The IATA, which represents around 300 airlines accounting for 82 per cent of the global air traffic, measures passenger growth in terms of revenue passenger kilometers (RPKs), which is calculated by multiplying the number of passengers with the distance travelled by them.
"The experience of the domestic Russia and India markets currently sits in contrast with the outcomes elsewhere. Passenger volumes in domestic Russia fell by 15.4 per cent year-on-year in March, and by 11.8 per cent year-on-year in India; both represent relatively resilient outcomes," the IATA said in its statement on Wednesday.
"In annual terms, capacity increased in both markets this month (March). However, the COVID-19 outbreak began to impact these countries later than elsewhere and lockdown also lagged the experience of many other nations. As a result, the relative out-performance in traffic volumes may not be sustained in April, with larger declines still to come," it stated.
