Grupo Viva Aerobus SAB filed for what would be Mexico's second initial public offering of shares by an airline since September as passenger traffic sets annual records. Interjet, Mexico's second-biggest carrier in 2012, may sell shares this year, Executive President Miguel Aleman Magnani said in November. Photographer: Susana Gonzalez/Bloomberg via Getty Images
