Wealthy Czechs were accustomed to vacationing on the Adriatic coast from Austro-Hungarian times, and ČSA ran an Adriatic Express service to Zagreb and Sušak, near Rijeka. It was reported that the Czech airline bought this amphibian 'so that the harbour at Sušak may be used when the hill-surrounded aerodrome cannot be reached in bad weather.' Later reports say it served on a coastal extension of the route from Sušak to Split and sometimes Dubrovnik, in 1936-1937. Earlier, OK-BAK was owned by the Bata family, who may have used it in the Adriatic too. The hull survives in Kbely.

The Saro A.19 Cloud was an enlarged derivative of the A.17 Cutty Sark. This airframe, powered by Armstrong Siddeley Serval III engines, is seen during a European sales tour. It was sold as OK-BAK to the Bata family and later to ČSA. The Czechoslovak airline used it on its Adriatic Express service from Sušak near Rijeka to Split and sometimes Dubrovnik. The hull is preserved at Kbely. Photo from: Amsterdam City Archives
