Can I use my return ticket if I did not fly the one way?

The flights or sections that make up the itinerary of your ticket must be flown in the order indicated. Otherwise, the itinerary is canceled in its entirety.

However, in Brazil, Colombia, Germany or Italy exceptions can be made under some conditions. In Peru, Argentina, Chile and Ecuador there are also exceptions, but only for 100% national sections.

The rest of the countries are subject to the conditions of the ticket fare.
