About Air India

Air India is India's legacy national carrier — the flag-bearer that's been connecting the subcontinent to the world for decades. With 286 non-stop routes across 87 airports, this isn't a budget operation or a regional hopper. It's a full-service airline built around a massive domestic spine, with long-haul reach into the US, UK, the Gulf, and Europe. Delhi's Indira Gandhi International (DEL) is the real engine here, running 79 routes on its own. If you're flying to or through India, Air India is probably already on your shortlist whether you planned it or not.

Why fly Air India?

The honest answer? Reach. If you need to get into India specifically — not just a nearby hub — Air India's 213 India routes mean you've got options that other carriers simply can't match. I've personally found that routing through DEL opens up connections that would take forever on a one-stop-then-another itinerary with a European carrier. The long-haul routes are worth knowing about too. That Kolkata to San Francisco run (CCU-SFO) clocks in at 12,578 km — one of the longest single hops you'll find anywhere. For travelers in eastern India heading stateside, that's a genuinely useful option that skips an extra transit entirely. Price-wise, Air India tends to sit competitively on India routes, especially when demand spikes around Diwali or summer holidays when every other airline charges accordingly.

Tips for booking Air India

Book directly through Air India's site and double-check your baggage allowance before you assume — it varies more than you'd expect between fare classes and routes. DEL is your best connecting hub by far; BOM (Mumbai) works too with 45 routes, but if you're transiting, Delhi gives you the most onward flexibility. First-timers should know that Air India's service quality can be inconsistent — some flights feel genuinely polished, others less so. Set expectations accordingly rather than assuming business and economy feel identical across the network. And check whether your specific route falls under a codeshare, because that can affect everything from seat selection to how you handle disruptions.
