IndiGo Airlines (6E, Delhi International) appealed last week against the Delhi High Court ruling which confirmed that the Delhi International airport was at liberty to order the airline to partially relocate to another terminal due to congestion, The Hindustan Times reported.

Delhi's airport operator ordered IndiGo in October 2017 to relocate its flights out of the Indian capital to Mumbai International, Bengaluru International, and Kolkata from Terminal 1 to Terminal 2 due to the congestion of the former. The decision was supposed to enter into force on January 4, 2018. A similar order was given to GoAir (Mumbai International) and SpiceJet (SG, Delhi International).

The High Court ruling confirmed the airport operator's decision but extended the deadline for the airlines to partially relocate until February 15.

IndiGo argues in its appeal that a partial shift of operations to another terminal will constitute an obstacle to its transfer passengers, while the Delhi airport operator points out that without the partial relocation, Terminal 1 will soon be overcrowded.

Terminal 2 of the Delhi airport was opened in 1986 as an international facility but was closed following the opening of the new international Terminal 3 in 2010. It was then partially reopened in October 2017 as a domestic terminal. According to the ch-aviation schedules module, GoAir is currently the sole airline at Terminal 2 as neither Indigo nor SpiceJet have relocated to the facility yet.

IndiGo currently primarily uses the domestic Terminal 1D at Delhi, while its international services to Doha Hamad International, Dubai International, and Kathmandu are operated from the international Terminal 3.
