I just got off the phone with SWA a few moments ago and they told me they do not offer cash refunds until after the trip has been taken, AND as long as it's the same type of ticket change AND same exact flight. You then submit a refund request in writing or accept the difference as a credit for future travel.
So if you switch from Internet Special to Refundable Anytime or Discount to Ding!, then you cannot get a refund even if its the same flight # because it's a different ticket type.
I bought internet special tickets for $99
I saw the price drop to $63 FOR THE SAME FLIGHT NUMBERS
I applied to change my flights
Once I fly, I'll submit for refund.
Per SWA website:
"Refunds - Any change to this itinerary may result in a fare increase. To make application for a refund of any unused air fare, please write Southwest Airlines Refunds Department - 6RF, P.O. Box 36611, Dallas, TX 75235-1611. Refund requests must include a copy of this document and/or your confirmation number, date of travel and flight number, and all credit card billing information including the amount and purchase reference numbers."
