You can consistently find cheap flights by combining flexible search tools, smart timing, and a few lesser-known booking tricks.

Quick Scoop

  • Use flight search engines (Google Flights, Skyscanner, Momondo, Kayak) as your starting point, not airline sites.
  • Be flexible with dates, airports, and even destinations to unlock big price drops.
  • Track deals and “error fares” via specialist deal sites and alerts instead of manually hunting every day.

Best Places to Look (Core Tools)

These are the main “hubs” where people reliably dig up cheap fares today.

  • Google Flights – Fast, clean calendar view to see the cheapest days in a month; great for flexible dates and trying multiple destinations quickly.
  • Skyscanner – Excellent for “Anywhere” searches and full‑month price views; handy for spotting unusually low fares and even potential error fares.
  • Momondo – Strong at comparing many airlines and agencies; its “Flight Insight” shows cheapest day to fly, best time to book, and cheapest airports on a route.
  • Kayak – Powerful meta‑search across many sites, plus flexible date search and price alerts.
  • FlightList & similar “explore” tools – Let you plug in a date range and see where you can go cheaply from your home airport.

Think of these as your radar : they don’t sell the ticket; they help you see who’s selling it cheapest.

Deal & Error-Fare Hunters

These services watch for unusually low prices and “mistake fares,” then push them to you.

  • Thrifty Traveler (and similar premium/free deal newsletters) – Curated lists of under‑the‑radar flight deals, especially international and long‑haul.
  • Going (formerly Scott’s Cheap Flights) & others – Focus on sale and error fares from your chosen departure airports.
  • Airfarewatchdog, Secret Flying, Kiwi.com deals pages – Aggregate sales and error fares in one place, sometimes with routes you might not think of yourself.

These are best if you’re flexible on where and when you travel and just want “something cheap and exciting.”

Comparison & Strategy Tips From Forums

Travel and frugal forums repeatedly share similar strategies that still work in 2025–2026.

  • Fly mid‑week if possible (Tuesdays and Wednesdays often price lower than weekends).
  • Be flexible by Âą1–3 days; tiny shifts in departure/return can knock a big chunk off the price.
  • Don’t automatically insist on direct flights; adding a layover can cut prices 20–40% on some routes.
  • Avoid peak seasons (major holidays, school breaks, big events) when routes spike in price.
  • Check both:
    • Online travel agencies (OTAs) via comparison sites.
    • Direct airline websites to see if they match or undercut the OTA fare.

Forum users also stress setting up price alerts on these platforms so you get notified when a fare drops instead of constantly re‑searching.

Advanced / Hacky Options (Use With Care)

Some tools use more aggressive routing or booking logic; they can save money but come with caveats.

  • Skiplagged (hidden‑city ticketing) – Shows itineraries where you get off at the layover city because it’s cheaper than a direct ticket there; can save a lot but:
* No checked bags, risk of airline disapproval, and not good for round‑trips on one ticket.
  • “Build‑your‑own” connections – Using sites like Kiwi.com or manually booking two separate tickets to create cheaper connections, especially for long‑haul.
  • Splitting journeys – Booking separate legs (e.g., your city → hub, hub → final destination) can sometimes save ÂŁ100s on long routes.

These are best if you’re experienced, have buffer time between flights, and are comfortable with a bit more risk.

Concrete Mini‑Plan: How to Hunt a Cheap Flight

Here’s a simple step‑by‑step you can reuse.

  1. Open 2–3 comparison tools
    • Start with Google Flights + Skyscanner + Momondo or Kayak.
  1. Search broadly
    • Set your departure airport (or region) and search “Anywhere” / multiple destinations, plus “flexible dates” or a full month view.
  1. Identify cheap days
    • Use the calendar/graph views to find the lowest outbound/return dates within your window.
  1. Compare booking options
    • For the best itinerary, check:
      • Direct airline site
      • One or two big OTAs shown in the comparison results.
  1. Set alerts if you’re not ready to book
    • Turn on price alerts on Google Flights / Skyscanner / Kayak, then wait for a drop rather than booking impulsively.
  1. Check deal newsletters
    • Quickly skim Thrifty Traveler, Going, or similar for surprise sales or error fares that match your general region and dates.
