New Delhi: Air India and Singapore Airlines have signed a bilateral agreement that would enable passengers of either carrier to earn and redeem miles on flights operated by the other.

Under the new agreement, effective from Tueday, 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 here.

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.
