    About the FrankfurtDelhi route

    The FRADEL route covers approximately 5,960 km great-circle distance between Frankfurt Airport in Germany and Indira Gandhi International in India. In economy class, each passenger is responsible for approximately 536 kg CO₂ per flight direction, or 1,072 kg for a round trip — calculated using the ICAO Carbon Emissions Calculator v13.1 methodology with fleet-average aircraft and typical load factors.

    Business class passengers on the same route emit approximately 1,876 kg CO₂ per direction — roughly 3.5× more than economy — due to the larger floor area allocated to each business class seat. The climate impact is further amplified by a Radiative Forcing Index (RFI) of 1.9×, which accounts for non-CO₂ effects of aviation at cruising altitude including contrail formation and NOₓ emissions.
