The cheapest day to fly is often midweek, especially Tuesday or Wednesday, when fewer people are travelling. But prices change constantly, so instead of relying on one “cheap day,” it’s better to compare flexible dates and look at the full cost of your flight.
“Flights are cheaper on Tuesdays.”
That’s the advice everyone gives.
So you:
- open Skyscanner on a Tuesday
- try to book midweek
- maybe even delay your trip hoping prices drop
And sometimes… it works.
But most of the time?
It doesn’t.
We’ve booked flights on every day of the week—
Monday mornings, Sunday nights, random midweek searches—and the cheapest flights never followed a neat pattern.
Because the truth is:
There isn’t one “cheapest day” to fly anymore.
But there is a smarter way to consistently find cheaper flights—especially as a family.
Quick Tip: Stop Guessing the Cheapest Day
There isn’t one “perfect” day to book flights.
The real advantage comes from using tools that show you:
- flexible dates
- cheapest combinations
- full pricing (including hidden costs)
👉 We compared Aviasales vs Skyscanner to see which actually works best:
Why the “Cheapest Day to Fly” Advice Is Outdated
This idea didn’t come out of nowhere.
Years ago, airlines used to:
- release deals at specific times
- update fares in batches
- follow predictable pricing cycles
So yes,”midweek (especially Tuesday) often was cheaper.
But today?
Airlines use:
- real-time pricing algorithms
- demand tracking
- competitor monitoring
Prices now change:
- constantly
- automatically
- based on demand, not the day of the week
Which means:
👉 There is no universal “cheap day” anymore
👉 The same flight can change price multiple times in one day
So if you’re still trying to “time” the perfect day…
You’re playing a game that no longer works.
What Actually Affects Flight Prices (This Is What Matters)
Instead of chasing myths, focus on what actually moves prices:
- Demand (biggest factor)
- Seasonality
- Route popularity
- School holidays
- Time before departure
This is why:
- a Tuesday flight in peak summer can be expensive
- a Saturday flight in low season can be cheap
It’s not about the day.
It’s about the context around the flight.
1. Midweek Flights Are Often Cheaper (But Don’t Rely on It)
Let’s clear this up properly.
Yes, midweek flights tend to be cheaper:
- Tuesday
- Wednesday
- sometimes Saturday
Because:
- business travel drops off
- leisure demand is lower
- fewer people are searching those days
But here’s the catch:
“Often cheaper” is not the same as “always cheaper.”
For families, this gets even trickier because:
- you’re often tied to school schedules
- flexibility is limited
- peak dates override everything
So use this as a guideline, not a rule.
2. The Biggest Lever: Flexible Dates
If there’s one thing that consistently works…
It’s this.
Even shifting your flight by:
- 1 day
- 2 days
can reduce costs significantly.
We’ve seen:
- £100–£300 differences per ticket
- just by moving departure slightly
Now multiply that by a family of four…
That’s where this really matters.
Most people search like this:
👉 exact dates
👉 fixed plans
But the real advantage comes from:
👉 comparing nearby days
This is where tools make a huge difference.
3. Time of Day Impacts Price More Than People Realise
This one gets overlooked constantly.
Flights at:
- 6am
- late evening
- red-eye times
are often cheaper than mid-day flights.
Why?
Because they’re less convenient.
Families usually default to:
👉 “easy flight times”
But sometimes:
- slightly inconvenient = significantly cheaper
It’s a trade-off.
And depending on your kids’ ages, it can actually work in your favour (early flights = less airport chaos).
4. Booking Timing Matters More Than Flight Day
Here’s the part most people get wrong.
They obsess over:
👉 what day to fly
But ignore:
👉 when to book
General pattern:
- too early → prices high
- too late → prices spike
- middle window → best value
For most trips:
- short haul → 4–8 weeks out
- long haul → 2–6 months out
But again, this isn’t fixed.
Which is why:
Tools beat timing every time.
5. The Real Advantage: Seeing the Whole Month
If you’re searching one date at a time…
You’re missing the bigger picture.
The cheapest flights aren’t found by guessing.
They’re found by:
- scanning ranges
- comparing patterns
- spotting dips
This is exactly why we use tools like:
- Skyscanner
- Aviasales
They let you:
- view an entire month
- instantly spot cheaper days
- avoid blind guessing

Because once you see prices visually…
Everything clicks.
6. Routes Matter More Than Days
This is where bigger savings often come from.
Instead of asking:
👉 “What day is cheapest?”
Ask:
👉 “Is this the best route?”
Sometimes:
- flying from a nearby airport
- adding a short layover
- splitting flights
can massively reduce cost.
Example:
- Direct flight = expensive
- Slight detour = much cheaper
Families tend to prioritise convenience (understandably)
But even small adjustments can:
👉 save hundreds overall
7. School Holidays Change the Game Completely
This is the reality most “cheap flight” advice ignores.
If you have kids:
You’re not playing the same game.
School holidays mean:
- peak demand
- limited availability
- higher baseline prices
So instead of chasing:
👉 “the cheapest day”
Focus on:
- booking earlier
- staying flexible within your window
- comparing properly
Because during peak periods…
The goal isn’t “cheapest possible”
It’s:
👉 avoiding overpaying unnecessarily
Family Reality: What Actually Works for Us
After doing this repeatedly, here’s what we’ve learned.
We don’t:
- wait for a specific day
- try to time the market
- chase “hacks”
We do:
- search flexibly
- compare across tools
- adjust slightly where possible
That’s it.
No tricks.
Just better visibility and decisions.
A Quick Example (Real Scenario)
We recently looked at flights where:
- Monday → expensive
- Tuesday → slightly cheaper
- Wednesday → significantly cheaper
But…
Another route showed:
- Friday → cheapest option
Same week. Different pattern.
That’s why fixed rules don’t work anymore.
The System We Actually Use
Simple and repeatable:
- Search flexible dates
- Compare across tools
- Adjust departure slightly
- Check nearby airports
- Book when price feels reasonable
No stress. No guesswork.

Final Thought
There’s no perfect day to fly anymore.
But there is a better way to book.
And once you stop chasing outdated advice…
Flights stop feeling random—and start making sense.
