“Flew” and “flown” are both forms of the verb fly, but they are not interchangeable. The main difference is their grammatical role: flew is the simple past tense, while flown is the past participle. Understanding when to use each form can help you write and speak more accurately in everyday, academic, professional, and formal situations.
Comparison Overview
Flew and flown both come from the irregular verb fly, which means to move through the air, travel by aircraft, or move quickly through space.
The three principal forms of fly are:
| Verb Form | Word | Example |
| Base form | fly | Birds fly south in winter. |
| Simple past | flew | The bird flew away. |
| Past participle | flown | The bird has flown away. |
The key distinction is simple:
- Flew = simple past
- Flown = past participle
- Have/has/had + flown = perfect constructions
- Be + flown = passive constructions in appropriate contexts
For example:
- She flew to London yesterday. ✅
- She has flown to London several times. ✅
- She has flown to London several times. ❌
Definition of Flew
Flew is the simple past tense of the verb fly.
It describes an action that happened and was completed in the past.
Examples of Flew
- The bird flew over the house.
- We flew to Karachi last month.
- The plane flew through the clouds.
- He flew home after the meeting.
- The kite flew high above the field.
The word flew does not normally require an auxiliary verb such as has, have, or had to show the past.
Basic pattern:
Subject + flew + additional information
For example:
They flew to New York yesterday.
Definition of Flown
Flown is the past participle of the verb fly.
Unlike flew, it generally needs an auxiliary or helping verb such as have, has, had, be, or another appropriate auxiliary construction.
Examples of Flown
- She has flown across the country.
- They have flown several times this year.
- He had flown home before the storm arrived.
- The aircraft had flown over the mountains.
- We have flown with that airline before.
The basic perfect-tense pattern is:
Subject + have/has/had + flown
For example:
I have flown on that route before.
Main Differences Between Flew and Flown
The biggest difference between flew and flown is grammatical rather than semantic. Both relate to flying, but they function differently within a sentence.
| Feature | Flew | Flown |
| Verb form | Simple past | Past participle |
| Base verb | Fly | Fly |
| Used alone as a past-tense verb | Yes | No, generally |
| Common auxiliary | Usually none | Have, has, had, etc. |
| Example | She flew yesterday. | She has flown before. |
| Main function | Completed past action | Perfect or participial construction |
Flew Describes a Past Action
Use flew when simply talking about something that happened in the past.
We flew to Dubai last summer.
The action occurred in the past, and the sentence does not use have, has, or had.
Flown Works With Helping Verbs
Use flown when the sentence requires the past participle.
We have flown to Dubai several times.
Here, have + flown creates the present perfect tense.
Compare These Sentences
I flew to Islamabad yesterday.
I have flown to Islamabad many times.
The first sentence identifies a completed past event. The second describes an experience or action connected to the present.
Flew vs. Flown in Different Tenses
Understanding tense makes the distinction much easier.
Simple Past
Use flew.
She flew to Paris last week.
Present Perfect
Use has/have flown.
She has flown to Paris several times.
Past Perfect
Use had flown.
She had flown to Paris before moving there.
Future Perfect
Use will have flown.
By Friday, she will have flown three times this month.
The important point is that flown is used as the past participle, while flew functions as the simple past form.
Grammar Guide
Fly is an irregular verb. This means its past forms do not follow the regular -ed pattern.
Its principal parts are:
fly → flew → flown
These forms have different grammatical functions.
- Fly — base form
- Flew — simple past
- Flown — past participle
How Each Term Is Used in Sentences
Flew
Use flew for a completed action in the past.
Pattern:
Subject + flew + complement.
Examples:
The plane flew over the ocean.
Sarah flew home yesterday.

Common Mistakes Learners Make
One of the most common mistakes is using flew after has, have, or had.
Incorrect:
She has flew to Canada.
Correct:
She has flown to Canada.
Another common mistake is using flown as the simple past without an auxiliary.
Incorrect:
Yesterday, we flown to Lahore.
Correct:
Yesterday, we flew to Lahore.
Learners may also incorrectly assume that flown can replace flew because both refer to past flying. Their meanings are related, but their grammatical functions differ.
Simple Rules to Remember
A useful rule is:
Yesterday = flew.
Have/has/had = flown.
For example:
- We flew yesterday.
- We have flown before.
- We had flown there previously.
Another helpful way to remember the sequence is:
Fly → Flew → Flown
Think of these as:
Present → Past → Past participle
Quick Tips for Writing and Speaking
- Use flew when describing a straightforward past event.
- Use flown after have, has, or had when forming perfect tenses.
- Never use has flew or have flew.
- Remember the irregular verb sequence: fly, flew, flown.
- Look for a helping verb before choosing flown.
- If you are describing something that happened at a specific past time, flew is often appropriate.
When to Use Each One
Use Flew When Talking About a Completed Past Event
We flew to London last Monday.
Use Flew With a Specific Past Time
She flew home yesterday.
They flew to Rome in 2024.
Use Flown With Have or Has
I have flown on this airline before.
Use Flown With Had
He had flown home before the announcement was made.
Use Flown for Past Experiences
She has flown internationally many times.
The exact tense depends on what the sentence is trying to communicate.
When NOT to Use Each One
Do Not Use Flew After Have, Has, or Had
Incorrect:
I have flew to Canada.
Correct:
I have flown to Canada.
Do Not Use Flown as the Simple Past
Incorrect:
We flown to New York yesterday.
Correct:
We flew to New York yesterday.
Do Not Confuse the Forms
The fact that flew and flown both refer to past actions does not mean they can be substituted for each other.
Compare:
He flew home yesterday.
He has flown home.
The first uses simple past. The second uses the present perfect.
Flew or Flown in Common Expressions
Both forms can appear in many expressions involving air travel and movement.
Flew Around the World
They flew around the world last year.
Have Flown Around the World
They have flown around the world several times.
Flew Home
She flew home after the conference.
Has Flown Home
She has flown home already.
Flew Over
The helicopter flew over the stadium.
Has Flown Over
The helicopter has flown over the stadium several times.
Flew or Flown for Air Travel
Both forms are common when discussing airplane travel.
Use flew when describing a particular completed trip:
I flew to Istanbul last year.
Use flown when discussing experience or an action connected to another time:
I have flown to Istanbul three times.
The distinction is therefore based on the sentence’s tense and structure, not on whether an airplane or another flying object is involved.
Flew or Flown for Birds and Animals
The same grammatical distinction applies to birds and flying animals.
Simple past:
The eagle flew across the valley.
Present perfect:
The eagle has flown across the valley several times.
Past perfect:
The eagle had flown away before we arrived.
The subject does not change the rule. Whether the subject is a person, bird, insect, aircraft, or fictional creature, the verb forms follow the same grammatical principles.
When to Use “Flew” in Writing
Flew is especially useful when writing narratives and describing events in chronological order.
For example:
The pilot checked the instruments, started the engines, and flew toward the coast.
It works naturally when the writer is presenting a sequence of completed past events.
When to Use “Flown” in Writing
Flown is useful when writing about experience, previous events, or actions completed before another point in time.
For example:
The pilot had flown this route many times before.
It is also common in professional, travel, academic, technical, and historical writing when perfect tenses are appropriate.

Understanding flew or flown becomes much easier once you remember that both words are forms of the irregular verb fly, but they serve different grammatical purposes. Flew is the simple past form, so it is used when describing a completed action in the past, such as “She flew home yesterday.” Flown, on the other hand, is the past participle and usually appears with helping verbs such as have, has, or had, as in “She has flown home before.” The key is to pay attention to the tense and the words surrounding the verb.
If you are talking about a specific past event, flew is generally the correct choice. If your sentence uses a perfect tense, flown is needed. Remembering fly → flew → flown will help you use these forms confidently in everyday conversation, professional writing, and academic work.
