How to calculate the time of negative proof of nucleic acid by plane? Is 48 hours enough? -Today's hot spot

Nowadays, due to the epidemic situation, nucleic acid proof has also become the most important certificate for our travel. Recently, it was reported on the Internet that a passenger of China Eastern Airlines was refused boarding for three minutes because of a 48-hour nucleic acid report. So, what is the time requirement for negative nucleic acid certification by plane? How exactly is it worked out? Is 48 hours enough? Let's take a closer look.

"Passengers must have a 48-hour negative nucleic acid test certificate when boarding the plane. 48 hours is from the sampling time of passenger nucleic acid detection to the landing time of the flight. Because the flight delay caused the nucleic acid detection time to exceed 48 hours, it was impossible to board the plane. " The customer service staff of China Eastern Airlines explained that the calculation of the 48-hour nucleic acid test negative certificate required by passengers in Beijing and Shanghai is from passenger sampling to flight landing, other local policies and specific flight requirements. Passengers can consult the customer service staff of China Eastern Airlines before traveling.

"Passengers who plan to enter (return to) Chengdu in Shanghai, please make preparations in advance, and be sure to understand the local epidemic prevention policies in advance before traveling, and subject to the latest prevention and control requirements issued by relevant departments." On June 14, the website of China Eastern Airlines released the third warm reminder this year to remind passengers from Shanghai to Chengdu to pay attention to the latest epidemic prevention and control requirements.

From June 10, 2022, all passengers flying to Chengdu (except entry personnel) must provide negative nucleic acid test certificate, check health code and communication itinerary card within 48 hours before boarding. However, the reporter noticed that the announcement did not explain the criteria for determining the effective start time and end time of negative proof of nucleic acid testing.
