How to compare flight prices properly: nearby airports, one-ways and the fees that hide
Flight prices move more than any other travel product, and the cheapest fare is rarely on the first site you check. A few habits consistently find lower totals.
Use metasearch first
A metasearch engine like KAYAK queries airlines and booking sites at once and lists them by price. That replaces a dozen tabs. It also shows the airline’s own fare next to the OTA fare, which is the comparison that matters most.
Check nearby airports
Many cities have a second airport with lower fares: Toronto Island versus Pearson, Gatwick or Stansted versus Heathrow, Burbank versus LAX, Fort Lauderdale versus Miami. Most search tools let you include nearby airports in one query.
Try two one-ways
Especially on low-cost carriers, two separate one-way tickets can be cheaper than a return, and give you the flexibility to fly different airlines each way.
Add the fees before deciding
Basic economy and low-cost fares exclude checked bags, seat selection, and sometimes carry-on. A $60 gap between fares can vanish once a bag is added on each. Compare the total for the way you actually travel.
Timing
Domestic fares are usually best 1–3 months out; long-haul 2–6 months out. Sunday and Tuesday departures are often cheaper than Friday. None of these are rules, which is exactly why comparing beats guessing.
