Kolkata to Mumbai is 2,000 km — one of India's longest domestic routes. The flight takes 2.5 hours. The train? 33 hours. This isn't even a question.
Comparison
Verdict
- ✈️ Fly. Absolutely. You save 30+ hours. Even at ₹8,000, that's ₹260/hour saved
- 🚂 Train? Only if you're on a Bharat Darshan package tour
- 💡 Tip: Book 2-3 weeks early for ₹3,500 fares. IndiGo and Air India compete hard
