Air India and Singapore Airlines Open Up Their Codeshare From October 15

October 7, 2026 — Air India and Singapore Airlines will loosen their codeshare from October 15, letting customers book either airline’s India–Singapore flights on their own through the other carrier, and will add reciprocal frequent-flyer perks in 2027.

What happened

Air India announced the change on October 7. It is the first step under the commercial cooperation agreement the two airlines signed in January 2026.

Until now, a codeshare booking had to include flights operated by both airlines. From October 15, 2026, that requirement goes. A customer can buy an eligible Singapore Airlines flight through Air India, or an Air India flight through Singapore Airlines, as a standalone trip.

The loyalty step comes later. From the second quarter of 2027, Maharaja Club Platinum and KrisFlyer PPS Club members get priority check-in and boarding on the partner airline. Maharaja Club Silver and KrisFlyer Elite Silver members get extra baggage and priority boarding on eligible routes.

What it means for travelers

• Expect fuller flights between India and Singapore. Each airline can now sell the other’s seats on 126 weekly flights without a connecting leg, which should lift bookings from October 15.
• Flight numbers can mislead. More flights will carry both AI and SQ codes. Check which airline operates your flight, not just the marketing code.
• Priority boarding lines get longer in 2027 as partner elites gain reciprocal benefits.
