[...] the connecting flight from London to Baltimore was canceled because of a mechanical problem, and a day later I was rerouted to Washington Dulles International Airport. [...] British Airways had announced that it would refund the cost of transportation between Washington and Baltimore, if the receipt was forwarded to the customer-service department. [...] I submitted the receipt for $211, the cost of the taxi. No limit restriction on taxi fare had ever been mentioned — if it had, I would have tried to find alternative transportation. If British Airways promised it would cover your taxi fare, then it should have. Why wasn’t it?
