Two Star Alliance Carriers Now Sell Each Other's Seats Direct

Two Star Alliance carriers now Sell Each Other's Seats directly to travelers, and the change makes booking flights between India and Singapore noticeably simpler. Since mid-October, Singapore Airlines and Air India have been able to sell eligible flights operated by the other carrier through their own websites, apps and travel agents — no longer requiring the ticket to include a flight on the selling airline, according to travel outlet I-Journey, which cited reporting from Business Today and eTurboNews.

The arrangement covers 126 weekly flights between Singapore and eight Indian cities: Ahmedabad, Bengaluru, Chennai, Delhi, Hyderabad, Kochi, Kolkata and Mumbai. In practice, a traveler who prefers one airline's booking tools can now buy the other's seat there as a standalone ticket, comparing schedules and fares without hopping between sites.

What changed this month

Before the shift, the two airlines could only sell each other's flights as add-ons bundled with one of their own services. That is the old codeshare model: convenient for connections, but useless if you simply wanted the partner's nonstop and liked the other airline's app. The new setup removes that restriction, so either carrier's storefront can sell the other's eligible India-Singapore flights on their own.

Timing matters here. The change took effect just as the year-end travel season approaches, when demand on India-Singapore routes runs hot with family visits, weddings and holiday trips. Being able to price both carriers' options in a single search should make fare comparison faster — and harder for either airline to hide a cheaper seat behind a clunkier booking flow.

What frequent flyers actually get

Loyalty members see the most immediate upside. Members of the Indian carrier's Maharaja Club and the Singapore carrier's KrisFlyer program can already earn miles across more booking classes and eligible flights on either airline, which widens the cheapest fares that still earn credit.

More is scheduled. From the second quarter of 2027, top-tier members are due priority check-in and boarding across both airlines, while Silver-level members are promised extra baggage allowance and priority boarding. The airlines say they are also working on tighter schedule connections to cut layovers and on new corporate offerings, though neither project has a date yet.

Some context keeps the excitement honest: both carriers already belong to the same global alliance, so reciprocal privileges such as lounge access and basic mileage earning existed before this deal. What is genuinely new is the standalone sale — the ability to buy the partner's flight as the whole ticket, not just an attachment to your own.

Why it matters for your next booking

For anyone flying the corridor, the practical win is choice. If you trust one airline's website, app or customer service more, you can now buy the other's seat through the channel you prefer and still have a single point of contact if something goes wrong. Travelers who Sell Each Other's Seats through one storefront also get one itinerary to manage instead of two separate bookings stitched together by hand.

A few caveats still apply. Earning rates and benefits can vary by ticket class, so check the fare rules before assuming the cheapest fare earns full miles. And while the airlines promise smoother connections, the improved schedules have no launch date — so for now, leave the usual buffer between separate tickets if you are building your own itinerary.

The broader trend is worth watching: airlines are steadily unbundling the old alliance playbook, selling partner inventory the way retailers sell each other's products. For passengers, that usually means better price transparency. Just remember that when carriers Sell Each Other's Seats, the operating airline still sets the onboard experience — so pick the flight for the seat and schedule, and the storefront for the service.

Flying is getting more complicated to navigate in other ways too. A new airline delay rule could cut the free meals and hotel stays travelers have come to expect when flights go wrong, so knowing your rights matters as much as finding the fare. And if your travels take you further afield, the US recently eased its Tanzania travel warning after a year of high caution — a reminder to check advisories before you book, not after.
