If a travel website erroneously lists a low price for air fare and you book a trip, can you hold the airlines to the low fare? As the ContractsProf Blog recently explained, it depends, but you might be able to. The ContractsProf’s post discusses a situation where the published fare was a fraction of the going rate for a round trip from San Francisco to Palau. Was it a case of a unilateral mistake? It depends on whether the customer should have known that the fare was in fact too good to be true.
