Capacity expansion takes effect immediately as airlines approach existing flying-right limits, opening room for more flights between major Indian cities and Vietnam
India and Vietnam have agreed to more than double the bilateral air-seat capacity between the two countries to over 16,000 seats a week from around 8,000 currently, marking a significant expansion in aviation connectivity between the two markets.
The increase takes effect immediately and comes as airlines on both sides have used, or are close to using, their existing flying rights amid rising demand for travel between India and Vietnam.
The expansion is expected to provide airlines with greater flexibility to add services on existing routes and potentially introduce additional connections between major Indian cities and Vietnam.
Existing Flying Rights Were Near Exhaustion
Under bilateral air-service agreements, governments allocate reciprocal traffic rights to airlines from each country. These rights determine the number of flights and seats carriers can operate on specified international routes.
The previous capacity limit had increasingly become a constraint as passenger demand between India and Vietnam expanded.
According to Cirium data cited in the report, Indian carriers IndiGo and Air India currently operate around 30 flights a week to Vietnam, while Vietnamese airlines operate around 48 weekly services.
The new agreement provides additional capacity for carriers to respond to the growing demand without being restricted by the earlier bilateral ceiling.
Vietnam Airlines and Vietjet Could Add More Services
Vietnamese carriers are expected to be among the immediate beneficiaries of the additional capacity.
Vietnam Airlines and Vietjet could use the expanded rights to increase services to major Indian metropolitan markets including Delhi, Mumbai, Hyderabad, Chennai and Kolkata.
Vietnam's Sun PhuQuoc Airlines is also planning to launch flights to Mumbai, potentially adding another carrier to the India-Vietnam aviation corridor.
The additional capacity could therefore increase both frequency and competition on routes connecting the two countries.
Vietnam Emerges as a Popular Destination for Indian Travellers
Vietnam has become an increasingly popular destination among Indian tourists, supported by improved air connectivity and easier travel arrangements.
The growth in direct flights has helped reduce travel time and improved accessibility to destinations such as Hanoi, Ho Chi Minh City, Da Nang and Phu Quoc.
Vietnam Airlines' India country manager Nguyen Trung Hieu said the country has become a strong-selling destination from India as connectivity has increased. He also highlighted the airline's A350 aircraft and its positioning as a full-service carrier for premium travellers.
The expansion of seat capacity could further support this tourism trend by increasing the number of available seats and giving travellers more choice in terms of schedules and airlines.
Second Capacity Increase Since 2024
The latest agreement represents the second increase in bilateral seat capacity between India and Vietnam since 2024.
The relatively quick succession of capacity revisions reflects the increase in demand and the growing importance of air connectivity in bilateral tourism and commercial activity.
The two countries have also been expanding cooperation beyond aviation. During the India-Vietnam Joint Commission Meeting earlier this month, the two sides discussed stronger cooperation in trade, supply chains, market access, air connectivity, nuclear energy and space.
Indian Airlines Also Stand to Benefit
The expanded bilateral capacity is not limited to Vietnamese carriers.
Indian airlines will also have additional room to expand services to Vietnam, subject to their commercial plans and available aircraft.
IndiGo and Air India currently operate services to Vietnam, and the additional capacity could allow Indian carriers to increase frequencies or explore additional city pairs.
For Indian airlines, international expansion is increasingly important as carriers look to diversify revenue sources and increase aircraft utilisation.
However, the commercial viability of additional services will depend on passenger demand, aircraft availability, airport slots, fuel prices and route economics.
Impact on Airfares and Passenger Choice
Higher seat capacity can increase competition and potentially provide passengers with more choices in terms of airlines, schedules and fare options.
When airlines have limited bilateral rights, capacity constraints can restrict the number of seats available even when underlying demand is strong. Additional capacity can help airlines respond more directly to seasonal and structural increases in passenger traffic.
The actual impact on airfares will depend on how quickly airlines deploy the newly available capacity and how demand develops.
If multiple carriers increase frequencies simultaneously, competition could intensify on key routes. If demand grows faster than available capacity, however, fares could remain relatively firm despite the higher bilateral ceiling.
Opportunity for Aviation and Tourism Businesses
The increase in connectivity could have wider economic implications beyond airlines.
More direct flights can support tourism, hotels, travel agencies, airport operators and other businesses associated with international travel.
Indian tourists travelling to Vietnam generate demand for accommodation, local transportation, restaurants, entertainment and other tourism services.
Similarly, stronger connectivity can make it easier for Vietnamese travellers and businesses to access Indian cities.
The additional flights could therefore contribute to broader people-to-people and business links between the two economies.
Broader Southeast Asia Travel Boom
The India-Vietnam development comes against a broader increase in Indian travel to Southeast Asia.
Countries across the region have benefited from stronger Indian outbound tourism as airlines expand connectivity and several destinations have eased or simplified visa arrangements for Indian travellers.
Improved connectivity can create a reinforcing cycle: more flights increase destination awareness and accessibility, while stronger demand encourages airlines to add further capacity.
Vietnam's growing popularity among Indian tourists has made the country an increasingly important market for airlines operating between India and Southeast Asia.
Competition and Cost Pressures Remain Key Factors
While additional international flying rights create opportunities, airlines will still face significant operational challenges.
Aircraft availability, aviation turbine fuel prices, airport charges, foreign-exchange movements and geopolitical disruptions can affect route profitability.
Indian aviation capacity has faced pressure from higher operating costs and international disruptions. Recent industry data has also shown capacity reductions on several routes amid elevated fuel costs and geopolitical uncertainty.
Consequently, airlines will need to balance the opportunity created by the additional Vietnam rights with route-level economics.
Market Outlook
The increase in India-Vietnam bilateral air capacity to more than 16,000 seats a week creates additional room for airlines to respond to rising passenger demand and expand connectivity between the two countries.
For the aviation sector, the development could support international capacity growth, while for travellers it should provide greater choice of flights and schedules. Vietnam Airlines, Vietjet, IndiGo and Air India could all have opportunities to deploy additional capacity, depending on their commercial strategies.
The broader opportunity extends to tourism, hospitality and travel-related businesses as stronger connectivity can encourage both leisure and business travel.
The key factors to monitor going forward will be how quickly airlines utilise the newly available rights, whether new routes are launched, the response of passenger demand and the impact of fuel costs and competitive pricing on route profitability.
