What is the strategy people are following for Southwest given the flight credit expiration policy? I assume that everyone is booking Choice tickets <$109 in order to get the 12 month flight credit expiration and transferability vs. the 6 months for the Basic fares. It does make me think that I should delay getting the credits until later in the year to extend the credit duration, but on the other hand, there's always the risk that the loophole gets closed on us.
