  • Represented Avior Airlines C.A. in the U.S. District Court for the Southern District of Florida in defense of a class action lawsuit filed by five South Florida law firms on behalf of the plaintiffs seeking well over $20 million against our client, a private commercial Venezuelan airline with flights between Miami and Venezuela. The plaintiffs alleged a breach of contract claim over an $80 “exit fee” alleging the fee was wrongfully charged to tens of thousands of passengers that travelled from Miami International Airport to Venezuela on Avior flights over a period of at least five years. After nearly two years of litigation, the court granted our client’s motion to dismiss the entire lawsuit with prejudice.

After five years of litigation, all of the plaintiffs’ claims were defeated and our client prevailed on all of its counterclaims.
