New Delhi, Jul 29 (IANS): Global air passenger traffic will not return to pre-COVID-19 levels until 2024, a year later than previously projected, the International Air Transport Association (IATA) said on Tuesday.

The updated global passenger forecast, released by IATA on Tuesday, showed that the recovery in traffic has been slower than had been expected.

"In the base case scenario: Global passenger traffic will not return to pre-COVID-19 levels until 2024, a year later than previously projected," the association said in a statement.

"The recovery in short-haul travel is still expected to happen faster than for long haul travel. As a result, passenger numbers will recover faster than traffic measured in RPKs. Recovery to pre-COVID-19 levels, however, will also slide by a year from 2022 to 2023."

As per IATA's forecast, for 2020, global passenger numbers are expected to decline by 55 percent compared to 2019, worsening from the April forecast of 46 percent.

"June 2020 passenger traffic foreshadowed the slower-than-expected recovery," the statement said.

"Traffic, measured in RPK, fell 86.5 percent compared to the year-ago period. That is only slightly improved from a 91 percent contraction in May. This was driven by rising demand in domestic markets, particularly China. The June load factor set an all-time low for the month at 57.6 percent."

IATA cited slow virus containment in the US and developing economies, reduced corporate travel and weak consumer confidence.

"Owing to these factors, IATA's revised baseline forecast is for global enplanements to fall 55 percent in 2020 compared to 2019," the statement said.

"Passenger numbers are expected to rise 62 percent in 2021 of the depressed 2020 base, but still will be down almost 30 percent compared to 2019. A full recovery to 2019 levels is not expected until 2023, one year later than previously forecast."
