Booking Strategy
For Singapore to Delhi flights, book 6-8 weeks in advance for optimal pricing — this is when airlines release their lowest economy classes. Tuesday and Wednesday departures are typically €30-50 cheaper than Friday-Sunday. The monsoon season (June-September) offers the lowest fares, with July being the cheapest month at around €270-300 for economy. Diwali (October-November) and Christmas (December) see prices spike 40-60% — book 10+ weeks ahead if traveling during these periods. Use Google Flights for price tracking on this route, as it shows SIN-DEL pricing well. Mix-and-destination searches often reveal cheaper options via Bangkok or Kuala Lumpur, though total journey time increases significantly. Air India and IndiGo offer the best direct value; consider them first unless connecting flights have significant price differences.
Route Tips
- Changi Airport offers excellent Singapore-to-Delhi connections — use the free city tour if you have a 5.5+ hour layover between 6am-11:30pm
- Indian e-visa takes 3-5 days to process — apply well before departure as visa on arrival is not available for Singapore passport holders
- Delhi’s air quality can be poor November-February — those with respiratory issues should carry masks and consider booking morning flights when smog is thinner
- Terminal 3 at DEL has excellent food options including Indian chains — eat before leaving airport if heading to budget hotels without restaurants
- Book Air India or IndiGo directly on their websites — they often match better prices than OTAs and have more flexible date changes
- If flying via Dubai or Doha, check visa requirements for transit country — many nationalities need a transit visa even for short layovers
- Delhi airport chaos is real — allow 3 hours minimum for international departures and use online check-in to skip queues
