Everyone has a theory about scoring a cheap flight. Most are folklore. Here is what actually stands up to the evidence — useful timing for a busy summer travel season out of Los Angeles.
When to book
Forget the magic "six weeks" rule. For domestic trips, fares tend to be lowest booked somewhere in the range of about three to seven weeks ahead; for international travel, further out — often two to five months, NerdWallet notes. What is consistent is the tail end: prices climb sharply in the final week or two before departure, so waiting for a last-minute steal usually backfires. Just as important is the season — late summer into fall is generally cheaper than the June-through-August peak.
When to fly
The day you fly matters more than the day you book. The old advice to "buy on Tuesday" barely moves the needle. But flying midweek — Tuesday and Wednesday, and increasingly Friday — is meaningfully cheaper than a Sunday return, one of the priciest days to travel. Early-morning and red-eye departures can also run lower because fewer people want them. Use a flexible-date search to see the actual cheapest days for your route.
The myths to drop
One tenacious myth: browsing in incognito mode or clearing cookies unlocks lower fares. It doesn't. In a test of hundreds of searches, Consumer Reports found the vast majority returned the same price regardless of browsing history, the group reported; airlines price on demand and seat inventory, not your search trail. Set price alerts on the routes you're watching, and let the tools — Google Flights, Kayak, Skyscanner, Hopper — do the checking for you. Comparing more than one search site helps, since no single one is always cheapest.
The airport question — worth checking, not a guarantee
Angelenos have five airports to weigh, and the fare math is more interesting than the clichés suggest. On average, Burbank (BUR) and Long Beach (LGB) fares run notably lower than LAX — roughly 20% below, according to federal fare data, tracked by the Bureau of Transportation Statistics — largely because budget carriers dominate there. Ontario (ONT) tends to land in between, while John Wayne/Orange County (SNA) often runs slightly above LAX.
But those are averages across each airport's mix of routes, not a promise on your specific trip: LAX's enormous carrier competition and vast route map can make it the cheapest option on many common flights, and it is the region's main gateway for international and long-haul travel. The takeaway isn't "always fly Burbank" — it's to price your exact route at a few airports, then weigh any savings against the drive, parking (far cheaper at the smaller fields) and time.
Watch the fees
A low headline fare can evaporate at checkout. Basic-economy tickets frequently exclude seat selection and even a carry-on bag, and airlines increasingly earn a large share of revenue from add-ons, so compare the full trip cost, not the teaser price. If you fly a lot, a free frequent-flyer account and a travel rewards card can build toward future trips. And "mistake fares" — genuine airline pricing errors — are real and legitimate to book; alert services surface them, but they vanish fast, so treat them as a lucky bonus rather than a plan.
The honest bottom line
There is no trick that guarantees the lowest price; airlines use dynamic pricing, and the same search can look different a day later. The reliable approach is to stack small advantages: be flexible on dates, price a few nearby airports for your route, set alerts, book a fair fare instead of chasing a perfect one, and read the fine print. For summer travel from LA, flexibility saves more than any single hack.
