MADRID, Feb 24 (Reuters) - Spanish airport operator Aena said on Wednesday it booked a loss in 2020 after air traffic around the world plummeted because of the travel restrictions imposed to curb the COVID-19 pandemic.

Aena reported a net loss of 127 million euros ($154.34 million) in 2020 compared with a net profit of 1.44 billion euros a year earlier as passenger traffic dived about 70%, the company said on Thursday.

Overall revenues fell about 50% to 2.27 billion euros, the company said.

In the short term, Aena does not see any recovery, yet. "In the current circumstances, it is not possible to anticipate at what moment the recovery may start," it said in a statement.

The company has kept its airport fees unchanged for 2021.
