The traveler experience at Delhi's Indira Gandhi International Airport is getting better. Baggage transfer from T3 to T1 is being tested by DIAL. Passengers on connecting flights will benefit from this. They won't have to transport their luggage from one terminal to another. T2 will be closed for maintenance for a while. Beginning on April 15, flights will switch to T1. DIAL pledges to transfer from T1 to T3 for 120 minutes.
