Η πτήση μας έχει προορισμό την Αθήνα.

• Η = the
• πτήση = flight
• μας = our
• έχει = has
• προορισμό = destination
• την Αθήνα = Athens

So the sentence is literally something like The flight our has destination Athens, but in natural English it means Our flight is bound for Athens or Our flight’s destination is Athens.

Greek often uses έχω (to have) in expressions where English might prefer to be.

So:

• Η πτήση μας έχει προορισμό την Αθήνα = literally Our flight has Athens as its destination
• A more English-like structure in Greek would be: Ο προορισμός της πτήσης μας είναι η Αθήνα = The destination of our flight is Athens

Both are correct, but έχει προορισμό... is a very normal and natural way to say it in Greek.

In Greek, possessive words like μου, σου, μας, σας, τους usually come after the noun.

So:

• η πτήση μας = our flight
• το σπίτι μου = my house
• οι φίλοι τους = their friends

This is just the normal Greek pattern. English puts the possessive before the noun; Greek often puts it after.

μας is the weak possessive form meaning our.

It can also mean us in other contexts, so its exact meaning depends on the sentence.

Here, because it follows a noun, it means our:

• η πτήση μας = our flight

But in another sentence:

• μας βλέπει = he/she sees us

So the function changes with context.

Because Αθήνα is the direct object of έχει προορισμό in this structure, so it appears in the accusative case, and the article also changes accordingly.

• nominative: η Αθήνα
• accusative: την Αθήνα

Greek very often uses the definite article with place names, especially city names:

• η Αθήνα
• η Θεσσαλονίκη
• τον Πειραιά

So την Αθήνα is the natural accusative form here.

Because Greek articles change according to case, not just gender and number.

Αθήνα is a feminine singular noun, and its article changes like this:

• η Αθήνα = nominative, used for the subject
• της Αθήνας = genitive
• την Αθήνα = accusative, used for the object

In this sentence, Athens is not the subject. It is the destination, expressed as the object of the phrase έχει προορισμό, so Greek uses την Αθήνα.

προορισμό is in the accusative singular.

The base form is:

• ο προορισμός = the destination

After the verb έχει (has), Greek uses the accusative for the direct object:

• έχει προορισμό = has a destination

So:

• nominative: ο προορισμός
• accusative: τον προορισμό / without article here: προορισμό

That is why you see προορισμό and not προορισμός.

Greek does not always need an article in this kind of expression.

έχει προορισμό την Αθήνα means roughly has Athens as destination. This sounds natural in Greek without the article before προορισμό.

You could sometimes see article use in other structures, but here the article is normally omitted.

So:

• έχει προορισμό την Αθήνα = natural
• έχει τον προορισμό... would mean something different and would usually sound odd in this sentence

Yes, sometimes Greek can omit possessive words if the context makes ownership obvious, but in this sentence μας is important because it tells you whose flight it is.

Compare:

• Η πτήση έχει προορισμό την Αθήνα = The flight is bound for Athens
• Η πτήση μας έχει προορισμό την Αθήνα = Our flight is bound for Athens

Without μας, the sentence becomes more general.

Greek word order is more flexible than English, but the version you have is the most neutral and natural one.

Normal:

• Η πτήση μας έχει προορισμό την Αθήνα.

You may also hear variations for emphasis, such as:

• Την Αθήνα έχει προορισμό η πτήση μας.

That puts extra focus on Athens.

So the sentence can change order, but not randomly. The original order is the safest one for learners.

Yes, but it is slightly different in tone.

• Η πτήση μας πάει στην Αθήνα = Our flight goes to Athens
• Η πτήση μας έχει προορισμό την Αθήνα = Our flight’s destination is Athens / Our flight is bound for Athens

The version with προορισμό sounds a bit more formal or informational, like airport or travel language.

A simple pronunciation guide is:

i PTI-si mas E-hi pro-o-riz-MO tin a-THI-na

A few helpful notes:

• πτήση sounds roughly like PTEE-see
• έχει is pronounced E-hi
• Αθήνα is a-THEE-na
• The stressed syllables are:
  • πτήση
  • έχει
  • προορισμό
  • Αθήνα

No. They are different case forms of the same noun.

• η Αθήνα = Athens in the nominative
• της Αθήνας = of Athens
• την Αθήνα = Athens in the accusative

So in your sentence, την Αθήνα is correct because the noun is in the accusative case.
