T2 airport is silence airport, no announcement so be proactive and get your baggage checked in on time.
Like any airlines, Indigo is also good and definitely on top with rest in terms of timelines. No delays here.
Udaipur airport is 27 km from the main city so be prepared to shell off some money on Cab/Taxi. I preferred to take govt pre-paid taxi from the airport which costed 750 to fateh sagar lake (others take 1200-1400).
