The European Commission announced its intention to return to the longstanding 80-20 slot use rule, which requires airlines to operate at least 80% of every planned slot sequence.
While airlines are keen to restart services, Iata said the "failure of several key airports to accommodate demand, coupled with increasing air traffic control delays," means a premature return to the 80-20 rule could lead to further passenger disruption.
"The chaos we have seen at certain airports this summer has occurred with a slot use threshold of 64%," said Iata’s director general Willie Walsh.
