Air France-KLM announced Wednesday the "definitive end" of operations of the world's biggest commercial airliner, the A380, owing to the devastating coronavirus impact on air travel.

As the pandemic has slashed all travel and eliminated demand for huge planes, the airline said it would switch to a newer generation of aircraft that included smaller Airbus A350 and Boeing 787 jets.

"In the context of the current COVID-19 crisis and its impact on anticipated activity levels, the Air France-KLM Group announces today the definitive end of Air France Airbus A380 operations," a statement said. "Initially scheduled by the end of 2022," the move should make the group's fleet of planes "more competitive, by continuing its transformation with more modern, high-performance aircraft with a significantly reduced environmental footprint," it added. The "phase-out" is expected to cost Air France-KLM 500 million euros ($550 million), it added.
