Airlines body IATA said it was monitoring the situation.

About 1.4 million passenger seats are flow into or out of
Mexico each week, according to data supplied to Reuters.

Among foreign airlines, those immediately at risk from any
travel slowdown to and from Mexico are the major U.S. carriers
followed by Canada and Europe, with Asia lagging well behind.

Below is a breakdown of weekly airliner capacity into and
out of Mexico, ranked by the number of seats on sale.

The data was supplied to Reuters by Innovata, a British
company which tracks airline schedules on behalf of IATA.

The first column of data shows the number of one-way flights
operated each week to or from Mexico (a round-trip counts as two
trips). Column two shows the number of seats on sale each week.

(Note: 44 airlines operate internationally to/from Mexico.
The list has been edited to exclude some regional operators.)
