Being a new member in the European Union, I'm not surprised Czech Republic's flag carrier is slowly moving to an all Airbus fleet as most other European airlines fly/have flown at least one Airbus type(the only exception is Malev, Hungary is now part of the European Union and the flag carrier has never had any Airbus in its fleet). However the 4 A310's they operate on long haul flights can very well be replaced with B787's early next decade.
Checo77 must know.
This is the first picture of a CSA A320 on airliners.net
