The European Union Aviation Safety Agency has warned carriers to avoid Iranian airspace given the "potential for US military action" in the country. In a Conflict Zone Information Bulletin (CZIB), EASA notes that Iranian air defence forces are on a "heightened state of alert", leading to an increased risk of misidentification. Civil air traffic therefore faces a “high risk” at all altitudes and flight levels, adds the agency. Should military action break out, it warns, retaliatory action could be launched across the region, affecting the airspaces of neighbouring countries. The CZIB, issued on 16 January, lasts until 16 February. EASA issued CZIBs relating to Iranian airspace last summer as conflict broke out between the USA, Israel and Iran.

Industry body Airlines for Australia and New Zealand (A4ANZ) has backed calls by the country's competition regulator to restrain the monopoly power that the country's airports have when negotiating aeronautical charges. In a submission to a Senate committee on transport and rural affairs, the Australian Competition and Consumer Commission (ACCC) repeated its long-held position that "stronger regulatory oversight of the major airports is required to prevent them from exercising their market power and imposing higher charges on airlines, including those that operate in regional areas". The ACCC monitors and has oversight of airport aeronautical charges under legislation, but the body says that this "no longer acts as a constraint on behaviour because there is less of a threat of regulatory action than there was when the regime was first introduced over [two] decades ago". Instead, it is supporting calls by airlines to introduce a "negotiate/arbitrate" scheme that would allow for any breakdowns during negotiations with airports to be resolved by a third party. "We considered that this would incentivise the major airports to negotiate with the airlines in good faith," it adds. In response, A4ANZ chair Graeme Samuel says in a 19 January statement that the group supports the ACCC recommendation. "Commercial arbitration frameworks are common in other industries and cover all significant agreements. Arbitration would incentivise airports to negotiate in good faith and prevent excessive charges that harm consumers and the broader economy," he adds. Samuel is a former commissioner of the ACCC and says that with A$44 billion ($29.4 billion) of capital works planned for airports in the country "passenger charges are set to rise substantially, inevitably feeding into higher airfares and cargo prices". A 2019 inquiry by the government's Productivity Commission considered a negotiate/arbitrate framework for setting aeronautical charges but found that airports were not systematically abusing their market power, and there was "no justification for significant change to the current form of regulation of aeronautical services at any of these airports at this time". In its response, the government at that time agreed with the Commission's view, finding that there was "no current justification for significant change to the current form of 'light handed' economic regulation" of airports.

Air India and Singapore Airlines have signed a framework agreement that will pave the way for greater connectivity between their networks. The commercial cooperation framework agreement was signed on 16 January in Mumbai and sets a way forward to seek regulatory approvals for "definitive joint agreements" that would allow them to align schedules and the potential for cross-participation in each other's business travel programmes. "Air India and SIA also plan to explore opportunities to broaden the scope of their cooperation in select markets, beyond Singapore and India, subject to regulatory approvals," they add. "This would meet the growing demand for global connectivity, support traffic flow through both carriers' hubs, and strengthen the air travel markets of both India and Singapore." SIA holds a 25% stake in Air India, with the remaining 75%India'sy India's Tata Group. The two airlines have existing codeshare arrangements covering several routes from India and Singapore
