International travel is likely to remain subdued until the end of 2021 as countries reintroduce tough lockdown measures.
That's according to Emirates CEO Tim Clark:
''I think probably we're going to see some difficulties, we're not going to see capacity return to the levels I've hoped in July and August, I think that maybe in the last quarter of this year."
Clark's comments at Wednesday's (February 10) virtual summit by aviation consultancy CAPA represent a pessimistic turn.
Last month he told Reuters he did not believe the recovery would be further impacted by a new wave of infections and restrictions.
Meantime, easyJet CEO Johan Lundgren has called on Britain to set out how it will ease travel restrictions.
On Wednesday he said there was strong demand for leisure travel, but the success of what could be a make-or-break summer for European airlines depends on the effectiveness of vaccines.
Britons already face a holiday ban under current lockdown rules.
Earlier on Wednesday, the country's transport minister told people not to book trips abroad or at home for the summer.
EasyJet plans to fly no more than 10% of 2019's capacity in January-March, down from 18% in September-December.
