Cheap flights how to find: start with flexibility
Most people searching for cheap flights and how to find them begin with a fixed destination and fixed dates, then hope the price cooperates. That order is the main obstacle. The cheapest options usually appear when at least one variable is loose: the destination, the travel dates, or the trip length. The more you can relax, the more of the market you can see.
Before opening any search tool, decide which of those three you can actually bend. A traveller with a fixed wedding date but no fixed return day has a different search from someone who simply wants a sunny week sometime in spring. Writing this down first stops you from abandoning flexibility the moment a convenient but expensive result appears.
This also answers the limits part of the question. A low fare is only useful if it fits a trip you can really take, at a total cost that still makes sense, under travel rules that apply to you. Everything below follows from that.
Use map-style search to see options, not to decide
Broad search tools are built for the flexible stage. Google's help page on finding plane tickets with Google Flights describes searching for flights and finding destinations from where you are departing. Used this way, a tool helps you see where your departure city connects well before you commit to a single route.
Treat what you see as a starting map rather than a verdict. Features, filters and displayed prices in any third-party tool can change, so check the current help page instead of relying on a remembered workflow. The value lies in widening your list of candidate destinations, not in locking in a number.
Once you have three to five realistic candidates, narrow down. Look at the specific dates that work for you, compare direct and connecting routes, and note departure times. A fare that requires an overnight connection or a very early airport arrival may cost you more in sleep, transfers or a hotel than it saves.
What a deal label actually tells you
Deal sites and alerts are useful because they do the watching for you, but every deal label depends on a comparison point. When a site says a fare is cheap, the sensible question is: cheap compared with what? Without a stated reference, a deal label is just marketing.
Flare is one example of a service that states its comparison. It builds flight-deal discovery pages around a traveller's departure city, and its methodology page explains that it only surfaces a fare when it sits at least 30% under the reference price its monitoring uses for that route. That gives you a defined meaning for the word deal, but it is still a price observed at a point in time, not a promise that the fare will be bookable when you click through.
So use any deal source, Flare included, as a signal to investigate. The fare you can actually buy is the one confirmed by the airline or booking provider at checkout.
Price the whole trip, not just the seat
A cheap ticket can produce an expensive trip. Google's help page on finding plane tickets notes that the displayed price covers air transport including VAT/GST and airport taxes, but that additional fees, such as luggage or credit card fees, may apply. Seat selection, airport transfers, accommodation in a pricier destination and the cost of reaching a secondary airport can also erase the saving.
Build a simple comparison for each candidate rather than looking at headline fares alone. Include what you will genuinely need, not what the cheapest fare class assumes you need.
Costs to add before comparing:
- Checked or cabin bag fees for your actual luggage
- Payment or card fees at checkout
- Seat selection if you are travelling with others
- Transport to and from both airports, including late-night options
- Extra accommodation nights caused by flight timings
- Any visa or document fees that apply to you
- Change or cancellation terms if your plans are uncertain
Worked example: comparing two fares (hypothetical)
Example only, with invented figures for illustration. Sam has a free week in March and is choosing between two destinations. Destination A shows a headline fare of 90 and Destination B shows 140. At first glance A looks like the obvious choice.
Sam adds the full trip. Destination A's fare excludes a checked bag (adding 50), lands at a secondary airport with a long transfer (adding 30), and arrives after midnight, requiring an extra hotel night (adding 70). The total comes to 240. Destination B's fare includes a bag, lands at a central airport with a cheap train link (adding 10), and arrives mid-afternoon. Its total is 150. The apparently cheaper fare is the more expensive trip.
Sam then checks entry requirements for each destination based on Sam's own passport, confirms both fares directly with the booking provider, and books only after the price at checkout matches expectations. The lesson is not that B always wins, but that headline fares cannot be compared until the rest of the trip is added.
Final checks before you pay
Fares and seat availability move, sometimes within minutes. A price you saw on a discovery page, an alert or a comparison tool needs to be confirmed on the booking provider's own checkout before you treat it as real. If the price has changed, rerun your total-trip comparison rather than assuming the deal still holds.
Entry rules are personal. Passport validity, visa needs and health requirements vary with your nationality and your destination, and they can change. Check current official government sources before booking and again before departure.
Short pre-booking checklist:
- Fare and availability confirmed on the booking provider's checkout
- Total-trip cost compared across at least two options
- Baggage and change terms read for the exact fare class
- Passport validity, visa and health rules checked on official sources
- Arrival and departure times workable without hidden extra costs

Frequently asked questions
What is the most effective way to find cheap flights?
Stay flexible on at least one of destination, dates or trip length, use broad search or deal-discovery tools to build a shortlist, then compare the total trip cost including bags, transfers and accommodation. Always confirm the final fare with the booking provider before paying, because displayed prices can change.
Does a flight deal alert guarantee I can book that price?
No. A deal alert reflects a fare observed at a particular moment, and prices and availability can change before you book. Treat an alert as a prompt to check the fare directly with the airline or booking provider, and only rely on the price shown at checkout.
What should I check besides the fare before booking a cheap flight?
Check baggage and payment fees, change rules, airport transfer costs, arrival times that might require extra accommodation, and your own entry requirements. Passport, visa and health rules depend on your nationality and destination, so verify them on current official sources before booking and again before you travel.
