Pri izlazu za ukrcaj pokažite ukrcajnu propusnicu.

Here pri means something like at, by, or upon reaching. In this sentence, pri izlazu za ukrcaj means at the boarding gate / when you are at the boarding gate.

It is a fairly formal, instruction-style word, so it fits airport announcements well.

Because pri takes the locative case, and the locative singular of izlaz is izlazu.

So:

• izlaz = exit / gate
• pri izlazu = at the exit / at the gate

This is a very common thing to watch for in Croatian: the preposition often determines the case.

Literally, it is something like exit for boarding, but in airport English the natural meaning is boarding gate or simply gate.

So even though izlaz usually means exit, in this context izlaz za ukrcaj refers to the place where passengers board the plane.

Here za means for, and in this meaning it takes the accusative case.

The noun ukrcaj is masculine singular inanimate, and for that type of noun, the accusative singular is often identical to the nominative singular. So:

• nominative: ukrcaj
• accusative: ukrcaj

That is why you see za ukrcaj, not a visibly different ending.

Pokažite is the imperative form of the verb pokazati, meaning show.

More specifically, it is the form used for:

• you (plural) — when speaking to more than one person
• you (formal singular) — when politely addressing one person

So it is the normal form for public instructions, announcements, and polite commands.

It can be either:

• formal singular: one person, politely addressed
• plural: more than one person

In signs and announcements, Croatian often uses this form because it works well for the general public.

Compare:

• pokaži = show! (to one person, informal)
• pokažite = show! (to several people, or to one person formally)

Because Croatian usually uses the perfective verb for a single, completed action.

Here the instruction is: show your boarding pass once, at that moment. That matches pokazati → pokažite.

If you used the imperfective pokazivati, it would suggest repeated or ongoing showing, which does not fit this situation as well.

Because this phrase is the direct object of pokažite, so it must be in the accusative case.

The dictionary form is:

• ukrcajna propusnica = boarding pass

In the accusative singular it becomes:

• ukrcajnu propusnicu

Both words change because the adjective and noun must agree:

• ukrcajna → ukrcajnu
• propusnica → propusnicu

Yes, it is a correct and standard term, especially in formal or official travel language.

Depending on region, company, or context, you may also hear other expressions, but ukrcajna propusnica is a very good phrase to know and is exactly the kind of wording you might see in airport instructions.

Yes. Croatian word order is more flexible than English word order.

This sentence puts the location first:

• Pri izlazu za ukrcaj pokažite ukrcajnu propusnicu.

That sounds natural and formal, especially for an instruction sign.

You could also rearrange it, for example:

• Pokažite ukrcajnu propusnicu pri izlazu za ukrcaj.

That would still be understandable, but the original version feels very natural for announcements because it first sets the situation, then gives the instruction.

Yes, very much so.

Several things make it sound formal and official:

• pri instead of a more everyday phrasing
• the polite/plural imperative pokažite
• the official-sounding noun phrase ukrcajna propusnica

So this is exactly the kind of Croatian you would expect on signs, in announcements, or in written instructions at an airport.
