Mexico air travel slump worsens in May, international traffic down
International passenger traffic plunged at all three listed Mexican airport groups in May, with Cancún down 11.1% and Puerto Vallarta off 26.5%, putting fresh pressure on airport and airline valuations as investors weigh weaker foreign flows, rising fuel costs, and engine shortages; Volaris and Aeroméxico shares have lagged U.S. peers, falling 2.3% and 23.2% this year, respectively.
