Royal Caribbean Cruises states in its footnotes that payments received in advance for passenger cruises represent unearned revenue and are initially recorded as customer deposit liabilities on its balance sheet. Customer deposits are subsequently recognized as passenger ticket revenue upon completion of the voyage. Customer deposits at the end of 2009 were $1,060 and at the end of 2010 were $1,283. Passenger cruise revenue for 2010 totaled $4,909. Assume all cruises are paid in full before the voyage. How much cash did Royal Caribbean collect in 2010 from customers for cruise tickets?
