CSA Czech Airlines (OK, Prague Václav Havel) has wet-leased two B737-800s, OK-TVO (msn 32360) and OK-TVT (msn 39394), from fellow Czech operator Travel Service Airlines (Prague Václav Havel). Local aviation media portal, planes.cz, reports the aircraft are being used on flights to Madrid Barajas, Tel Aviv Ben Gurion, Barcelona El Prat, Paris CDG, and Copenhagen Kastrup.

According to the report, CSA's outsourcing its regional narrowbody needs to Travel Service proved cheaper than operating the routes using its own inhouse fleet of nine A319-100s and six A320-200s, the latter of which it intends to dispose of entirely.
