Rheiner is a company founded in Frankfurt in July 2014 that specializes in airport catering and handling services with its own staff.

Rheiner's adventure, which began in 2014 with the provision of catering in the Skayteam lounges at the German airports of Frankfurt, Stuttgart and Munich, quickly developed into a business lounge business.

From 2019, nine lounges will be served in Germany, Frankfurt (2), Stuttgart, Munich, Berlin, Leipzig, Bremen, Zurich in Switzerland and Copenhagen in Denmark. During this period, Skyteam worked with the Airline Association, Air France and the TAV Group.

After the pandemic, Rheiner continues its core business of providing airport catering and handling services with its own staff and also offers catering services with its own staff to other customers outside the airport. In addition, Rheiner is involved in a restaurant business and the aim is to continue to grow in the catering sector.
