A method and system may reduce latency and improve connectivity by performing offline authorization of products and services related to airline reservations. A server device may receive a request for a product or service related to an airline reservation from a user including payment information for the user and may transmit the payment information to a payment service provider for authorization. In response to identifying an outage at the payment service provider, the server device generates a temporary approval code indicative of a successful payment to prevent latency during the outage at the payment service provider and stores transaction data including a representation of the payment information for the user in an offline database. The server device proceeds as if payment was successful and provides an order confirmation message to the user's client device indicating that the product or service has been reserved for the user.
