About the Delhi → Bengaluru route
Delhi to Bengaluru is one of India's trunk routes — roughly 1,700 km, just over two hours in the air, and operated by everyone worth mentioning: IndiGo (6E), Air India (AI), SpiceJet (SG), and Air Asia India (IX). This isn't a leisure route in the traditional sense. You're mostly looking at IT professionals, startup founders, government contractors, and a fair number of people doing the family-visit shuffle between India's political capital and its tech capital. Flights run throughout the day in both directions, which means the 6 AM departures out of DEL are genuinely packed with people in collared shirts carrying laptop bags.
Why travel from Delhi to Bengaluru?
Bengaluru earns its reputation as India's tech hub honestly — Koramangala alone has more co-working spaces and pitch decks per square kilometre than most cities have office buildings. But that's not the whole story. The city sits at elevation (around 900 metres), which gives it a noticeably cooler climate than most of peninsular India, something Delhi residents in May genuinely appreciate. Beyond the tech campuses, there's the Lalbagh Botanical Garden, a serious craft beer scene that punches well above its weight nationally, and Bengaluru's own distinct South Indian food culture — set dosa and filter coffee that will reset your expectations permanently. Family ties between the two cities run deep as well, particularly among communities that relocated during the IT boom.

Practical tips for DEL → BLR
BLR's Kempegowda International Airport is well-organised but genuinely far from the city — budget 60 to 90 minutes to central areas like Indiranagar or MG Road even on a good traffic day. The Kia Shuttle bus is affordable and underused by travellers who don't know about it. Avoid January to March if you want lower fares; October and November are usually better value. If you're flying 6E or SG, check your baggage allowance before you pack — their base fares are carry-on only. No visa complications here (domestic route), and you won't need to change currency.
