Route Briefing: Singapore to Delhi
Five and a half hours is a remarkably short hop between two of Asia's most iconic cities, and that directness is part of what makes the Singapore to Delhi route so compelling. IndiGo, Air India, and Singapore Airlines all serve this corridor year-round, giving you genuine flexibility on timing and comfort level. If you can snag a roundtrip under $350, you're doing well — standard fares tend to climb above $550, so hunting for that sweet spot is worth the effort. Book six to eight weeks out for the best chance at those lower fares, and be strategic around Indian festival periods: Diwali and Holi send prices surging as the entire subcontinent seems to be on the move.
Delhi rewards the curious traveller in ways that few cities can match. This is a place where Mughal grandeur sits shoulder to shoulder with colonial-era architecture and the relentless energy of a modern megacity. The Red Fort and Jama Masjid in Old Delhi are genuinely awe-inspiring, and wandering the lanes of Chandni Chowk — one of the oldest and busiest markets in Asia — is an experience that engages every single sense simultaneously. On the other end of the city, Humayun's Tomb offers a quieter, more contemplative encounter with Mughal craftsmanship, and it's widely considered the architectural forerunner to the Taj Mahal.
The food alone justifies the flight. Delhi's street food culture is legendary — from parathas in the old city to chaat that will recalibrate your understanding of flavour. The city's restaurant scene spans everything from humble dhabas to refined North Indian cuisine, and eating adventurously here is one of life's genuine pleasures.
Timing matters enormously. October through January is the sweet spot: cooler temperatures, clear skies, and the festive energy of the holiday season make this the most enjoyable window to visit. Summer, by contrast, brings intense heat, and the monsoon season, while atmospheric, can complicate outdoor sightseeing.
From Indira Gandhi International Airport, the Delhi Metro's Airport Express Line connects directly to the city centre quickly and affordably — it's one of the most efficient airport rail links in South Asia and will save you both money and the stress of navigating traffic. Speaking of which, Delhi's roads can be genuinely chaotic, so building extra time into any ground transfer is always wise.
One tip that pays dividends: if your budget allows, position yourself in the New Delhi or Lutyens' Delhi area. You'll be within reach of both the historical old city and the more spacious, leafy southern neighbourhoods, giving you the best of everything this extraordinary capital has to offer.
