Which connection works best from Houston?
Dubai (fastest about 25h 10m), Doha (fastest about 20h 50m) came up most often in our latest search. Gulf hubs usually give the shortest total time; European hubs can work better on price, baggage or schedule. We also check the layover length, terminal changes and transit visa rules for your passport before you book.
When should you book?
November to February is the pleasant season in Kolkata. The monsoon runs from June to September. Fares from Houston rise fastest around Durga Puja in September–October, Diwali and the December holidays, so book those dates early. Shoulder months usually price better if your dates are flexible.
