Csa

CSA Czech Airlines (IATA: OK) is a Czech, Prague-based airline brand historically tied to Václav Havel Airport Prague; its former csa.cz site now redirects travelers to Smartwings. For trip planning, treat OK-coded/CSA-branded travel as part of the Smartwings environment rather than as a current SkyTeam proposition: published references show Czech Airlines left SkyTeam, and OK Plus is a former frequent-flyer program rather than a current program to rely on for new crediting. The practical network is Prague-centered and short/medium-haul, with Smartwings publishing scheduled services, charter flights and private flights, plus a destinations list focused on European leisure and city routes with some nearby non-European points. Before booking or crediting, verify the operating carrier, ticket number/prefix and fare bundle, because baggage, seat selection, changes and refunds vary by package.
