Significant flight cancellations at TUIfly have affected many airberlin flights which are operated by TUIfly under a wet-lease agreement.
EAP includes airberlin, Etihad Airways, Alitalia, Air Serbia, Air Seychelles, Jet Airways and Etihad Regional.
Etihad Airways has provided an Airbus A340 aircraft to airberlin from October 7, while Alitalia has already provided airberlin with one Airbus A321 aircraft and is working to provide a second aircraft.
In addition, Air Serbia has provided airberlin with one Boeing 737 aircraft and is looking to provide a further two aircraft in the coming days.
Stefan Pichler, CEO of airberlin, said, "We are working hard to minimise the inconvenience to our customers and our EAP partners are rallying round to work with us in close harmony as one united team.”
