President and CEO Luis Maroto says: "In January, the resurgence of the pandemic brought new movement restrictions in many parts of the world.
"However, as vaccination programs gathered pace in certain regions throughout the quarter, we saw an uptick in air bookings and passengers boarded in March. Volume-wise it was the best performing month since February 2020. Into April, we have seen further improvement.
“Despite this, we remain cautious as we focus on delivering planned efficiencies and our on-going commercial efforts."
