Mexicana filed for insolvency proceedings in Mexico and bankruptcy protection in the United States, but said it would "continue to render services normally while it restructures its liabilities and brings its costs into line with market conditions." The airline said it made "minor adjustments to its international flight schedules," including frequency cuts and some service suspension. Several nonstop routes to the United States have been replaced with connecting service through Mexico City. In an unrelated development, the airline also no longer can carry the code of partner American Airlines, following a decision by U.S. regulators related to Mexico's civil aviationauthority.
