I booked a flight on line with A Airlines, Rochester, NY to Fort Lauderdale, for $201. A week and a half later I checked the flight again on a whim. It showed the same flight and time at $111. I thought it was a typo. I called A A they also thought something was wrong, After taking my exact flight info, the nice lady came back with the $111 fare, go figure. I received the voucher for the difference last Saturday in the mail. I was totally surprised. Since I thought the already discounted fare was locked in no matter what.
