DEAR TRAVEL TROUBLESHOOTER: Air Canada destroyed my Rimowa suitcase on a recent flight from Toronto to San Francisco. The airline instructed me to send the suitcase to a repair agent in Texas. The agent declared the suitcase unrepairable, despite the fact that they have no contract with Rimowa and no product expertise in this brand. Christopher Elliott, the Travel Troubleshooter Air Canada then offered me a choice of inferior replacement bags, which I declined, and recently sent me a $230 check in proposed compensation.
