How to tell a genuine price drop from a fake 'sale' price

The travel industry invented fake sales long before ecommerce did. A flight marked down from £450 to £280 looks like a win until you realise nobody ever paid £450 for that route anyway. Learning to spot the difference between a genuine price drop and inflated marketing takes five minutes — and could save you real money.

The anchor price trap

Travel sites love showing you a crossed-out 'was' price next to a 'now' price. The problem: that 'was' price is often fictional. Airlines and hotel chains set artificially high reference prices knowing they'll discount them, then use the discount to create urgency.

Flight prices especially are vulnerable to this. A budget airline might list a route at £200+ for a few days, then 'drop' it to £120 — but the actual market price for that route has hovered around £110–130 for weeks. You're not getting a deal. You're seeing marketing theatre.

What actually matters: historical range

A genuine price drop is when a flight or package falls below its normal range for that route and season. This is harder to spot because it requires knowing what that normal range is.

For popular European routes from Stansted or Luton — Barcelona, Madrid, Lisbon, Rome — you can build an intuition by checking prices across a few weeks. Real deals sit noticeably below what you've been seeing regularly.

The trick: browse the same route in different windows (incognito mode helps avoid price discrimination). If you see significant variation day to day, that's normal volatility. If you see one or two unusually cheap dates surrounded by higher prices, that might be a real drop worth acting on. If everything suddenly has a red 'sale' tag, that's usually marketing.

When fake sales actually happen

Airlines and hotels use inflated reference prices most aggressively during these periods:

• Bank holidays and school breaks: Demand spikes, so they set higher starting prices, then discount them. The 'discounted' price is often still above normal rates.
• Flash sales: A 48-hour 'deal' that's really just the price that will be available again next week. The urgency is manufactured.
• Round-number promotions: 'Save £50 on packages over £500' is often just a percentage off that they're framing differently than usual.
• Last-minute offers: Genuinely cheap, but because seats are actually hard to shift — not because of a sale mentality.

Real price drops and why they happen

Legitimate price reductions do occur. Knowing why helps you spot them:

Route competition: A new low-cost airline launches on a corridor, and existing carriers drop fares to stay competitive. This is real and worth acting on.

Off-peak timing: A flight in late September is cheaper than one in mid-September because summer holidays are over and autumn breaks haven't started. That's a genuine drop relative to peak demand, not a sale.

Oversupply: Airlines overestimated demand for a season, now they're dropping prices weeks ahead to fill seats. This is real — and happens more often than you'd think.

Fuel prices or currency swings: Occasionally, external factors push fares down across multiple operators. You'll see it industry-wide, not on one website.

Your practical checklist

When you see a 'deal', ask yourself:

• Does the crossed-out price look unusually high compared to what I've seen this route before?
• Is this price lower than my mental baseline for this route, season, and distance from travel date?
• Are other websites (not just one) showing similar pricing?
• Is there a real reason the price dropped (new competition, actual off-peak timing, good advance booking window)?
• Or is it just a red banner saying 'Sale'?

If a deal passes three of those five checks, it's probably real.

Use price tracking, not blind browsing

The easiest way to build intuition: set up alerts on routes you're interested in. Tools like Plof Air let you browse package deals from London airports and track prices over time. After a few weeks of notifications, you'll know what normal looks like for Dublin, Porto, or Berlin in your season.

That baseline is your superpower. Once you have it, a genuine drop becomes obvious. You stop clicking on red banners and start clicking on prices that are actually below the line.

The travel industry will always try to create urgency. Your job is to ignore the theatre and look at the numbers in context. Real deals exist. They're just cheaper than the marketing wants you to think.
