Frequently asked

Which credit card points are best for flying to India?▼

Capital One miles and Citi ThankYou points transfer to Turkish Miles&Smiles at 1:1, which costs just 34,000 miles one-way in economy — the lowest of any program. Chase Ultimate Rewards and Amex Membership Rewards transfer to Aeroplan, which is best for business class with no fuel surcharges.

When is the cheapest time to fly from Washington DC to Chennai?▼

January–February is consistently the cheapest period of the year. The September 1–October 10 window is the best pre-Diwali sweet spot. Avoid October 15–November 10 (Diwali), December 20–January 5 (Christmas/New Year), and May 20–June 10 (summer school break) — fares spike 2–3× during these windows.

How far in advance should I book?▼

For economy during off-peak season, 6–8 weeks ahead is usually sufficient. For Diwali or Christmas travel, book 5–6 months in advance. Award seats for peak season can disappear 10–11 months out — set a fare alert and act early.

Does the Pakistan airspace closure affect my flight?▼

Yes, if you're flying Air India. Their North America–India routes are currently 3–6 hours longer and may include a refueling stop in Vienna or Copenhagen. Other airlines (Emirates, Qatar, Turkish, Etihad) are largely unaffected as they route via Gulf hubs anyway.
