The USA on 4 May will halt travel from India except for US citizens as Covid-19 infections in India have spread faster than during any other single day of the global pandemic, with that nation reporting a record high of 380,000 new infections on 29 April. The White House on 30 April announced the forthcoming temporary ban at the advice of the US Centers for Disease Control and Prevention because of the multiple Covid-19 variants in India that are spreading at "extraordinarily high" infection rates. Daily new cases of Covid-19 in the Asia-Pacific region have spiked since March, driven largely by an outbreak in India, where each day breaks the previous day's record in the number of new cases reported, World Health Organization data shows. The spread increased exponentially in India during April, as hundreds of thousands of people every day reported new infections of Covid-19. Cases in India have spiked just as new infections in the USA have begun to decline in part due to vaccination efforts.The US State department as of 22 April had already listed a "Level 4: Do Not Travel" advisory for Americans on its website. The State department as of 22 April applied its "do not travel" warnings to more than 100 nations compared with 33 nations at the start of April, and now warns Americans against travelling to nearly every nation in the Asia-Pacific region. Americans are advised by the department to "reconsider travel" to China, Japan and Australia, which are labeled with a "Level 3" warning. The USA since 26 January has required all inbound travellers on international flights to provide a negative coronavirus test that is less than 72h old to enter the nation. A multinational relief effort is sending medical supplies to India, including masks and raw materials for vaccine production. In a statement on Twitter on 29 April, US Secretary of State Antony Blinken said “just as India came to our aid early in the pandemic, the US is committed to working urgently to provide assistance to India in its time of need”.

United Airlines has finalised terms with the US Treasury Department for the $2.8 billion the carrier will be receiving under the third iteration of the payroll-support programme (PSP3).

US majors American Airlines, Delta Air Lines, Southwest Airlines and United during the second quarter will receive a combined $722 million in PSP2 funds and $11.1 billion through the third version of the payroll-support programme, which was authorised by the American Rescue Plan Act signed into law by US president Joe Biden on 11 March. The four carriers' combined operating losses in the first quarter of 2021 reached $5.4 billion.

Thai Airways International has pushed back the deadline on indications of interest and indicative proposals from potential buyers for three Airbus A330-300s to 1 May, 17:00 (Bangkok time). The airline had earlier set the target of 26 April for indicative bids on the 2009-vintage aircraft (MSNs 0990, 1003 and 1035), which are powered by Rolls-Royce Trent 700 engines. Thai Airways says the actual sale of the aircraft is conditional on its rehabilitation plan, which requires an approval from creditors and the Central Bankruptcy Court of Thailand.
