Do not mix up
1. "Eurowings Europe" EWE (PMI, VIE, SZG bases)
2. Eurowings Germany EWG (bases in Germany)
3. Germanwings (Germany, was crewed by Lufthansa crew who now return to mainline with seniority, will fade out eventually)
-different contracts and terms
-different bases
-different requirements for hours, school and German language
For EWG you have to speak conversational German
afaik. If you can learn that in 2 months? Maybe.
And why would you need a visa, coming from the EU being EU citizen.
