A jetliner aborted a landing in Mexico City because of another plane on the runway, an airline said Thursday (Friday in Manila) — the second such incident within days at the congested airport. Aeromexico said flight AM762 had performed a go-around on Wednesday evening because another plane was still on the runway at Benito Juarez International Airport, the busiest in Latin America. It did not say how many passengers were on the plane, which according to flight tracking websites was a 160-seat Boeing 737-800 coming from Colombia. The transport ministry described the go-around as a normal procedure that “did not represent any risk.” A similar incident happened on Saturday when a plane operated by Mexican carrier Volaris aborted its approach to avoid hitting a plane taxiing on the runway. Air safety concerns have emerged since Mexico City’s airspace was reconfigured following the opening of a second international airport, Felipe Angeles, on March 21.
