Which Airlines Have Lie-Flat Business Class
108 of 120 scored business cabins go fully flat · 261 routes checked
Almost every long-haul business class sold today is advertised as lie-flat, and CabinScore finds that 90% of the 120 business cabins it has measured genuinely are. The useful question is the other one: where does an airline still fly a seat that doesn't go flat, and can it turn up on your booking?
What this page is not: a complete audit of any airline. CabinScore measures cabins on the 261 routes it tracks, and even there 49 aircraft types it has seen flying are not scored yet. So every line below is a statement about what CabinScore has measured, not about everything an airline flies. Where a cabin is missing a recline figure the page says so rather than guess.
Airlines Flying a Business Cabin That Doesn't Go Flat6 airlines
The one thing on this page that needs no qualification: CabinScore has measured at least one business cabin from each of these airlines that does not recline to a flat bed. That is a positive finding, so it holds however much of the rest of their fleet CabinScore has scored.
Flat on Everything We've Measured3 airlines
Every business cabin CabinScore has measured for these airlines goes fully flat, and CabinScore has scored every aircraft type it observes them flying on tracked routes. That is the strongest statement the data supports — it still says nothing about routes CabinScore doesn't track or aircraft it has never seen them operate.
Flat So Far, But We Haven't Seen Everything17 airlines
Every business cabin CabinScore has measured for these airlines is flat — but it has not scored every aircraft type it sees them fly, so this is not a guarantee. The count next to each airline is exactly how far the coverage goes.
The Cabins That Don't Go Flat11
Every business cabin we have measured as not reclining to a flat bed, worst first. If your flight is operated by one of these, the “lie-flat business class” on the booking page is not what you booked. Cabins we haven't measured are listed separately below rather than assumed either way.
Routes Where You Might Not Get a Flat Bed20 routes
Tracked routes where flight data shows a business cabin that doesn't go flat actually operating. The percentage is the highest observed share for a non-flat cabin on that route — how often the risk is real, not theoretical.
Cabins We Haven't Measured1
These business cabins are in our catalogue but carry no recline or bed-length figure, so we can't say whether they go flat. They are excluded from every list above — an unmeasured cabin is not evidence that it isn't flat.
How We Decide What Counts
A cabin counts as lie-flat when its seat reclines to a fully horizontal bed. Angled-flat seats — the ones that recline a long way but leave you sliding downhill — do not count, and neither do cradle recliners, however generous the pitch. That is the same distinction the seat-dimension score uses: flat cabins are scored on bed length, everything else on recline angle. A cabin with neither figure on record is unclassified, never assumed.
The route percentages come from tracked flight history resolved to individual aircraft registrations, so they describe what has actually been flying rather than what is scheduled — on the 261 routes we track, which is not every route these airlines fly. Looking up a specific flight number gives the sharpest answer for a booking you are about to make.
