US transport authorities announced Monday they will allow a total of four weekly round-trip flights by Chinese airlines providing passenger air services between the two nations, which is a modification of the Trump administration's previous policy of banning Chinese airlines. 

The move, deemed a gesture of goodwill from both sides, will ramp up the resumption of flights connecting the world's two largest economies, industry analysts said.

The US on June 3 issued a ban on Chinese airlines, a move that cast a shadow over the resumption of bilateral air flights and put pressure on US airlines too. Global airlines have taken a severe hit from the COVID19 pandemic and are eagerly looking to restart flight. 

"The US Department of Transportation's modification of its restrictions was an active response to US airlines' demands to resume flights to China," Qi Qi, an independent market analyst, told the Global Times on Tuesday.

China on June 4 announced plans to loosen international air flight restrictions by allowing all qualified foreign airlines to resume services to China from June 8. 

Unlike the US' back-and-forth decisions on international flights, China's plan was based on thorough assessments, highlighting its sincerity in resuming safe aviation connections with the world. China's plan applied to all foreign airlines. Claims by some Western media outlets declaring it a response to the US ban lacked common sense, Qi noted. 

US airlines can resume services to China so long as they guarantee safety and take precautionary measures, including collecting all passengers' health information and requiring nucleic acid tests, Qi said.

According to media reports, Shanghai will accept flights from US-owned airlines, and China will also allow four weekly round-trip flights from US carriers.

Two US airlines - United Airlines and Delta Air Lines - have received access confirmation letters from Shanghai airports to resume flights to Shanghai, reports said. 

"We are pleased to be reentering the China market," said Delta in a statement sent to the Global Times on Tuesday.

Delta will resume weekly passenger flight to Shanghai from Seattle next week via Seoul, as well as another weekly flight from Detroit in July, the statement said.

United Airlines has also received an access confirmation letter from Shanghai airports, allowing it to resume two weekly flights to Shanghai, according to reports. The final schedule has not been fully disclosed.

All travelers from overseas are still required to complete 14 days of quarantine after arrival, according to a statement sent to the Global Times by the Shanghai Airport Authority on Tuesday.

Airlines from the Chinese mainland including Air China, China Eastern Airlines, China Southern Airlines and Xiamen Airlines are currently operating flights to and from the US.

An insider with China Eastern Airlines revealed to the Global Times on Tuesday that the airline has filed an application with the US transport department for flights between the two nations, noting that the application needs to be submitted 30 days ahead of schedule in accordance with US requirements as well as China's newly instituted "circuit breaker" rules for international flights as part of the nation's antivirus efforts.
