We flew last Saturday and the flight was delayed a total of 89 minutes. First they said the FAs were delayed, then they closed the door and before pushback, the pilot comes on and says they are getting a full lavatory indicator. Now they have to pump the rear bathrooms. Better than the alternative, I guess Anyway, I called SWA today and complained and they gave us each $50 in vouchers. It pays to complain and it didn't take much complaining!
