PRAGUE, Czech ******** — Flight attendants at the Czech national carrier CSA will go on a three-day ****** over low pay.

The cabin crew union says the ****** begins Wednesday. It did not say, however, how many flight attendants are expected to participate in the ****** and how many flights will be affected.

CSA said in a statement Monday that it considers the ****** illegal and is taking measures to prevent flight cancellations. Details of the plan were not given.

As a member of the SkyTeam alliance, CSA provides flights to 48 destinations in 24 countries this summer.

The Czech government sold a 44 per cent stake in the ******* to Korea Air in 2013 as it sought a strategic partner for CSA. The Czech state still owns almost 20 per cent.
