Delhi International Airport Limited (DIAL) has revealed its master plan to start the process of airport expansion. Construction work at Delhi airport is likely to commence by March 2018. Starting October 1, 2017, one-third of IndiGo, GoAir and SpiceJet passengers will be shifted to flights operated from Terminal 2 (T2). The airlines had been asked to submit the details of flights they plan to shift to T2 by end-August 2017. Thereafter, the master plan will be implemented in three modular phases – Phase 3A (2018-21), Phase 3B (2021-25) and Phase 4 (2026 onwards). The expansion process will commence from Terminal 1 (T1) during which its capacity will be augmented from 20 million
passengers per annum (mppa) to 40 mppa and will have 22 aerobridges. Further, two terminals – T1 D and T1 C – will be merged and expanded to accommodate 40 mppa. Once the expansion work of T1 is complete, T2 will be demolished to build a fourth runway which is slated for completion by 2021. Post-2026, Delhi airport will have three operational terminals and four operational runways and is expected to cater to 115 mppa.
