Travelers have found it’s best to book a flight 31 days in advance to save up to 32% compared to booking the same week of travel. As your travel date approaches, the cost of this flight route may potentially increase. While opting to book 31 days out may not be an option for all, there are still additional ways to secure a deal in the near future. You might find a flight from Costa Rica to Delhi 1-2 weeks in advance for as low as $1,127, or $1,352 for flights within the next 24 hours.
Due to multiple factors, expect to potentially pay more when booking in December. For low rates, February can be a great choice for travel to Delhi. Flights to Delhi from Costa Rica in February are about $997 on average during February, but can be found for as low as $625.
