אם נמצא טיסה ישירה בפעם הבאה, נגיע מוקדם יותר ונהיה פחות עייפים.

This is a very common difference between English and Hebrew.

In Hebrew, when you talk about a real future condition, you usually use the future tense in both parts:

אם נמצא טיסה ישירה, נגיע מוקדם יותר...
= If we find a direct flight, we’ll arrive earlier...

So Hebrew does not follow the English pattern of present after if, future in the main clause. Using the future after אם is normal here.

Here נמצא means we will find.

It is the 1st person plural future form of למצוא = to find.

A helpful clue: it is followed by טיסה ישירה, which is the thing being found. So this is clearly the verb find, not the adjective/participle found / located.

So:

• נמצא = we will find
• not is found
• not is located

Context and sentence structure make that clear.

Because את is used only before a definite direct object.

Here, טיסה ישירה means a direct flight, not the direct flight, so it is indefinite. That is why there is no את.

Compare:

• נמצא טיסה ישירה = we’ll find a direct flight
• נמצא את הטיסה הישירה = we’ll find the direct flight

In Hebrew, adjectives usually come after the noun they describe.

So:

• טיסה = flight
• ישירה = direct

Together: טיסה ישירה = a direct flight

Also, the adjective must agree with the noun in gender and number:

• טיסה is feminine singular
• so the adjective must also be feminine singular
• therefore: ישירה

If the noun were masculine singular, you would get ישיר instead.

Literally, it means something like in the next time/occasion, but the natural English meaning is next time.

Breakdown:

• ב־ = in / at / on
• פעם = time, occasion
• הבאה = the next / coming

So:

• בפעם הבאה = next time

This is a very common Hebrew expression.

Because Hebrew often makes this whole expression definite: the next time.

So both parts are marked as definite:

• בפעם
• הבאה

This is normal with noun + adjective combinations in Hebrew: if the noun phrase is definite, both the noun and adjective are definite.

Compare:

• פעם הבאה = the next time
• טיסה ישירה = a direct flight
  Here there is no ה, so it is indefinite.

Yes. In Hebrew, the verb itself often already tells you the subject, so you do not need to say אנחנו unless you want emphasis.

Here:

• נגיע = we will arrive
• נהיה = we will be

Hebrew also does not need a separate word for will. The future meaning is built into the verb form itself.

So the sentence does not need אנחנו:

• נגיע מוקדם יותר ונהיה פחות עייפים
  = we’ll arrive earlier and be less tired

Hebrew often forms comparisons with יותר = more and פחות = less.

So:

• מוקדם יותר = earlier
  literally: early + more
• פחות עייפים = less tired

Unlike English, Hebrew usually does not add an -er ending to the adjective or adverb. Instead, it often uses a separate word like יותר or פחות.

עייפים is the masculine plural form of tired.

It agrees with the subject we. In Hebrew, when we refers to a mixed group or a group of males, the default adjective form is masculine plural:

• נהיה פחות עייפים = we’ll be less tired

If the speakers were all female, you would say:

• נהיה פחות עייפות

Notice that the verb נהיה stays the same; the adjective changes.

Yes, you could say אם אנחנו נמצא..., but in normal Hebrew that usually sounds unnecessary here.

Because the verbs already show we:

• נמצא = we will find
• נגיע = we will arrive
• נהיה = we will be

Hebrew often omits subject pronouns when they are obvious from the verb. Adding אנחנו would usually give extra emphasis, contrast, or a special tone.
