Mexico's largest airline group, Aeromexico , will increase the frequency of flights on five of its main international routes, the company said Tuesday. On its European routes, Aeromexico will offer daily flights from Mexico City to Amsterdam and to London Heathrow - up from three and six flights per week, respectively. The carrier will increase its seat capacity to Madrid by 15 percent, for a total of 12 flights per week. Aeromexico also plans to increase its service to Asian destinations such as Shanghai by more than 65 percent. In South America, daily service to Santiago, Chile, will be added. The move contrasts with the biggest US airlines, which have been slowing growth plans for after the peak summer travel season. <br/>
