Open multi-airline search for round-trip fares from SFO to KTM with outbound date flexible across October 2026 and return flexible across November 2026. Use 1 adult, economy, include 1–2 stops, and allow 24–30 hour total duration as filter.
Open the lowest results on the carriers' own sites (e.g., Qatar Airways, Turkish Airlines, Singapore Airlines, Cathay Pacific, Air India, ANA) to confirm price and change/cancellation rules.
Choose the specific October outbound date that meta-search calendar marks as lowest fare (often weekday mid to late October). Cheaper fares commonly appear Tuesdays–Thursdays; confirm exact date and routing (likely 1–2 stops via Middle Eastern or Asian hub).
If the carrier's site matches the meta-search lowest fare and provides standard protections, book directly; otherwise use a reputable OTA (e.g., Skyscanner partner or Kiwi) if significantly cheaper. Save fare conditions and PNR.
Pick the November return date marked lowest in the meta-search (typically weekday in early–mid November). Verify connection times and total travel time; avoid overnight long layovers if possible.
Complete booking for the round-trip itinerary if outbound and inbound combined price remains lowest; otherwise finalize separate one-way tickets only if cheaper after checking baggage and transfer rules.
Ensure e-ticket numbers, PNRs, and total price match expected amount; screenshot confirmations and check baggage allowance and change/cancellation fees.
If not yet booked, set alerts for price drops across Google Flights and Skyscanner; consider waiting up to 2–3 days if alerts show potential lower fares but book if risk of sellout exists.
