Step-by-Step Guide to Finding Cheap SFO Flights

Here’s how to uncover the best SFO flight deals in 2025:

1. Use Flexible Dates

   • Flying midweek (Tuesday or Wednesday) can save you 30% or more. For example, a Honolulu flight drops from $400 to $280 RT in October. Use Google Flights’ flexible date search to compare prices across a month.

   • Tip: Avoid peak holiday seasons like December for the cheapest rates.

2. Book 2–3 Months in Advance

   • Planning ahead is key. Booking international flights like Tokyo ($707 RT) 2–3 months out or domestic flights like Las Vegas ($84 RT) 1–2 months ahead locks in lower fares. Our newsletter highlights these sweet spots.

   • External Link: Check Skyscanner for price trends.

3. Leverage Google Flights

   • Set up price alerts for your favorite routes (e.g., SFO to Paris or Bangkok). When prices drop below standard rates (e.g., $500 for Paris), you’ll get notified. We manually curate these alerts into our Google Sheets for the best deals.

4. Consider Budget Carriers

   • Airlines like Frontier (SFO to Las Vegas) or ZIPAIR (SFO to Tokyo) offer low base fares. Watch for baggage fees, but these can still deliver cheap SFO tickets under $300.

   • Tip: Book directly on their sites for the best rates.
