Czech Airlines (CSA) uses Airbus 300 on there long haul flight from Prague to N. America and the Far East. They are 15 years old so they are begining to look a littel weathered. As for there service, I have flown in there economy class as well as there business. Business is nothing to write home about. wider seats, bottled beer a good food but nothing special. Economy a little cramped, stale & dry air in the cabin and no tv's in the seats.
