How It Works

How HolFly monitors prices

We check live fares on your behalf, build a price history, and surface deals using statistical analysis — so you know whether today's price is a real bargain or just average.

1
Live price checks
At each scheduled check time we query live fares across all your origin airports to your destination, filtered by your cabin, stops, and trip-length preferences. Each result is stored with a timestamp.
2
Price history & trend detection
Prices are tracked over time. We compare your last 7 days against the 7 days before that. If the average moves more than 5%, you'll see a rising or falling trend indicator on your dashboard. Longer history windows (Traveller/Family) make this far more reliable.
3
Percentile deal scoring
Every deal is scored against the distribution of prices we've seen for that route. A price below the 25th percentile gets a Below average badge — meaning it's cheaper than 75% of all prices seen. Above the 75th percentile gets Above average. This beats a simple "up/down" signal because it tells you how good the deal is in absolute terms.
4
Seasonal peak detection
For popular routes (India, Gulf), we know historically when prices spike — Diwali, Christmas, summer school holidays. When your travel dates fall within 12 weeks of a known peak window, you'll see a banner prompting you to consider booking sooner.
Why price history length matters
Free — 7 days

You can see this week vs last week. Enough to spot a sudden spike, but you can't tell if today's price is seasonally high or genuinely cheap. A price of £380 might look normal when the week before was £390 — but zoom out and you'd see it's been £320 all month.

Traveller — 30 days

A full month of data powers the percentile badges — you can see where today's price sits in the distribution. You'll catch the mid-month dip that 7-day users miss entirely, and the trend indicator becomes statistically meaningful.

Family — 90 days

Three months of data reveals seasonal patterns — the Diwali spike in October, the January lull, the summer school-holiday surge. The AI prediction model is trained on this full window, giving you a reliable forecast of whether prices will rise or fall in the next 2–4 weeks.

Which plan is right for you?

Honest guidance — the Free plan is genuinely fine for many people.

✈️
Free Plan
The once-a-year traveller

You fly home once a year — say, Chennai (MAA) or Mumbai (BOM) — and you're happy to wait for a good deal rather than chasing every fare movement. You just want to know when the price drops noticeably.

Free is enough. One route, one check a day, 7-day trend. You'll get an email when prices move. At £0/year, the maths is obvious.
🧳
Traveller — £39/yr
The deal-conscious traveller

You fly 2–3 times a year, care about timing, and know that catching a flash sale on a Tuesday morning can save £150+. One missed deal pays for years of subscription.

  • 3 checks/day — flash sales last hours, not days
  • 30-day history — see if today's price is actually cheap
  • Percentile badges — know when to book with confidence
  • Price threshold alerts — only notified when it's worth it
  • Share deals — send a deal card to travel companions
Worth it if: saving £50+ on a single booking matters to you. At £3.25/month, it usually does.
👨‍👩‍👧‍👦
Family — £59/yr
The family or frequent flyer

Multiple people travel, or you manage trips across different routes — parents visiting from India, kids going back for holidays, work trips mixed in. You need a full seasonal picture.

  • 10 profiles — monitor MAA, BOM, DEL all at once
  • 6 checks/day — catches overnight and weekend fares
  • 90-day history — full seasonal price curve
  • AI price predictions — will prices rise or fall next month?
  • No watermark on shared deal cards
Worth it if: you're coordinating travel for more than one person, or you fly frequently enough that knowing the seasonal curve saves you £100+ a year.
Why check frequency matters more than you'd think
Real scenario: A London–Chennai fare drops to £298 at 11 PM on a Thursday night for 4 hours. A Free user's single daily check (runs at 6 AM) never sees it. A Traveller user's 3× daily checks catch it at the 11 PM slot.

Airlines release flash sales, mistake fares, and last-minute inventory at irregular hours. A single check per day has roughly a 1-in-24 chance of hitting the right window. Three checks per day raises that to roughly 1-in-8. Six checks (Family) means you almost never miss a fare that lasts more than 4 hours.
