Aeromar Airlines (México City International) has withdrawn its fleet of three CRJ200s from revenue service citing their exorbitant maintenance costs. Airline sources who spoke to El Punto Critico on condition of anonymity said the jets would be replaced with a pair of ATR42-600s.

"Despite the [CRJ] flights seeing more than 75% occupancy, their maintenance costs proved very expensive. So we're going to get rid of them and want to modernize the fleet with two ATR42-600s," the source said.

According to the ch-aviation aircraft database, the CRJs were last used on flights between México City International and Piedras Negras.

As an additional cost-cutting measure, the airline has also terminated its flights to Austin-Bergstrom International as well as its San Luis Potosí to McAllen in the United States citing low occupancy rates.

Aeromar continues to operate an all ATR - Avions de Transport Régional fleet of four ATR42-320s, ten ATR42-500s (on its own flights), and two ATR72-600s (in service for Aeroméxico Express).
