I have a question regarding asking for a refund if fares go lower with a flight you have schedueled with SW. First, for those of you who received credit card refunds or SW credit, does it have to be on the exact same flight that the price went lower through DING or anything else. I am asking because my flight now shows unavailable. So if I call will they say that the flight is full so no refund will be given. Also, does it have to be the exact flight, time ect and can you only do it once? Right now the flights are $10.00 cheaper than what I paid but not near as low as they could be. Should I wait because they will only do it once? TIA!
