Most Boeing 767s fly without a built-in crew bunk, so airlines improvise rest through a tiered workaround: certified in-cabin rest seats where the aircraft has none, blocked premium or economy seats when the layout needs it, and galley jumpseats when the cabin sells out.
The same patchwork shows up on other bunk-free types — Air Canada‘s documented arrangement covers the A330, not the 767. For travelers, the quiet effect is real: a premium cabin can read as sold out while seats sit empty, held back for crew.
The Boeing 767 was drawn up for an era when “long-haul” meant something shorter than it does today. The result: most original 767 configurations shipped without the concealed crew-bunk modules that later widebodies treat as standard. Airlines kept flying the type on long sectors anyway, which forced a plainer question — where does the crew actually rest?
The answer is less a single fix than a tiered system. Certified rest seats with added recline and foot support come first; blocked premium or economy rows step in when those aren’t installed; galley jumpseats absorb the overflow when the cabin sells out. The practice is type-agnostic — Air Canada‘s documented arrangements target the A330 and A321XLR, and British Airways‘ policy covers select 787-10 and 777-200 aircraft — so the 767 is the anchor, not the exception.
Each rung of that ladder quietly shapes what passengers can book.
The regulatory line: three classes of rest, no single hour threshold
The Federal Aviation Administration‘s AC 117-1 guidance doesn’t speak in terms of “bunk or nothing.” It sorts crew rest facilities into three classes under Part 117.
Class 1 covers a full flat bed, walled off from the flight deck and the passenger cabin alike; the FAA’s advisory text even sketches one at 78 by 30 inches. Class 2 describes a cabin seat that goes flat or close to it, with at least a curtain separating it from passengers.
Class 3 is the workhorse of the bunk-less fleet: a certified in-cabin rest seat that reclines at least 40 degrees and offers leg and foot support.
The UK Civil Aviation Authority tightens the geometry in its retained CS FTL.1.205 definitions. Under those UK definitions, a Class 2 seat has to offer leg and foot support, a minimum 45 degrees of recline, 55 inches of pitch, and 20 inches of width.
Class 3 there still requires at least 40 degrees of recline — but without the added pitch and width the Class 2 category demands.
The trap for anyone looking for a clean rule: no single FAA or UK hour figure in the reviewed material makes a Class 1 bunk mandatory across the board. What the rules do instead is tie the facility class an operator installs to the maximum flight-duty period an augmented crew may work.
The substitute hierarchy airlines actually use
Strip away the class definitions and airlines face a plainer problem: where does the crew sleep on a bunk-less aircraft? The answers form a hierarchy, and the highest rungs consume sellable space.
British Airways shows the top of that ladder. On selected non-bunk 787-10 and 777-200 aircraft, cabin crew may rest in vacant First or Club World seats, with galley high-comfort attendant seats as the fallback once the premium cabins sell out. The policy change was reported to take effect in late June 2026 — and the material reviewed doesn’t confirm a matching 767 arrangement.
Air Canada runs the same playbook on different metal. Under LOU 61 — published by the AC Component — specified non-bunk A330 and A321XLR flights set aside a dedicated economy-seat bank for cabin rest on sectors running 7 hours 30 minutes to 11 hours 30 minutes block-to-block.
The improvisation isn’t new, but the reviewed material doesn’t confirm a current 767-specific arrangement from any operator — the documented cases sit on other types.
| Carrier | Aircraft type verified | Crew-rest arrangement | Current-status note |
|---|---|---|---|
| British Airways | 787-10 and selected 777-200 aircraft | Vacant First or Club World passenger seats when available; galley high-comfort attendant seats when full | Current 2026 policy reported; a comprehensive 767 configuration was not verified |
| Air Canada | Non-bunk A330 and A321XLR | Dedicated economy-seat bank; additional economy seats held as last-sold inventory | LOU 61 applies to specified flights and distinguishes non-guaranteed last-sold seats from dedicated seats |

Why a premium cabin can read sold out while seats sit empty
The quietest consequence of all of this is the one travelers feel at checkout. A premium cabin can display as sold out while several seats sit visibly empty mid-flight. The gap isn’t an airline error; it’s soft-blocking for crew rest.
LOU 61 makes the distinction unusually explicit. The dedicated economy-seat bank is protected for crew use; the separate last-sold seats are, in the AC Component document’s own words, “not dedicated or blocked-off” and “not guaranteed.”
A traveler looking at either one sees an empty seat on the map. The promises attached are different.
What the reviewed material does not document is the next layer down: the reservation-system commands, upgrade logic, or real-time seat-map updates behind those soft blocks. That machinery remains a black box — and precisely the terrain where a “sold out” label can outlast the actual cabin.
The APFA substitution ladder makes the same point from the other direction. On a long sector, a business-class seat that leaves inventory for a fatigue-management substitution never reaches the upgrade pool. Passengers aren’t displaced; they’re simply never offered the seat in the first place.
How a passenger seat becomes a crew-rest facility
None of this is as simple as a crew member picking an empty row. Under FAA rules, each aircraft’s rest facility has to be qualified through an aircraft-specific analysis and then authorized in the operator’s OpSpec A117 before augmented operations can be flown.
A Class 3 reclining seat isn’t a rest facility because it looks comfortable; it’s a rest facility because the operator analyzed the specific cabin, matched it to the flight-duty rules, and got the authorization on file. Those findings then turn into booking rules: certain rows are locked as dedicated rest seats, others are held back as last-sold inventory, and the remainder open up only when demand requires it.
The result is a cabin governed by authorization as much as by demand — which is why the seat map and the cabin you board so often tell different stories.
What this means for you
If you’re booking a long sector on a bunk-less type, three patterns are worth watching.
First, don’t read a sold-out premium cabin as a literal count of occupied seats — a soft block can hold space for crew while the cabin shows full. Second, upgrades can lag behind reality for the same reason; a seat never released to inventory can’t be won at the gate. Third, on Air Canada LOU 61 flights, the last-sold economy banks are not protected seats — a marketed “available” seat there is genuinely conditional, not a guarantee.
None of this means passengers get bumped. The documented arrangements are conditional inventory protection, not displacement. What changes is what you can select, upgrade into, or plan around before you fly.
Key terms
- Part 117
- Part 117 is the U.S. federal rule that sets flight-time limits and rest requirements for airline flightcrew. Its guidance, FAA Advisory Circular AC 117-1, sorts crew rest facilities into three classes and ties the class an operator installs to the maximum flight-duty period an augmented crew may work. For the bunk-less 767, that link matters: no single hour figure in Part 117 forces an operator to fit a dedicated bunk, so a certified in-cabin seat can satisfy the rule instead.
- Class 3 rest facility
- A Class 3 rest facility is a certified in-cabin seat that reclines at least 40 degrees and provides leg and foot support. It is the lowest of the three rest-facility classes under Part 117, below the flat Class 1 bunk and the curtained, near-flat Class 2 seat. Because it needs no separate compartment, it is the class most bunk-less 767 operators rely on when a full sleeping module isn’t installed.
- OpSpec A117
- OpSpec A117 is an FAA operations specification that authorizes an operator to use onboard crew rest facilities for augmented operations. Before it is issued, each aircraft’s rest facility must pass an aircraft-specific qualification analysis. That requirement is why a comfortable seat alone doesn’t qualify as crew rest on a 767 — the authorization has to be on file first.
- LOU 61
- LOU 61 is a Letter of Understanding between Air Canada and the Air Canada Component of CUPE, its cabin crew union. It covers specified non-bunk A330 and A321XLR flights with scheduled block-to-block times greater than 7 hours 30 minutes but less than 11 hours 30 minutes. The agreement separates dedicated crew-rest seats from last-sold seats that carry no guarantee, which is why an empty seat on those flights may not be bookable.
- CS FTL.1.205
- CS FTL.1.205 is the UK Civil Aviation Authority’s retained definition of flight-time-limitation terms, including crew rest facilities. It sets stricter geometry than the FAA: a UK Class 2 seat needs at least 45 degrees of recline, 55 inches of pitch and 20 inches of width, while Class 3 still requires 40 degrees. For a bunk-less 767 flying under UK rules, that means the seat an operator installs has to clear a higher bar than the FAA’s minimum.
Questions? Answers.
How much rest can a single cabin crew member take in a dedicated economy-seat bank on Air Canada LOU 61 flights, and how many can rest at once?
Each cabin crew member can rest in the dedicated economy-seat bank for a maximum of one hour. No more than two cabin personnel may rest at one time, though up to four may rest on the A330 when last-sold seats are also available. The Air Canada Component LOU 61 notices provide two dedicated crew-rest seats on the listed A330 flights.
On the flights covered by APFA guidance, how many passenger seats may substitute for an unusable crew bunk, and does flight length change which cabin is used?
APFA guidance permits up to four substitute passenger seats in the seven-to-ten-hour provision and up to five in the over-ten-hour provision. Flight length changes the cabin used: a seven-hour threshold applies to one-for-one premium-economy substitution, while a ten-hour threshold applies to business-class substitution on configured 777 and 787 aircraft.
How many dedicated crew-rest seats does Air Canada provide on the A330 flights listed under LOU 61, and which block times does the arrangement cover?
On the listed A330 flights, Air Canada provides two dedicated crew-rest seats. LOU 61 covers specified non-bunk A330 and A321XLR operations with scheduled block-to-block times greater than 7 hours 30 minutes but less than 11 hours 30 minutes.
