“Flew” and “flown” are both forms of the verb fly, but they are not interchangeable. The correct choice depends on the tense and sentence structure. Flew is the simple past tense of fly, while flown is the past participle and normally appears with helping verbs such as has, have, or had. For example, “The bird flew away” is correct, while “The bird has flown away” is correct.
Understanding the difference between flew and flown is important for students, English learners and anyone who wants to write or speak naturally. The two words describe the same basic action, but they perform different grammatical jobs. Once you understand how simple past and past participle forms work, choosing between flew and flown becomes much easier.
Quick Answer: Flew vs Flown
Flew is the simple past form of fly, used for a completed action in the past: “The plane flew over the city.” Flown is the past participle, used with helping verbs such as has, have, and had: “The plane has flown over the city.” So, use flew alone for simple past and flown with a helping verb.
Why Do People Confuse Flew and Flown?
People often confuse these words because they are both forms of the irregular verb fly.
Unlike regular verbs, fly does not simply add -ed to form its past tense. Instead, it changes form:
- Fly → present tense
- Flew → simple past
- Flown → past participle
The main difficulty is recognizing when English requires the simple past and when it requires the past participle.
Compare these sentences:
- I flew to London last year.
- I have flown to London several times.
Both sentences describe flying, but the grammar is different.
What Does “Flew” Mean?
Flew is the simple past tense of fly.
Use flew when talking about an action that happened and was completed in the past.
Examples of “Flew”
- The bird flew across the garden.
- We flew to Dubai last summer.
- The airplane flew above the clouds.
- She flew home after the meeting.
- The butterfly flew away.
You can often use flew with a specific past-time expression such as:
- yesterday
- last night
- last week
- last year
- two days ago
- in 2024
- when I was young
For example:
We flew to Turkey last year.
Here, the action happened at a specific time in the past, so flew is appropriate.
What Does “Flown” Mean?
Flown is the past participle of fly.
A past participle generally does not work as the main verb by itself when you mean a completed action. It usually needs a helping verb.
Common helping verbs used with flown include:
- has
- have
- had
- be
- been
The most common structures are:
has/have + flown

Common Mistakes With Flew and Flown
Mistake 1: Using “flown” as simple past
Incorrect:
I flown to Paris yesterday.
Correct:
I flew to Paris yesterday.
Because yesterday identifies a completed past action, the simple past flew is needed.
Mistake 2: Using “flew” after “have”
Incorrect:
I have flew to London.
Correct:
I have flown to London.
After have or has in the present perfect, use the past participle flown.
Mistake 3: Using “flew” after “had”
Incorrect:
They had flew home.
Correct:
They had flown home.
The structure is had + past participle, so flown is required.
Mistake 4: Thinking “flown” is always wrong
Some learners see flown and assume flew should always be used because it is the familiar past form.
But flown is essential in perfect and passive constructions.
For example:
She has flown to Japan.
Here, flew would be incorrect.

Use this simple rule:
Flew = flew by itself.
