The Pilot or Flight Attendant Is or Are — Which One Is Correct?
You're writing a company policy. It says something like: "If the pilot or flight attendant is unavailable, the backup crew will be called.Even so, is it "is" or "are"? Practically speaking, " But something feels off. Your brain keeps toggling between the two, and now you're second-guessing everything you've ever known about grammar.
Here's the short version: when two singular subjects are joined by "or," you use a singular verb. So "the pilot or flight attendant is unavailable" is correct.
But — and this is where it gets interesting — the full picture is a bit more nuanced than a single rule. Let me explain why this works, when it gets tricky, and what to do when your sentence involves mixed singulars and plurals Simple, but easy to overlook..
What Is Subject-Verb Agreement with "Or"?
If you're connect two subjects with "or" (or either...or, neither...nor), you're dealing with what's called proximity agreement — the verb agrees with the subject closest to it Most people skip this — try not to..
In most cases, both subjects joined by "or" are singular, so you use a singular verb:
- "The pilot or the flight attendant is responsible for the safety briefing."
- "Either the captain or the first officer makes the final decision."
The logic here is simple: each subject individually is singular, so the verb stays singular. You're essentially saying "this one OR that one" — never both at the same time.
The Proximity Rule Explained
The verb "agrees" with the nearest subject. This is why it matters which subject comes first:
- "The pilot or the flight attendants are needed." (plural "are" because "attendants" is plural)
- "The flight attendants or the pilot is needed." (singular "is" because "pilot" is singular)
See how the position changes everything? That's proximity agreement in action.
Why Does This Matter?
Because getting it wrong can make your writing look careless. And in professional contexts — like policies, contracts, or official communications — that matters It's one of those things that adds up..
But there's a bigger reason to understand this rule: it protects you from awkward sentences. Imagine writing "The pilot or the flight attendants are responsible" when you mean one person, not multiple. The plural verb implies both groups are involved, which changes the meaning entirely Not complicated — just consistent..
In legal and aviation contexts especially, precision matters. A policy that says "the pilot and flight attendant are required to attend" means both must be there. Change "and" to "or," and the requirement shifts to "one or the other." The verb has to match that meaning.
How It Works in Real Sentences
Let's break this down with some practical examples:
Two Singular Subjects (Most Common)
At its core, the straightforward case. Both subjects are singular, so the verb is singular:
- "If the pilot or the co-pilot needs a break, they should notify air traffic control."
- "Neither the captain nor the lead flight attendant is required to be on the tarmac."
Notice how "neither...nor" follows the same rule. The verb still agrees with the nearest subject The details matter here..
One Singular, One Plural
This is where people get stuck. The key is to match the verb to whichever subject is closest to it:
- "The pilot or the cabin crew are required to attend." (plural "are" matches "crew")
- "The cabin crew or the pilot is required to attend." (singular "is" matches "pilot")
Here's the honest truth: most style guides recommend rewriting these sentences entirely to avoid confusion. "Either the pilot or the cabin crew members are required to attend" is grammatically fine, but it's clunky. A cleaner fix: "Either the pilot or a member of the cabin crew is required to attend Nothing fancy..
People argue about this. Here's where I land on it.
Collective Nouns and Team Terms
Words like "crew," "team," "staff," and "management" can be tricky. In American English, they're typically singular ("the crew is on board"). In British English, they often take plural verbs ("the crew are ready").
Either way, the proximity rule still applies. "The pilot or the crew is responsible" treats "crew" as singular. If you're writing for a British audience or publication, you'd write "the pilot or the crew are responsible.
Common Mistakes People Make
Mistake #1: Making the Verb Plural Just Because "Or" Feels Like "And"
This is the most common error. Writers hear "or" and think "multiple options," so they default to plural verbs. But "or" means one or the other — not both. The verb should reflect that And that's really what it comes down to..
Wrong: "The pilot or the flight attendant are required to sign the document." Right: "The pilot or the flight attendant is required to sign the document."
Mistake #2: Ignoring Proximity When Subjects Differ in Number
When one subject is singular and one is plural, the position of the subjects determines the verb. Many writers don't realize this and just pick one form and stick with it, regardless of what comes next to the verb.
Wrong: "The pilot or the flight attendants are responsible for this." Right: "The pilot or the flight attendants is responsible for this." (Wait — actually, this depends on which subject is closer. If "attendants" is closer, it should be "are." Let me reconsider.)
Actually, let me be more precise here. The proximity rule says the verb agrees with the nearest subject:
- "The pilot or the flight attendants are needed." (are agrees with "attendants")
- "The flight attendants or the pilot is needed." (is agrees with "pilot")
But here's the thing — this sounds awkward either way. That's why the best advice is to restructure the sentence so it doesn't create this problem in the first place That's the part that actually makes a difference. Still holds up..
Mistake #3: Treating "Either/Neither" as Plural
Words like "either" and "neither" are singular. Plus, "Either option is valid. Practically speaking, " "Neither pilot is available. " Don't let the "two options" meaning trick you into using plural verbs That alone is useful..
Practical Tips for Getting It Right
1. Identify the subject closest to the verb. That's the one your verb needs to match.
2. When in doubt, rewrite. If you have a singular-plural mismatch that sounds awkward, restructure the sentence. "One of the following — the pilot or the flight attendants — is required to attend" is clearer than trying to force agreement Worth keeping that in mind..
3. Watch for "neither...nor" and "either...or." These follow the same proximity rule. "Neither the captain nor the co-pilot is available" (singular matches "co-pilot"). "Neither the co-pilot nor the captains are available" (plural matches "captains") The details matter here. Surprisingly effective..
4. Consider your audience. If you're writing for a British publication, you'll have more flexibility with collective nouns taking plural verbs. In American English, stick with singular for team terms.
5. Read it aloud. If a sentence sounds wrong, it probably is. Grammar rules exist because they reflect how language is supposed to flow. If "the pilot or flight attendant are" sounds clunky to your ear, trust that instinct.
FAQ
Is "the pilot or flight attendant is" always correct?
Yes, when both subjects are singular. "The pilot or the flight attendant is responsible" is grammatically correct because each subject individually takes a singular verb Easy to understand, harder to ignore..
What if one subject is plural?
The verb agrees with the nearest subject. On top of that, "The pilot or the flight attendants are needed" uses "are" because "attendants" is closest to the verb. But consider rewriting for clarity.
Does "either/or" change the rule?
No. "Either the pilot or the co-pilot is in charge" — both are singular, so the verb stays singular Which is the point..
What about "neither...nor"?
Same rule. "Neither the pilot nor the flight attendant is responsible" — singular because both subjects are singular and "attendant" is closest to the verb Took long enough..
Should I use "they" instead to avoid the issue?
Some writers do, especially in informal contexts. "If the pilot or flight attendant is unavailable, they should contact dispatch." This is becoming more accepted, but it can create ambiguity about whether one person or both need to act. In formal writing, stick with the traditional agreement.
The Bottom Line
Here's what it comes down to: when subjects are joined by "or," the verb agrees with the nearest subject. On the flip side, in most practical cases — like "the pilot or flight attendant is" — that means a singular verb. That said, the confusion comes from thinking "or" implies multiple people, but it doesn't. It implies one or the other.
If your sentence gets messy with mixed singulars and plurals, don't force it. Rewrite. Clear communication beats grammatically stubbornness every time.
