On July 3, 2017 Flight #718 from MSY was scheduled for departure at 1:45 pm, then notice came that the flight would be delayed for an hour, until ultimately it was cancelled. We received notice at 3:31 pm that the flight would be rescheduled for the next day (flight #5718 at 10 am on July 4th). Due to the inconvenience, we were told that we would be receiving hotel vouchers. I spoke to the gentleman that gave us notice (I can't remember his name), but he stated that the vouchers could be used at any hotel within 50 miles of the airport. When I received my voucher, it had my name, Adrienne Nickerson, flight confirmation, #6WTZ6M, and the voucher was made out for $0.00. On the voucher, it reiterated that it would be good for use at a hotel within 50 miles. Myself, a young woman traveling alone, and a married couple to the shuttle to the Hilton Airport Hotel. We gave our vouchers to the receptionist and were allowed to check in for our one night stay. We checked in before 5:30pm. The voucher turned out to be of no good because I received a charge on my credit card in the amount of $143.44 for the Hilton Hotel Airport. I would like to be reimbursed as soon as possible.
