ASEAN Nations Launch Open Skies Initiative for Secondary Cities

The Philippines, Indonesia, Malaysia, Thailand, and Vietnam have jointly launched a groundbreaking ASEAN Open Skies initiative designed to expand low-cost aviation access to secondary cities across Southeast Asia. Announced on May 13, 2026, the policy aims to liberate budget travel by opening competitive air routes to destinations that have historically been underserved by major airlines.

The initiative specifically targets the structural aviation inequity that has long concentrated affordable flights within the region’s primary hubs. For years, budget travel has been largely limited to routes connecting major capitals and commercial centers, including Manila, Jakarta, Bangkok, Kuala Lumpur, and Ho Chi Minh City.

By shifting the focus toward secondary cities, the five-nation agreement seeks to make the region’s less-connected destinations more accessible and affordable for budget travelers from across Asia, the Pacific, Europe, and North America.

Expanding Access to Secondary Destinations

A core objective of the 2026 initiative is to unlock routes to “hidden gems” and underrated cities that were previously overpriced or inaccessible to those traveling on a budget. The policy identifies several key secondary cities as primary targets for expanded low-cost carrier access.

• Cebu in the Philippines
• Penang on the northwest coast of Malaysia
• Chiang Mai in northern Thailand
• Medan in Sumatra, Indonesia

The initiative intends to break the reliance on major hubs by creating a regulatory environment where airlines can fly directly between these secondary cities and other regional destinations without the necessity of routing through a primary capital city.

Regulatory Framework and Carrier Participation

To achieve these goals, the participating governments are establishing a new regulatory framework tailored for low-cost carriers (LCCs). This framework is designed to encourage airlines to venture into less-served cross-border routes that were previously considered financially risky or regulatorily complex.

Several prominent low-cost carriers are expected to play a central role in the expansion. The initiative specifically names the following airlines as key participants in the push to increase regional connectivity:

• Cebu Pacific
• AirAsia
• Lion Air
• Nok Air
• VietJet

To support these carriers in establishing new routes, the five participating nations are providing government-backed incentives. These measures include reduced airport fees and targeted infrastructure investments to ensure that secondary airports can handle the increased volume of budget travelers.

Regional Aviation Growth and Impact

The timing of the initiative coincides with a period of significant growth in the Southeast Asian aviation sector. Reports indicate that the Philippine aviation sector, in particular, has recorded the fastest growth in the region, positioning the Philippines as a key player in the broader budget skies strategy.

Industry analysts suggest that this development represents the most significant shift in Southeast Asian budget travel since the initial low-cost carrier revolution of the early 2000s. By removing the barriers to secondary city travel, the initiative is expected to distribute tourism more evenly across the five participating nations, benefiting local economies outside of the major metropolitan hubs.

The move is designed to transform the travel landscape for budget-conscious tourists by reducing the cost of reaching remote or underrated destinations, effectively decentralizing the region’s aviation network.

As the regulatory frameworks are implemented, the initiative aims to foster a more competitive environment among LCCs, which is expected to lead to lower fares and increased flight frequencies for travelers navigating the diverse landscapes of the Philippines, Indonesia, Malaysia, Thailand, and Vietnam.
