What's next: Carriers may add more routes under the agreement after initial launch.
Launch covers Singapore Changi Airport (SIN), Noi Bai International Airport (HAN), Tan Son Nhat International Airport (SGN), and Da Nang International Airport (DAD).
Singapore Airlines is a Star Alliance member, and Vietnam Airlines is a SkyTeam member, so alliance benefits vary by program.

Snapshot

From October 26, 2025, Singapore Airlines and Vietnam Airlines will codeshare across five Singapore-Vietnam city pairs, improving day-by-day choice and through-booking. The initial scope places Singapore Airlines' code on Vietnam Airlines flights between Singapore and Hanoi, and Singapore and Ho Chi Minh City. Vietnam Airlines will add its code to Singapore Airlines flights between Singapore and Da Nang, Singapore and Hanoi, and Singapore and Ho Chi Minh City. Tickets are slated to be available starting October 10 via both airlines and travel agents, with operations contingent on regulatory approvals. Expect coordinated schedules at Singapore Changi Airport (SIN) for smoother connections into each carrier's broader network in Southeast Asia and beyond.

Background

The tie-up builds on a multiyear relationship, including a 2023 memorandum to deepen commercial collaboration. While both carriers are flag airlines, they sit in different alliances, which shapes elite benefits and mileage accrual. Singapore Airlines belongs to Star Alliance, and Vietnam Airlines belongs to SkyTeam. A bilateral codeshare lets travelers book single-ticket journeys with through-check of bags and coordinated customer service, even without a joint venture.

The launch focuses on high-demand routes linking Singapore with Hanoi and Ho Chi Minh City, plus leisure-heavy Da Nang, a central-coast gateway that has grown into a major beach and meetings market.

Latest Developments

Codeshare routes, on-sale date, and what to expect first

At launch, the codeshare covers three Singapore Airlines-operated links, Singapore to Da Nang, Singapore to Hanoi, and Singapore to Ho Chi Minh City, and two Vietnam Airlines-operated links, Singapore to Hanoi and Singapore to Ho Chi Minh City. Inventory opens progressively on October 10, 2025, through each airline's sales channels and travel agencies. All flights are subject to regulatory approvals, which is standard language when partners align schedules and marketing. Travelers should expect basic reciprocal recognition on the marketing carrier's ticket, with mileage earning and benefits governed by each airline's program and alliance rules. As schedules firm up for the Northern Winter season, look for added bank-to-bank connectivity at Singapore Changi Airport (SIN) and improved options for same-day returns between Singapore and both Hanoi and Ho Chi Minh City.

Analysis

For travelers, the immediate value is schedule density and simplified booking between two business and leisure corridors. Codeshares let you keep segments on one ticket, which streamlines reaccommodation during irregular operations and enables through-checked baggage. Because Singapore Airlines and Vietnam Airlines sit in different alliances, premium-tier perks do not map one-for-one across both carriers. Earning and lounge access will follow the operating and marketing rules of KrisFlyer and Lotusmiles, with alliance-based benefits applying only on the respective networks. That is common for cross-alliance codeshares and does not diminish the convenience of added flight numbers and timing choices.

The route selection makes strategic sense. Hanoi and Ho Chi Minh City are core business markets, while Da Nang adds a high-growth leisure and meetings destination to the mix. Expect the carriers to test day-parts that create better connections across Southeast Asia, South Asia, and Oceania, especially over Singapore Changi Airport (SIN), where Singapore Airlines can feed long-haul banks. Vietnam Airlines gains additional visibility in Singapore point-of-sale and a pathway to sell Da Nang via a familiar premium brand. If the partnership scales, the next logical steps would be wider interline cooperation, selective domestic add-ons in Vietnam, and deeper schedule coordination during peak seasons. For now, the launch offers practical benefits without complex rule changes, which is often the fastest way to improve real-world options on the Singapore-Vietnam corridor.

Final Thoughts

This launch gives the Singapore-Vietnam corridor more frequency, better timing, and simpler single-ticket journeys, especially for travelers mixing business in Hanoi or Ho Chi Minh City with leisure in Da Nang. Watch October 10 for the first wave of fares, then October 26 for operations, subject to approvals. As both airlines align timetables, you should see tighter connections at Singapore Changi Airport, plus clearer paths to earn miles based on the operating carrier's rules. If cooperation expands, additional routes could follow. For now, the Singapore Airlines Vietnam Airlines codeshare is a straightforward win on high-demand city pairs.
