BER – Germany's greenest airport


Two production processes with potential for optimization

1. Almost simultaneous flights of (competing) airlines from A to B.


Using the Berlin-Stuttgart route (before Corona), we have shown that with the same number of seats, instead of 15 daily flights (easyJet and Eurowings), only 11 flights are needed. Both airlines share one aircraft with securing the same transport line (number of seats). 


A319neo   124 seats   –   2,82 l/100 km/seat
A321neo   192 seats   –    2,19 l/100 km/seat

Turn 3 into 2 flights

  • Fuel savings: up to 20%.
  • CO₂ emissions (analogue to fuel): up to 20% lower

Instead of 7 or 8 daily flights of their airline, travellers now have 11. The travellers will have the choice between 11 daily flights.

2. shair production scenario with fuel savings and CO₂ reduction.
Game Changer: Direct non-stop flights instead of connecting flights

Scenario: Analysis using the example of the flight connection between Prague and Qingdao

transferable in principle to Berlin – Shanghai 


reduces fuel consumption for airlines        

reduces CO₂ emissions and can help to get even closer to the 1.5 degree target
makes flying more comfortable and faster for passengers

 Three essential framework conditions for shair

 1. Presentation of an economically and infrastructurally strong catchment area using the 
      example of Berlin-Brandenburg.

Rail travel times to BER (ICE, EC, IC) within the catchment area

With regard to the interlocking of flights and trains, easyJet concluded a corresponding agreement with Deutsche Bahn last year. Among other things, this also includes the domestic German connections listed here. As part of the project work, it is to be examined whether the agreements can also be extended to Poland if travel times are attractive. 

More details on the agreement, including the easyJet/Deutsche Bahn network, can be found at the following link: (This is only in German.)

In addition, other multimodal options, e.g. long-distance bus providers, e-taxis and e-rental cars, are to be evaluated with regard to environmental compatibility, speed, comfort and cost/price and selected as "system-relevant stakeholders" for the respective catchment area.  

The catchment area of Paris CDG is similarly convenient.  Comparable options in Asia and North America are also being considered to realise a first platform for greener flying (intercontinental) supported by shair. To speed up implementation existing infrastructure should be used to a large extent. 

2. Variable segmentation of the aircraft cabin

A core element of shair is therefore the visual segmentation of the aircraft cabin along the corporate and product features of the respective customer airlines. A cabin configuration management system will enables the variable and individually adjustable design of the aircraft cabin for each single flight. 

A significant differentiating feature is the corporate colour of the respective airlines, which is used for lighting elements in the cabin. 

This can be adjusted from one flight to the following flight according to the specific demand constellation "at the push of a digital button". 

Examples of different segmentation:

3. Use of artificial intelligence

  • Identification of appropriate consolidation flights, e.g. interrelated with our US patent; its headline is "fuel savings".


  • Identification of "new" non-stop direct flight connections 
  • In the case of "new" direct flights, analysis of the customer mix by region of origin
  • For the latter, also conclusions on demand mix according to price elasticity of customers.
     To what extent are customers willing to pay a higher price for a greener product?

  • "Area2Area" analyses for multimodal production, capacity and price measurement
