Mumbai
Chhatrapati Shivaji Maharaj International Airport (BOM) sends its Bengaluru traffic out in two thick bands — an early bank for people who intend to be sitting in a Bengaluru meeting by mid-morning, and an evening bank for the ones flying home after it. Mumbai works from two terminals, T1 and T2, and which one you leave from depends on the carrier you booked, so read the terminal off the e-ticket instead of assuming. The upside of a corridor this dense is that a sold-out flight is rarely the end of the story: with IndiGo alone running about 25 of the day’s BOM–BLR departures, there is usually another aircraft behind it — at a different price.
