Beginning in November, the USA, will lift quarantine restrictions for non-essential travellers arriving in the nation who are fully vaccinated against Covid-19, giving hope to airlines for a resurgence of international travel following a similar policy decision in Canada. Travellers to the USA will need to provide proof of vaccination and recent negative Covid-19 test results before boarding a flight to that country, the White House's Covid-19 response coordinator Jeff Zients said on 20 September. The USA decided on this strategy after consulting for months with working groups that vetted options within US agencies and with other governments to create "equitable and clear policy", White House press secretary Jen Psaki said on 20 September during a briefing. "The older rules were not equitable in our view and were a bit confusing," Psaki says. The USA's easing of travel restrictions follows the Council of the European Union's 30 August removal of the USA from its list of countries for which restrictions on non-essential travel should be lifted, 10 weeks after adding the country to the list. "The [Biden] administration’s decision to safely expand international travel to the United States is welcome news for our customers and United is ready to implement these new requirements," United Airlines stated on 20 September in response the news of the USA's easing of inbound international travel restrictions. US and European carriers throughout the summer months have been eagerly awaiting just such an announcement. Canada in September also began lifting restrictions on non-essential travel for people who are fully vaccinated. The White House on 26 July had said that the USA would keep Covid-19 travel restrictions in place for arrivals from the UK and the European Union, despite Europe having better success than the USA at both vaccinating its overall population and in battling the rise in infections caused by the delta variant of Covid-19. A few weeks earlier, on 15 July, US president Joe Biden said during a press conference that his Covid-19 advisers were assessing “how soon we can lift the ban" on non-essential travellers from Europe "within the next several days”.

The Civil Aviation Authority of Vietnam is proposing to lift a ban on Boeing 737 Max aircraft operations to and from the country. Based on the evaluation of other aviation authorities and the "safety index of the Boeing 737 Max aircraft after being licensed to operate again", the CAAV has asked that the transport ministry allow it to "carry out the necessary procedures" to resume operations and to recertify the aircraft type in Vietnam, it says in a statement issued today. The CAAV says it has been working with Boeing on the resumption of Max operations in Vietnam. Data shows that none of the Vietnamese airlines currently operate 737 Max jets, although VietJet has orders for 200. In April, Vietnam's transport ministry certified the Max for airspace transit. Then, the ministry had requested that CAAV monitor Russia, Australia and China's aviation authorities, with the CAAV saying it would propose the lifting of the ban once those countries allowed the Max to operate. Australia's Civil Aviation Safety Authority lifted its suspension in February. China and Russia have yet to certify the type for operations. In Asia-Pacific, Japan, India, Malaysia and Singapore have allowed Max operations to resume. CAAV says in its statement that according to updated information from Boeing, 178 of 195 aviation authorities around the world have lifted the ban on operations of the type. "The aviation authorities of China and Indonesia are expected to lift the ban [on the 737 Max] this September," the regulator states. The 737 Max was grounded in March 2019, following two fatal crashes within six months. FAA lifted its grounding order in November 2020 while EASA gave its formal approval in January.

In October 2021, the UK government plans to ease travel rules for people who are fully vaccinated against Covid-19, merging its travel warnings into a single "red list" of nations deemed to present a high risk of infection and terminating its moderate-risk "amber list". As a first step, the UK will on 22 September remove several nations from the red list: Turkey, Pakistan, the Maldives, Egypt, Sri Lanka, Oman, Bangladesh and Kenya. "As global vaccination efforts continue to accelerate and more people gain protection from this dreadful disease, it is right that our rules and regulations keep pace," states UK transport secretary Grant Shapps. As of 4 October, fully vaccinated travellers will no longer have to take a Covid-19 test before flying to the UK from a non-red-list nation. From the end of October, such travellers will have the option of taking less expensive lateral flow tests, rather than PCR tests, on day two after arrival.
