There is no global ladder of flight deck ranks. The core is two roles — a captain who holds final legal authority and a first officer who shares the flying — and everything around that pair is defined by each airline rather than by any regulator.
A rank is a job title an employer assigns. A licence is a government certification of competency. That split is why the same title, or the same number of stripes, can mean different things at different carriers.
The band of gold braid on a pilot’s shoulder looks like a ranking chart. It isn’t one.
A three-stripe shoulder board marks an ordinary first officer at one airline. At another, those same three stripes belong to a senior first officer who is allowed to take command during the cruise. The braid looks nearly identical; what it means depends on the airline’s manual, the licence requirements, the type rating, and recurrent checks.
That gap is the whole story. Aviation has a stable core — a captain in command and a first officer sharing the flying — wrapped in a set of additional roles that each operator names and defines for itself.
Regulators certify competency. Airlines hand out ranks. The two are not the same thing, and the confusion between them is why “first officer” can sound like a junior job at one carrier and a senior one at another.

The roles, and what each one actually means
1. Captain
Final legal authority over the aircraft, crew, and passengers rests with the captain — the pilot in command, who normally sits in the left-hand seat.
That authority doesn’t travel. On a leg where the first officer is physically flying, command still sits with the captain from pushback to shutdown. Airlines hand out the title; a regulator issues the licence underneath it.
Four stripes commonly mark the role. That’s a convention rather than a rule, as Flying By Numbers sets out in its guide to pilot stripes.
2. First officer
Three stripes commonly identify a first officer — the pilot most passengers still call the co-pilot.
First officers are fully qualified pilots, not trainees. They share the flying by alternating between pilot flying and pilot monitoring across legs, so the person at the controls can change while the chain of command does not.
Because the title is an employer’s label, its weight varies by carrier. The licence underneath it comes from a government authority, and the two don’t map neatly onto each other.
3. Senior first officer
No worldwide regulator recognizes the title “senior first officer” — it is a grade each airline invents for its own flight deck.
The pilot still flies and monitors like any other first officer. What can change is cruise authority: some operators clear a senior first officer to take over from the commander mid-flight, but only once the company’s requirements are met.
Those requirements are specific — a type rating, an airline-transport licence, route competence, and recurrent checks. EASA’s ORO.FC.A.201 is the rule that governs a pilot relieving the commander during cruise, and it sits alongside the airline’s own manual rather than replacing it.
| Carrier or system | Published/documented rank titles | Distinct ranks verified | Captain and first-officer insignia | Training or senior marking |
|---|---|---|---|---|
| Generic airline convention | Captain; first officer; second officer or flight engineer; trainee or cadet | 4 grades described as a convention, not a global standard | Usually four stripes for captain and three for first officer | Additional symbols may be operator-specific; no universal marking verified |
| Airline-specific senior-first-officer model | Captain; senior first officer; first officer; second officer or cruise relief pilot where used | At least 3 flight-deck grades documented; exact total varies by airline | Four captain stripes; first-officer assignments vary by operator | Senior-first-officer markings are not globally standardized |

4. Second officer or cruise relief pilot
An augmented flightcrew carries more pilots than the aircraft’s type certificate requires — the FAA’s Part 117 definition of a crew with relief capacity built in.
The extra pilot is there because duty-time limits cap how long a crew can stay on the flight deck, and long sectors run through the hours a pilot would normally be asleep. 14 CFR 117.17 sets the permitted duty periods for augmented operations, and the table attached to it shifts those limits according to how many pilots are aboard.
On modern two-pilot flight decks the second officer has become uncommon, though the role hasn’t vanished everywhere. What the public material does not lay out is a single route into it — no universal pathway into a second-officer or cruise-relief post was verified, which leaves hiring and progression to the employer.
5. Training captain or check airman
Experienced captains can take on added duties as training captains or check airmen — mentoring, evaluating, or managing other pilots.
The role is layered on top of command, not a step above it. A check airman may run line checks or type-rating assessments while still flying the line as a captain.
Uniforms often flag the job with extra insignia, and that’s where the visual code gets shaky. Beyond the four-stripe and three-stripe convention, no universal marking was verified — stars, extra braid, and other symbols are operator-specific, so a stripe count read at a boarding gate tells you less than it appears to.
How we picked
This list covers the roles that show up in regulatory definitions and published uniform conventions, not one airline’s org chart. Each entry traces to a verifiable source — FAA Part 117 for augmented crews, EASA’s ORO.FC.A.201 for cruise relief, and documented stripe conventions. Where the material couldn’t confirm a carrier-specific detail, we say so instead of filling the gap.
What this means for you
Command authority is the one thing that doesn’t vary. Whoever is flying the aircraft, the captain is accountable for it — worth remembering when an incident report or a crew introduction names a first officer at the controls.
If a third or fourth pilot boards, the flight is long enough to need relief under duty-time rules. That is a scheduling fact, not a sign that the airline runs a deeper rank structure.
A stripe count is a hint about the operator, not a universal code.
Reporting by
Key terms
- Pilot in command
- The pilot in command is the pilot who holds final legal authority over an aircraft, its crew, and its passengers for the duration of a flight. Regulators issue the licence that carries the designation, while the airline assigns the captain’s title on top of it. For travelers, that means the person flying the aircraft and the person legally responsible for it can be two different people on the same leg.
- Type rating
- A type rating is an endorsement on a pilot’s licence that authorizes the holder to fly a specific aircraft type. It is specific to that model and sits alongside the licence rather than replacing it. Airlines treat it as one of the qualifications a pilot must hold before taking on added duties, such as relieving the commander during cruise.
- Augmented flightcrew
- An augmented flightcrew is a crew carrying more pilots than the aircraft’s type certificate requires. The extra pilots exist so that one qualified pilot can take another’s place during in-flight rest. In this article’s context, an augmented crew is the operational reason a long-haul flight may carry a third or fourth pilot who holds no distinct airline rank.
- EASA ORO.FC.A.201
- EASA ORO.FC.A.201 is the European rule that governs a pilot relieving the commander during cruise. It sets the conditions under which a first officer may take over command in flight, and it works alongside the operator’s own manual rather than replacing it. It is the clearest example in this article of a regulator defining a duty while leaving the rank title to the airline.
- 14 CFR 117.17
- 14 CFR 117.17 is the U.S. federal rule that sets permitted flight-duty periods for augmented operations. Its attached table adjusts those limits according to how many pilots are aboard. For this article, it shows that the regulator governs rest and duty while the airline decides what to call the extra pilots.
Questions? Answers.
What is the order of ranks for airline pilots?
There isn’t a single global order. The stable core is a captain, who holds command, and a first officer, who shares the flying. Around that pair, airlines add their own grades — senior first officer, second officer or cruise relief pilot, training captain — and the number and names of those steps differ by operator. Four stripes commonly mark a captain and three a first officer, but no universal standard was verified.
What does 5 stripes on a pilot mean?
Nothing universal. No global stripe standard was verified, so five stripes isn’t a recognized rank in any worldwide system. Extra braid, stars, or other markings beyond the usual four-for-captain and three-for-first-officer convention are set by individual airlines and mean whatever that operator’s uniform manual says.
Why do long-haul flights sometimes carry an extra pilot?
Flight-time rules cap how long a crew can stay on duty, and long sectors can run through the hours a pilot would normally rest. An augmented flightcrew — one with more pilots than the aircraft’s type certificate requires — lets a qualified pilot take another’s place during in-flight rest. 14 CFR 117.17 sets the permitted duty periods for those augmented operations.
Is ‘senior first officer’ an official rank?
Not in any regulator’s rulebook. It is a title an airline invents for its own flight deck, and the pilot flies and monitors exactly as any other first officer does. Some operators allow a senior first officer to relieve the commander during cruise, but only when the company’s requirements are met — EASA’s ORO.FC.A.201 is the rule that covers a pilot relieving the commander in cruise.
