I have been waiting for a refund since April on a fare that allowed a cash refund but also where they cancelled the flights. Have been 2 rounds through with the DOT and they keep saying they will refund then dont. These folks are the worst, don't book until you think there is 100% chance you can fly it.
That said, the fare is amazing. If I knew there would be a fare like this I might have just taken a voucher + 20% that they offered.
