Passenger traffic continues to be adversely affected by the impact of Hurricane Wilma which hit the Yucatan Peninsula in October 2005.





Ongoing public demonstrations in the city of Oaxaca have adversely affected tourism in the area and have led to the cancellation of 53 flights to the Oaxaca airport originally scheduled for the month of September.  The protests began as a teachers strike in May but have grown into more widespread general unrest against the Oaxaca state government.  Protesters have threatened to close the airport and block regional highways, and the US State Department recently issued an advisory regarding travel to Oaxaca.  We are unable at this time to predict whether or how the conflict will be resolved, or how the ongoing demonstrations may affect our operations.
