Find Discounted Flights: Compare Cheap Airline Tickets & Airfare Deals Before Prices Go Up
Discounted flights are real, but they are rarely found on a single website. The most reliable method to compare cheap airline tickets and airfare deals is to use a metasearch engine like Kayak, Skyscanner, or Google Flights to scan hundreds of airlines and OTAs at once, then book directly with the airline once you spot the lowest fare.
As of this year, historical data consistently shows that Tuesday and Wednesday departures yield the lowest average ticket prices for international routes, while booking at least three weeks ahead for domestic trips avoids last-minute surcharges.
I once spent three hours jumping between seven browser tabs trying to find a Lagos to London fare that did not make me wince. That was before I understood how airline pricing actually works. Chidi from our Abuja team now books all his WakaAbuja research trips using the specific workflow I will lay out below, and he has not overpaid since.
This is not a generic list of booking sites. This is the system we use internally, built on airfare data patterns that hold steady year after year.

Key takeaways
- No single booking site consistently has the lowest fare. Metasearch engines like Kayak and Skyscanner win by comparing across hundreds of sources.
- The cheapest day to fly internationally is Wednesday, and the cheapest month is January, based on multi-year aggregate booking data.
- Search in private browsing mode and clear cookies. Airlines and OTAs use dynamic pricing based on your search history.
- Budget airlines like Wizz Air and Ryanair do not appear on many metasearch engines. You must check them separately.
- Setting a price alert three months before your travel window is the single most reliable way to catch a discount.
Which flight search engine actually finds the cheapest tickets?
I have run the same flight searches across five engines on the same day, same route, and same time of day. The results diverge by up to 40 percent. Kayak consistently surfaces the broadest range of OTAs and has a useful “Hacker Fare” feature that combines two one-way tickets on different airlines into a round-trip priced below any single airline’s fare. Skyscanner excels for open-ended searches when you do not have fixed dates, thanks to its “Whole Month” calendar view. Google Flights is the fastest for a quick check and gives you a price graph that loads before you blink.
Momondo sometimes uncovers smaller OTAs that the bigger engines miss, though it takes longer to load results. Expedia packages can beat everyone if you bundle a flight with a hotel you already intended to book. The point is this: pick two engines and check both before you swipe your card. I use Kayak for my main search and Skyscanner for a backup scan. Chidi swears by Google Flights for quick Lagos-Abuja hops and switches to Kayak for international routes.
Chidi’s honest take: “I found a Lagos to Warsaw fare on Kayak that was 120 USD cheaper than the exact same flight on Expedia. Same airline, same flight numbers. The difference came from an obscure OTA that only Kayak indexed. That paid for my first three days in Poland.”
What is the actual cheapest day to book and cheapest day to fly?
Let me kill the myth first: Tuesday booking is not the magic bullet it was a decade ago. According to airfare data aggregators, the cheapest day to fly domestically is Tuesday or Wednesday, and the cheapest day to fly internationally is Wednesday. The cheapest month to fly, consistently across both domestic and international routes, is January. Shoulder months like May and September offer the next-best combination of decent weather and lower fares. I book most of my research trips in late September for this exact reason.
The savings are not trivial. Average international economy fares in January are roughly 20 to 25 percent lower than July peaks. The gap widens further for business class, where January discounts relative to June can hit 40 percent. Avoid flying on Fridays and Sundays if you want cheap tickets. These are the peak business and leisure days, and airlines price accordingly. A Wednesday-to-Wednesday international itinerary saves you money on both ends of the trip.
Best for domestic flights
- Fly Tuesday or Wednesday.
- Book 3 to 6 weeks ahead.
- January and February offer the lowest base fares.
- Set a price alert 2 months before your target window.
Best for international flights
- Fly Wednesday, departing mid-week.
- Book 2 to 4 months ahead for long hauls.
- January is the single cheapest month, followed by November.
- Use a VPN to check prices from different countries.
How to find cheap airline tickets using fare tricks airlines do not advertise
These are the methods I use when the published fares are stubbornly high. They require a little flexibility but have saved me serious money multiple times.
The skiplagging risk and when it works
Skiplagging, booking a flight with a layover and intentionally missing the second leg, is widely known now. Airlines explicitly ban it in their conditions of carriage. I do not recommend it for international travel because if you skip a leg, the airline cancels the rest of your itinerary. For domestic one-ways with no checked luggage and no return flight on the same booking, it still works. Weigh the savings against the risk of losing your frequent flyer account.
Error fares and flash sales
Error fares happen when an airline or OTA publishes a fare with a missing zero or a currency conversion glitch. They last hours, not days. The only way to catch them is to follow accounts that track them in real time. I use Secret Flying and Scott’s Cheap Flights alerts. When you see one, book immediately. Do not call the airline to confirm. Wait for the ticket to be issued, then check 48 hours later to see if it was honored.
VPN-based location pricing
Airlines price differently based on your point of sale. A Lagos to London ticket searched from a Nigerian IP address may show a different fare than the same route searched from a UK or Moroccan IP. Use a VPN set to a lower-income market or the airline’s home country. I saved 80 USD on a Turkish Airlines booking by searching from an Istanbul IP instead of my Nigerian connection. Always book in the local currency using a card with no foreign transaction fees, because the airline’s dynamic currency conversion rate is often terrible.
What are the most expensive mistakes people make when searching for airfare deals?
I have watched smart travelers light money on fire doing these things. Here is what to stop doing immediately.
- Searching the same route repeatedly without clearing cookies. OTAs and airline sites use cookies to track your searches. The fare magically goes up each time you check. Search in a private window or clear your browser cache between sessions.
- Ignoring budget airlines that do not list on metasearch. Wizz Air, Ryanair, and sometimes AirAsia do not appear on Kayak or Google Flights. You must check their direct websites. In Europe, a Wizz Air seat can cost 30 EUR for a route Kayak shows at 180 EUR on legacy carriers.
- Waiting for a last-minute deal that never comes. The last-minute fire sale is largely extinct. Airlines now use revenue management algorithms that raise prices sharply in the final two weeks because the remaining buyers are usually business travelers with inelastic demand.
- Booking a fare with a long layover to save 20 dollars. A 12-hour layover in Doha sounds bearable until you are on hour seven and have spent 40 dollars on airport food. Value your time at a realistic hourly rate.
- Not checking the total cost with luggage. A 50 USD base fare becomes a 110 USD fare once you add a carry-on, checked bag, and seat selection. Always click through to the final payment screen before comparing two fares.
- Using a debit card for international bookings. Credit cards offer Section 75 protection and chargeback rights that debit cards do not. If an OTA collapses, a credit card chargeback gets your money back. A debit card dispute is slower and far less certain.
Frequently asked questions
Do flight comparison sites show all available airlines?
No. Most metasearch engines exclude budget carriers like Southwest, Ryanair, and Wizz Air by default or due to commercial agreements. Always run a separate check on the budget airlines that operate on your intended route before concluding you have seen every fare.
Is it safe to book through an online travel agency instead of directly with the airline?
Reputable OTAs like Expedia and Priceline are generally safe, but the real risk is when something goes wrong. If your flight is canceled, the airline will refer you back to the OTA for rebooking. Some discount OTAs have nearly nonexistent customer service. Book with a credit card so you have chargeback protection regardless.
When is the best time to set a price alert for discounted flights?
Set it the moment you know your travel window, ideally three to four months before departure for international routes. Kayak and Google Flights both offer free price alerts. The alerts track fare changes and notify you when prices drop below the historical average for that route.
Are one-way tickets ever cheaper than round-trip fares?
For legacy international carriers, one-way tickets are often significantly more expensive than half a round-trip fare. Budget airlines price one-ways at true half-cost, so mixing two one-way budget tickets can undercut a legacy round-trip. Kayak’s Hacker Fare tool automates this comparison.
Why did the price go up the second time I searched the same flight?
This is dynamic pricing driven by cookies and cached browsing data. The airline’s system registers your repeated interest and adjusts the displayed price. Search in an incognito or private browsing window and clear your cookies between searches to see the baseline fare.
Do student or youth discounts still exist for flights?
Yes, but they are less common than they were. StudentUniverse and STA Travel offer verified student/youth fares, usually on full-service carriers. The discount is often a more flexible change/cancellation policy rather than a drastically lower base fare. Compare their price against a regular search before assuming the student fare is cheaper.
