Travel experts reveal how to find cheaper holiday flights

For years, travelers have chased a supposed formula for finding cheap flights: browse in incognito mode, delete your cookies and book on a Tuesday.

These days, that advice is about as current as printing directions before setting off on a road trip.

Airfares now shift constantly in response to real-time demand and search data. As a result, no single day of the week is guaranteed to deliver the lowest price.

The more reliable strategy is to stay flexible about travel dates, track fares regularly and learn when prices are typically at their lowest.

New Google Flights data for 2026 shows that domestic tickets have recently reached their lowest prices about 39 days before departure, while international travel generally favors booking further in advance.

Travel specialists Cory Miller and Erika Kullberg told the Daily Mail that passengers should avoid both panic-buying and holding out until the final moment for an unlikely bargain.

Because the price of the same flight can swing by hundreds of dollars, patience and regular monitoring may save far more than repeatedly refreshing a booking site on Tuesday morning.

Here are the flight-booking strategies that may leave travelers with more money to spend once they reach their destination.

Forget the Tuesday booking myth

There is no reason to set an alarm for Tuesday and rush to search for airfare.

Cory Miller, founder of The Flight Expert, says the long-standing belief that airlines release their cheapest tickets on a specific day no longer reflects how fares are priced.

‘Buying on Tuesdays is an outdated idea. Algorithms adjust prices 24/7, making the purchase day irrelevant,’ he says. The more important consideration, he adds, is the day you actually travel.

Miller says flying during the middle of the week can often cost less because demand is lower, creating potential savings over weekend departures.

Erika Kullberg, a lawyer and personal finance expert, also says the travel date usually matters much more than the day a ticket is purchased.

‘Fares are driven by demand, and typically mid-week flights have lower demand,’ she says. ‘So, if you have flexibility on dates, it’s better to fly on a Tuesday or Wednesday.’

Recent research supports that approach. Expedia’s 2026 Air Hacks report identified Tuesday as the least expensive day for domestic flights, with average fares 14 percent lower than Sunday departures.

Google’s latest 2026 analysis likewise found that shifting the dates of a trip can make a substantially greater difference than changing the day on which the ticket is booked.

Put simply, the key question is not whether you buy on Monday, Tuesday or Wednesday. It is whether you can travel on a less busy day.

Start watching well before you’re ready to buy

One of the most common booking mistakes is believing travelers must choose between buying extremely early and waiting until the last possible minute.

The better approach is to start monitoring prices well before the trip. Miller recommends watching domestic flights around three to six months ahead and aiming to buy roughly one to three months before departure.

For international trips, he suggests starting the process six to 12 months out and aiming to book at least three months before takeoff.

‘The one window to avoid is the final 30 to 45 days before departure, when fares usually climb,’ Miller said.

There is an important caveat: There is no universal booking window that works for every route.

Google’s latest flight data found that US domestic fares have recently been cheapest around 39 days before departure, with a broader low-price range of roughly 22 to 57 days.

For international flights, Google found the lowest prices around 89 days before departure, although the low-price range stretched from roughly 50 days onward.

That means travelers should use these numbers as a guide rather than a countdown clock.

Peak periods are another matter. For Christmas, Thanksgiving, spring break and major school holidays, experts recommend being more cautious about leaving things until the last minute because demand can overwhelm the cheaper seats.

Let the price come to you

Rather than checking the same flight every morning and watching the price creep up and down, set an alert and let technology do the stalking for you.

Google Flights has a free ‘track prices’ feature that can send notifications when fares change significantly. Travelers can monitor particular dates or select ‘Any dates’ if they have flexibility. Kullberg says this can make a dramatic difference.

‘I tracked one round trip from Tokyo to New York where the price ranged from $1,643 at its peak to $914 at its lowest,’ she says.

‘That’s a $729 difference for the exact same trip, just from booking at the right moment.’ That is why it can pay to start looking before you actually need to buy.

Google Flights can also warn users when its system predicts that prices are likely to rise, although its forecasts are not guarantees.

The trick is not to wait forever for the mythical rock-bottom fare. If a price already looks unusually good, there is always a risk that waiting for something even cheaper will end with a much more expensive ticket.

Don’t bother with incognito mode

If you have ever frantically opened a private browser window after seeing a fare jump by $100, you are not alone.

But there is little reason to believe that airlines are punishing you for repeatedly searching for the same flight. Miller says airlines do not use cookies or an individual’s search history to raise fares.

‘Fares increase simply because real-time demand fills the cheapest seat buckets,’ he says.

That means a price can genuinely rise while you are searching – but that does not necessarily mean the airline has spotted you personally and decided to charge you more.

As cheaper fare buckets sell out, the next available price can simply be higher. So go ahead and use incognito mode if it makes you feel better, but don’t expect it to magically unlock a cheaper ticket.

Be flexible – even by a day

Flexibility is one of the most powerful weapons in the bargain hunter’s arsenal.

If your schedule allows it, check the days immediately before and after your planned departure rather than searching only one fixed date.

Google Flights’ calendar and price-graph tools make it easy to see how fares change across different days.

Kullberg recommends using the calendar view to spot cheaper dates and the ‘Explore’ map to see where you could fly for less.

This can also mean considering a different airport.

A flight from a nearby airport may be considerably cheaper than the most convenient option, although travelers should factor in the cost and time of getting there before declaring victory.

And don’t automatically assume a nonstop is the cheapest choice. Google’s latest data found that nonstop tickets can cost around 20 percent more on average than itineraries with a connection.

For a short flight, the extra connection may not be worth the hassle. But on a long-haul trip, it could potentially make a substantial dent in the fare.

If the price drops after you book, don’t panic

Finding out that your flight has dropped in price the day after booking can feel like a personal insult.

But depending on the airline and fare type, you may not necessarily be stuck with the original price.

Miller recommends setting price alerts even after booking, particularly when the ticket allows changes without a fee.

‘If you book Main Cabin on a major U.S. carrier, there are no change fees,’ he says. ‘If the price drops later, you can rebook and get the difference as travel credit.’

The important words here are ‘fare type’ and ‘airline.’

Basic economy tickets often have more restrictions, while policies vary between carriers, so travelers should check the exact conditions attached to their ticket before assuming they can rebook.

If a cheaper fare appears, compare the new ticket price with any cancellation restrictions or fare differences before making a change.

Have a last-minute backup plan

Sometimes life gets in the way and you have no choice but to book late.

That is when Kullberg suggests looking beyond cash fares.

‘Cash fares usually jump close to departure, but award prices often stay flat,’ she says.

‘Last minute is when points and miles give you the most value.’

For travelers with a stash of airline miles or credit-card points, award availability can therefore be worth checking before handing over a large cash payment.

Kullberg recommends Seats.aero as one tool for searching award availability across multiple airline and loyalty programs.

The site allows users to search for flights bookable with points and miles and set alerts for award availability.

But award seats can disappear quickly, and mileage prices can also change, so travelers should always confirm the final availability and terms with the airline or loyalty program before booking.
