Since the start of the new aviation season, the global map of direct air connectivity has shifted. Bangkok Suvarnabhumi Airport (BKK) and Delhi Indira Gandhi International Airport (DEL) have both overtaken Beijing Capital International Airport (PEK) in the number of countries served. Suvarnabhumi currently links to 59 countries, Delhi to 57, while Beijing Capital has slipped to 56.
Beijing Capital has long been a cornerstone of China's international network, but its reach is narrowing. Part of the decline stems from the gradual transfer of international services to Beijing Daxing International Airport. Carriers such as Qatar Airways, Etihad Airways, and Royal Brunei Airlines have moved their Beijing operations to Daxing, diluting Capital's country count.
More significant, however, has been the impact of Russian airspace restrictions. Since the onset of the Russia-Ukraine conflict, a host of Western and Asian carriers have suspended or rerouted services to Beijing Capital. Delta Air Lines, American Airlines, British Airways, SAS, SWISS, Austrian Airlines, Finnair, and LOT Polish Airlines have all withdrawn, citing the prohibitive cost of avoiding Russian airspace. Other airlines, including Garuda Indonesia, Ukraine International Airlines, Pakistan International Airlines, Iraqi Airways, Alitalia, and Conviasa, have halted services for their own commercial or geopolitical reasons.
Bangkok's neutral stance pays off
Bangkok's Suvarnabhumi has emerged as a clear beneficiary. Thailand's diplomatic neutrality in the Russia-Ukraine conflict has kept its airspace open to both sides, making it an attractive hub for carriers seeking to expand in Asia without geopolitical complications. LOT Polish Airlines, for example, recently chose Bangkok as a key destination in its Asian capacity expansion. The airport now serves several countries and territories with no direct links to Beijing Capital, including Jordan, Oman, Kuwait, Sri Lanka, Réunion, and New Caledonia.
Delhi's rise is equally notable, reflecting the rapid growth of India's aviation market. European carriers have launched new routes to Delhi in recent years, while Indian low-cost carrier IndiGo has expanded into markets such as Athens. Combined with robust connectivity to Central Asia, the Middle East, and Southeast Asia, Delhi's international network has broadened considerably.
Yet the number of countries served does not necessarily equate to commercial value. Delhi's high ranking is partly a function of its proximity to many smaller markets across Central Asia and the Middle East, which offer limited route potential. Moreover, Delhi benefits from being the sole major airport serving the Indian capital, whereas Beijing's traffic is split between Capital and Daxing. If Daxing were included, Beijing's combined country count would likely still top the list.
Bangkok, too, operates a second airport. Don Mueang International Airport continues to serve more than a dozen countries, though its destinations overlap heavily with Suvarnabhumi's. As with Beijing, the two airports' country counts cannot simply be added together.
It is worth noting that many highly profitable airports serve a relatively small number of countries. Tokyo Narita and Seoul Incheon, for instance, each connect to just over 40 countries. By contrast, Dubai International, Abu Dhabi International, and Hamad International in Doha each offer direct links to 80–90 countries, while Istanbul Airport leads the global ranking with an impressive 112.
For travel professionals, these shifts underscore the importance of monitoring route networks as a barometer of geopolitical and economic trends. The rise of Bangkok and Delhi reflects not only their own strengths but also the changing calculus of airlines navigating a complex global landscape. As new services continue to launch—such as Belavia's new Minsk–Bangkok and Minsk–Phuket nonstops—the competitive dynamics of Asian hubs will remain in flux.
