Interesting reading, not so much when it comes to the destinations and their schedules, but rather the framing: 'the Lufthansa group' and even 'lufthansa proper' are abundantly mentioned, with the flights merely 'operated by Eurowings'.
And in fact they are operated by Brussels Airlines.
SunExpress Germany plans to drop its long-haul routes in 2021, which are operated for Eurowings. The seven A330-200s will exit the fleet as a result, and maybe will be transferred to Lufthansa CityLine, who is expected to take six A330s soon.
'Eurowings Holidays' already exists for several years and it's not exactly a seperate brand. It's nothing more and nothing less as a sort of (online) touroperator, mainly based on EW's own flight network in combination with other partners that build up the holiday package offer that's being sold to customers. HLX Touristik is a new partner in that.
Just like you have 'easyJet Holidays', 'Holidays with Aer Lingus', 'Ryanair Holidays' (if it still exists?), 'Lufthansa Holidays', 'Swiss Holidays', etc, etc, etc.
The UFO union has called the cabin crew of Germanwings flight operations to a strike from 30 December 2019, 00:00 h, to Wednesday, 1 January 2020, 24:00 h. Eurowings is preparing a special flight schedule, which will be published on Saturday.
It should be noted that only 30 of the approximately 140 Eurowings aircraft are operated by Germanwings.
