I bought a plane ticket on Southwest airlines. In case that it's delayed (for whatever reason), do I have the right to forfeit my ticket and get the fare refunded? Southwest's contract of carriage says this:
Delays or Involuntary Cancellations. If a Passenger’s scheduled transportation is cancelled, terminated, or delayed before the Passenger has reached his final destination as a result of a flight cancellation, Carrier-caused missed connection, flight delay, or omission of a scheduled stop, Carrier will either transport the Passenger at no additional charge on another of Carrier’s flights, refund the fare for the unused transportation, or provide a credit for such amount toward the purchase of future travel.
But what does "Carrier-caused" mean? Can I refund the ticket regardless of if the delay is caused by mechanical or weather issues?
