The national tourism chamber says it is upset because the Avianca-Taca airline is canceling five direct flights to Costa Rica.
The flights are from Guayaquil, Colombia, Quito, Ecuador, Los Angeles and New York in the United States and Havana in Cuba.
The chamber, the Cámara Nacional de Turismo , said that as a national flag carrier, the line should have more respect for Costa Rica.
The change means a reduction each month of from 180 to 220 flights, said the chamber and from 6,000 to 8,000 passengers a month.
The airline still is servicing Costa Rica, but in some cases passengers will have to take flights with intermediate stops.
