Jet Blue, a major airline, receives payment from customers either by credit card, such as Visa, or American Express. For example, let us say that John Brown, the customer, booked a flight for $600 using Visa. The credit card company (Visa) will pay the airline for the ticket shortly after the flight is booked, but it might take several weeks before John Brown actually takes the flight. When would Jet Blue actually record the revenue? Prepare the journal entry for Jet Blue for the receipt of the payment of the fight and the adjusting entry when the flight is completed. (Prepare two journal entries.) If the ticket was nonrefundable, and John did not take the flight at all, then when does Jet Blue record the revenue? Answer the four questions.
