrisFlyer programme would be able to earn KrisFlyer miles when they fly with Air India, or choose to redeem their miles for flights with the Indian carrier, an SIA statement said.
Likewise, members of Air India's Flying Returns programme would enjoy greater choice by having the option of using their miles on the Singaporean carrier or earning miles when they fly on it, it said.
"Singapore Airlines is pleased to welcome Air India on board. The addition of Air India as a KrisFlyer partner boosts the number of carriers we have such agreements with to 28.
"Those who fly frequently with Singapore Airlines and Air India now have more opportunity to increase their frequent flyer miles, and more choice in deciding how best to use their miles," Huang Cheng Eng, Singapore Airlines' executive vice president marketing and the regions, said.
SIA operates 42 times a week to six destinations in India. With the inclusion of subsidiary carrier SilkAir, the Singapore Airlines route network covers 93 destinations in 38 countries.
