Air India-Singapore Airlines booking changes: October 15 guide

Air India and Singapore Airlines are making eligible flights between India and Singapore easier to buy from October 15, 2026. A qualifying flight operated by either airline will be able to appear as a standalone option on the other carrier's website, app or appointed travel agency.

The change covers 126 weekly flights linking Singapore with Ahmedabad, Bengaluru, Chennai, Delhi, Hyderabad, Kochi, Kolkata and Mumbai. It expands where travelers can shop; it does not turn the two airlines into one operation or make every fare, flight or loyalty benefit identical.

The practical answer: From October 15, an eligible Singapore Airlines-operated India flight can be sold on its own through Air India, and an eligible Air India-operated flight can be sold on its own through Singapore Airlines. Before paying, compare the operating carrier, fare conditions, baggage, seat selection and mileage-earning line. The newly announced reciprocal status benefits do not begin until the second quarter of 2027.

What changes on October 15

The airlines' joint announcement removes a restriction in their present codeshare sales. Today, an eligible Air India-operated flight booked through Singapore Airlines must be combined with a Singapore Airlines-operated sector, and the reverse applies to a Singapore Airlines flight booked through Air India.

From October 15, that extra operated segment will no longer be required for eligible India-Singapore flights. For example, a traveler may be able to buy a Singapore Airlines-operated Bengaluru-Singapore flight through Air India without adding an Air India-operated connection.

The important word is eligible. The announcement does not publish a complete flight-number or fare-class list, and it does not promise that every flight will appear in every channel on every date. If the option is missing, check the operating airline as well as the partner site.

Eight Indian cities are in the first phase

The first phase covers services between Singapore and these cities:

• Ahmedabad;
• Bengaluru;
• Chennai;
• Delhi;
• Hyderabad;
• Kochi;
• Kolkata; and
• Mumbai.

The stated 126 weekly flights are the combined service covered by the initiative, not 126 new flights. The announcement does not add a route or a frequency by itself. It changes the shopping and booking options across existing eligible services.

Air India and Singapore Airlines signed the broader commercial cooperation framework in January. That framework set out possible work on schedules, fares, corporate travel and frequent-flyer benefits, subject to approvals. The October announcement is the first defined passenger-facing phase.

Check who operates the flight before comparing prices

A partner-marketed flight can carry one airline's flight number while the other airline operates the aircraft. The booking result and e-ticket should say “operated by” beside the segment. That line matters more than the website used to find the fare.

The operating carrier normally controls airport check-in, onboard service and operational updates. The ticketing or marketing carrier may control voluntary changes, refunds and some paid extras. If a booking is made through a travel agency, the agency may remain the first contact for ticket changes.

Compare like with like. A lower result can come with a different fare family, change fee, refund rule, checked-bag allowance or seat-selection charge even when the aircraft and departure time are the same.

Baggage and seats still need a booking-level check

Neither airline says the October change creates one universal baggage allowance. Air India's checked-baggage guidance and Singapore Airlines' allowance page both direct passengers to route-, cabin-, fare- or itinerary-specific rules.

Read the allowance printed in the booking before purchase and again on the e-ticket. If the trip includes another carrier or a connection, ask which rule applies to the complete journey rather than copying the allowance from a standalone flight search.

Seat maps can also differ between the selling airline and the operating carrier. If a seat cannot be selected in the original booking channel, use the operating carrier's manage-booking tool with its reservation reference or contact the ticket issuer. A displayed seat is still subject to aircraft changes.

Mileage earning changed in April, but fare class still matters

The two airlines expanded reciprocal mileage earning in April 2026 by adding eligible booking classes and revising earn rates across cabins. That means more qualifying Air India and Singapore Airlines-operated flights can earn Maharaja Points or KrisFlyer miles.

It does not mean every codeshare earns in both programs. Air India's current Singapore Airlines partner chart ties earning to the operating airline and eligible booking class. Note the marketing and operating flight numbers, fare class and loyalty number before travel, then keep the boarding pass until credit posts.

Choose one program for a sector. Crediting the same flight to both Maharaja Club and KrisFlyer is not supported by the announcement.

The new status benefits are planned for Q2 2027

The announcement separates current mileage earning from future reciprocal benefits. From the second quarter of 2027, on eligible routes:

• Maharaja Club Platinum and KrisFlyer PPS Club members are due to receive priority check-in and boarding with the other airline; and
• Maharaja Club Silver and KrisFlyer Elite Silver members are due to receive additional baggage and priority boarding.

Those benefits are not in force on October 15, 2026. The airlines have not yet published the precise start date, eligible-route list, allowance amount or recognition process. Until they do, rely on the benefits shown in the live booking, account or e-ticket rather than the 2027 preview.

Connections may improve later, but no shorter layover is guaranteed

Air India and Singapore Airlines say they are working on schedule coordination intended to reduce layovers and waiting times. They have not announced a new connection timetable as part of the October phase.

For a current trip, use the connection and terminal information in the actual itinerary. Confirm that every sector is on the same ticket, whether baggage is checked through and which airline handles a missed onward flight. A codeshare label does not protect separately purchased tickets.

At Changi, follow the airport's current transit guidance. Anyone who must enter Singapore should also check visa requirements and the SG Arrival Card; the card is not a visa.

Mobile data for an India-Singapore trip

OpenSim's live catalog had plans for India, Singapore and an Asia 20 areas option covering both countries when this guide was reviewed.

A country plan can suit a stay focused on one side of the route. The regional option can avoid switching data plans on a return or multi-country itinerary, but check its allowance, validity, speed policy and price against the specific trip.

Install the eSIM while reliable Wi-Fi is available and follow the selected package's activation instructions. An eSIM supplies mobile data on supported ground networks. It does not provide inflight Wi-Fi, change airline app access rules or protect a connection.

Ten questions about the Air India-Singapore Airlines changes

Can I book a Singapore Airlines-operated flight on Air India's website by itself?

From October 15, eligible India-Singapore flights can be sold standalone through the partner carrier. Availability still depends on the flight, date, fare and channel, so also check Singapore Airlines if a result is absent.

Can I book an Air India-operated flight through Singapore Airlines without an SIA connection?

Yes, for eligible services from October 15. The old requirement to combine it with a Singapore Airlines-operated sector is being removed.

Does the change add new flights between India and Singapore?

No. The 126 weekly flights describe the services covered by the cooperation. The announcement changes booking access, not the published route count or timetable.

Which Indian cities are included?

Ahmedabad, Bengaluru, Chennai, Delhi, Hyderabad, Kochi, Kolkata and Mumbai are named in the first phase. Other Indian cities may still be reachable by connection, but they are not listed as nonstop points in this announcement.

Which airline do I check in with?

Start with the airline operating the first flight, as identified on the itinerary. Follow any different instruction in the booking confirmation because airport arrangements can vary.

Which baggage allowance applies to a codeshare ticket?

Use the allowance displayed during booking and printed on the issued e-ticket. Do not assume the operating airline's standalone allowance or a status benefit applies to a partner-marketed fare.

Can I select a seat on the other airline's aircraft?

Often, but the selling website may not expose the operating carrier's full seat map. Try the operating airline's manage-booking page with its reference or ask the ticket issuer; seat assignments can still change.

Will I earn Maharaja Points or KrisFlyer miles?

Eligible operating airline and booking classes can earn after the April expansion. Check the chosen program's partner chart for the exact fare class, add one loyalty number and retain the boarding pass.

Can I use Maharaja Points or KrisFlyer miles for every partner flight?

No. Award inventory and cash codeshare availability are separate. A flight can be sold for cash without being released as a partner award, and points cannot simply be transferred between the two programs.

Do the new baggage and priority benefits start on October 15?

No. The announced reciprocal status benefits are planned for the second quarter of 2027. The airlines still need to publish the exact start date, eligible routes and operating details.

Before buying through the partner airline

• Search the same flight on both airline websites and compare the complete fare conditions.
• Confirm the operating carrier, flight number and airport for every segment.
• Check that all connections appear on one ticket if through protection matters.
• Read the baggage allowance on the checkout page and issued e-ticket.
• Record the fare class before choosing a loyalty program.
• Use the operating carrier for check-in unless the itinerary says otherwise.
• Keep the ticketing airline or agency's details for changes and refunds.
• Treat Q2 2027 status benefits as future, not current, entitlements.
• Check entry and transit requirements for the passport and itinerary.
• Save the itinerary, reservation references and essential travel details offline.

Air India-Singapore Airlines source record

The October 7 joint release controls the October 15 sales change, 126 weekly flights, eight-city scope, April mileage update and Q2 2027 benefit plan. The airlines' January framework supports the broader cooperation context. Current airline baggage, check-in, manage-booking and loyalty pages support the practical checks, while Changi Airport and Singapore ICA support transit and entry preparation.

Public traveler questions informed the sections on missing partner results, award inventory, baggage, seats, points, upgrades and status recognition. They were used to identify uncertainty, not as policy evidence.

Review this guide on October 15 after partner inventory appears, when the airlines publish the 2027 benefit terms, or sooner if they change the participating cities, eligible routes, mileage charts or booking rules.
