Real fares, not estimates
Every price on this page came from an actual airline search, never a formula guessing what a fare "should" be.
The Seat Itself
"Business class" is sold as one thing. It isn't.
A single airline can fly a true flat bed on one aircraft and a seat that reclines to 160°, sliding you down it all night, on another, both branded identically, both the same price.
We read the actual aircraft on your route, not the name on the fare, so the seat you're promised is the seat you get.
EgyptAir alone flies all three: a flat bed on the 787-9, a 160° angled seat on the 777-300, and a recliner on the A320neo.

Fine for a film. Not built for a night
The Body Clock
We buy the flat bed exactly when it earns its keep.
A lie-flat seat at 01:00 is worth ten times the same seat at 10:00, so so instead of pricing the whole trip in one cabin, we price every sector against your body clock, and only spend up where it actually buys you sleep.
Same aircraft, same seat, same money. The outbound buys you nothing. The flight home buys you six and a half hours.
After two weeks in Bangkok you're adjusted to local time, so the return is scored on that clock, not London's. We track the drift so you don't have to.

Flat bed, squarely inside your night. This is the seat worth buying.
The Cabin Ladder
The upgrade worth buying isn't always the small one.
Every other site shows you three prices and leaves the arithmetic to you. We price the step, and the answer often runs against the usual advice.
On this trip, premium economy costs £201 for every extra hour of sleep. Business costs £84. The bigger step is the better buy, and you'd never see that from the headline fares alone.

Every verdict scales to what an hour of sleep is worth to you. Raise that number and premium economy still won't clear the bar.
The Split Ticket
Start in the right city. Same seat, hundreds less.
Airlines file fares by market, so the same business seat costs different money depending on which city your journey starts in. Bangkok via Cairo came in £469 under flying straight from London. Copenhagen to Singapore ran £637 under. Same dates, same cabin, same flat bed.
We check every origin worth checking and show you only the ones that come out ahead once the extra flight, the layover and the hotel are paid for. The rest never reach your screen. That is the difference between a saving and a number that looks like one.
A missed connection here would cost £1,892 in a worst case. At nearly fifteen hours of slack, that's roughly a 2% chance. We'd rather you knew the number than not.

The Evidence
Every price here came from a live search.
29,321 real fares, read down to the seat filed on each aircraft. Nothing here is modelled, averaged, or a formula guessing what a fare ought to be.
The gaps are big and they are specific. Cairo runs 41% under London in business. Vienna beats every city we tried to Sydney. Those margins move daily, so we re-price yours on every search rather than trusting last week's answer.

How the maths actually works
Risk, priced in pounds
Split tickets carry real connection risk. We calculate the odds and the cost of a miss, and show you both before you book.
We say when it's not worth it
Most routes simply aren't cheaper elsewhere, and we say so. That's exactly why you can trust it when we say one is.
You pay the airline, not us
No booking fees, no markup, no card details on our site. We find the trip; you book it direct, at the airline's own price.
