Direct flights usually offer convenience and save travel time, but they are not always the most budget-friendly choice. Flights with layovers can sometimes be significantly cheaper, especially for longer routes. Consider your priorities for cost versus travel duration.

Can flexible travel dates help on Seattle to Kolkata flights?

Yes, having flexible travel dates can often lead to finding more affordable flights. Prices can vary significantly between different days of the week or even within the same month. Flying during off-peak seasons or weekdays may result in lower fares.
