כרטיס העלייה שלי בטלפון, אבל כרטיס העלייה שלה בתיק.

Because Hebrew often leaves out to be in the present tense.

So:

• כרטיס העלייה שלי בטלפון literally looks like My boarding pass on the phone
• but it means My boarding pass is on the phone

This is called a nominal sentence. In the present tense, Hebrew usually does not say is / am / are.

If you wanted the past or future, then Hebrew would use a verb:

• כרטיס העלייה שלי היה בטלפון = My boarding pass was on the phone
• כרטיס העלייה שלי יהיה בטלפון = My boarding pass will be on the phone

כרטיס העלייה is a construct phrase (called smikhut in Hebrew).

Literally:

• כרטיס = card / ticket
• עלייה = going up / ascent / boarding

Together, כרטיס העלייה means boarding pass.

This pattern is very common in Hebrew: two nouns are joined together, and the first one becomes linked to the second.

Other examples:

• בית ספר = school (literally house of book historically, though now just a fixed expression)
• חדר שינה = bedroom
• כרטיס אשראי = credit card

So כרטיס העלייה is not just two separate nouns; it is one combined noun phrase.

Because in a construct phrase, the definiteness of the whole phrase is usually marked on the second noun, not the first.

So:

• כרטיס עלייה = a boarding pass
• כרטיס העלייה = the boarding pass

Even though the ה is attached only to עלייה, the whole phrase becomes definite.

This is a key Hebrew pattern:

• ספר ילד would not be normal for the boy’s book
• ספר הילד = the boy’s book

Likewise:

• כרטיס העלייה שלי = my boarding pass

The phrase is definite both because of the possessive שלי and because this is the normal structure of the fixed expression.

Because Hebrew possessive words like שלי usually come after the noun.

So:

• הספר שלי = my book
• התיק שלה = her bag
• כרטיס העלייה שלי = my boarding pass

This is different from English, where my comes before the noun.

A very literal breakdown is:

• כרטיס העלייה שלי = the boarding pass of mine

That sounds odd in English, but it is a normal Hebrew structure.

No, שלי does not change according to the gender or number of the thing being possessed.

It changes according to the owner.

So:

• שלי = my / mine
• שלך = your / yours
• שלו = his
• שלה = her

Examples:

• הספר שלי = my book
• המכונית שלי = my car

Even though ספר is masculine and מכונית is feminine, שלי stays the same.

In your sentence:

• כרטיס העלייה שלי = my boarding pass
• כרטיס העלייה שלה = her boarding pass

The change from שלי to שלה tells you who owns it.

They show different possessors:

• שלי = my / mine
• שלה = her / hers

So the sentence contrasts two people:

• כרטיס העלייה שלי בטלפון = My boarding pass is on the phone
• אבל כרטיס העלייה שלה בתיק = but her boarding pass is in the bag

This kind of contrast is very common in Hebrew, especially with אבל (but).

The letter ב here is the preposition in / at / on, depending on context.

So:

• טלפון = phone
• ב + טלפון = in/on the phone

In this sentence, בטלפון means something like on the phone or on my phone, depending on the context.

Hebrew uses ב in many places where English may use in, on, or at.

Examples:

• בבית = at home / in the house
• במכונית = in the car
• בטלפון = on the phone / in the phone

Because when ב joins a definite noun with ה (the), they contract.

So:

• ב + ה + טלפון becomes בטלפון
• ב + ה + תיק becomes בתיק

This is a very common Hebrew contraction.

Compare:

• בטלפון = in/on the phone or in/on the telephone
• בתיק = in the bag

If the noun is indefinite, there is no ה:

• בתיק? careful — this written form usually looks the same, but context tells you whether it is definite or not. In many learning examples, בתיק often means in the bag because it comes from ב + התיק.

In your sentence, בתיק is most naturally understood as in the bag.

Not necessarily.

בתיק by itself means in the bag. The sentence does not explicitly say that the bag is hers.

The possessive שלה applies to כרטיס העלייה:

• כרטיס העלייה שלה = her boarding pass

Then:

• בתיק = in the bag

So the full meaning is:

• her boarding pass is in the bag

In real context, the bag might be hers, but the Hebrew sentence does not directly mark that.

If you wanted to say in her bag, you could say:

• בתיק שלה

אבל means but.

It connects the two contrasting parts:

• כרטיס העלייה שלי בטלפון
• אבל כרטיס העלייה שלה בתיק

Hebrew often places אבל at the beginning of the second clause, just like English but.

So the structure is:

• statement 1
• אבל
• statement 2

This is very straightforward and common.

Yes. Both halves are complete and natural in Hebrew.

The pattern is:

• [noun phrase] + [location]
• [noun phrase] + [location]

So:

• כרטיס העלייה שלי בטלפון
• אבל כרטיס העלייה שלה בתיק

This is perfectly normal Hebrew.

Hebrew often avoids repeating words that are understood, especially the present-tense is.

It is a standard expression for boarding pass, but it also follows a regular Hebrew pattern that you can use elsewhere.

So yes, it is both:

1. a common fixed phrase you should learn as a unit, and
2. an example of a productive grammar pattern

Other useful examples:

• כרטיס טיסה = flight ticket
• כרטיס אשראי = credit card
• חדר מלון = hotel room

So learning כרטיס העלייה helps you both with vocabulary and with the construct pattern.

Yes, in a very literal sense בטלפון could be thought of as in the phone, but in natural English the best translation is usually on the phone.

Hebrew ב does not match English prepositions one-to-one. The exact English choice depends on what sounds natural.

So if a boarding pass is stored digitally, English usually says:

• on my phone

Even though the Hebrew uses ב.

That is normal and not something to worry about too much: Hebrew and English divide up in / on / at differently.
