Cash Refunds for Coronavirus Cancellations Act of 2020 This bill requires air carriers and ticket agents to offer full cash refunds for all cancelled tickets during the COVID-19 (i.e., coronavirus disease 2019) emergency period, regardless of whether the air carrier cancelled an entire flight or the passengers cancelled their individual tickets. The bill permits air carriers and tickets agents to offer alternative forms of compensation, including credit, or vouchers, provided that such offer is valid indefinitely and the offer includes a clear and conspicuous notice of the passenger's right to a cash refund. Additionally, the bill provides that passengers who received an alternative form of compensation prior to the enactment of this bill, but have not used it, may request a cash refund to replace the alternative compensation.
