Valuewings

Valuewings Ltd is a European ultra low cost airline, headquartered in Bucharest, Romania. Valuewings operates flights under its own brand under two separate operating certificates, as a result of Brexit. Valuewings Ltd operates 'mainline' flights under its own brand between cities across Europe, with operating bases in Bucharest, Paris-Orly, Berlin Brandenburg, Lyon, Stuttgart, Rotterdam, Ljubljana, and Dublin. Valuewings UK Plc operates flights from its UK bases, with its local headquarters at London Stansted Airport. Additional flights operate from Liverpool, Leeds Bradford, and Prestwick Airport. 
Valuewings is highly criticized by the media for its 'predatory pricing', often offering travelers with fares starting at 4 EUR.
