Nakon uskraćenog ukrcaja provjerite prava putnika i preuzimanje prtljage.

Because nakon normally requires the genitive case in Croatian.

So:

• ukrcaj = boarding
• nakon ukrcaja = after boarding
• nakon uskraćenog ukrcaja = after denied boarding

Both words in that phrase have to match the genitive pattern:

• uskraćeni → uskraćenog
• ukrcaj → ukrcaja

This is one of the most important things to learn with Croatian prepositions: many of them automatically force a certain case.

Uskraćenog is an adjective-like form meaning denied, withheld, or refused.

In this sentence it modifies ukrcaja:

• ukrcaj = boarding
• uskraćeni ukrcaj = denied boarding

Because ukrcaja is in the genitive singular after nakon, the adjective also changes to the genitive singular masculine form:

• nominative: uskraćeni ukrcaj
• genitive: uskraćenog ukrcaja

So uskraćenog is not standing alone; it agrees with ukrcaja in case, gender, and number.

Yes. Provjerite is the imperative form of provjeriti and means check or verify.

It can be used for:

• you all check
• check addressed politely to one person

So in public instructions, notices, websites, or announcements, provjerite is very common because it sounds like a formal instruction:

• Provjerite prava putnika = Check the passengers’ rights

It comes from the verb provjeriti, which is a perfective verb, so it suggests a completed action: check it.

Grammatically, it is the 2nd person plural imperative.

But in Croatian, that same form is also used as a polite singular command, just like French vous or German Sie.

So provjerite can mean:

• check (to several people)
• check (to one person, politely/formally)

In signs and official instructions, Croatian usually uses this form because it is neutral and polite.

Because prava is the plural form of pravo in this sentence.

• pravo = a right
• prava = rights

Here it is the direct object of provjerite, so it is in the accusative plural. For neuter nouns like pravo, the nominative and accusative plural are the same:

• nominative plural: prava
• accusative plural: prava

So:

• provjerite pravo = check the right
• provjerite prava = check the rights

Because putnika is in the genitive plural, showing possession or association:

• prava putnika = the rights of passengers = passengers’ rights

This is a very common Croatian structure:

• cijena karte = the price of the ticket
• vrata auta = the car door / the door of the car
• prava putnika = passengers’ rights

So Croatian often uses noun + genitive noun where English might use 's or a noun used attributively.

Here it means passengers.

The form putnika can be a little confusing because it can represent more than one grammatical function in Croatian. In this sentence, though, it is best understood as genitive plural:

• putnik = passenger
• putnika = of passengers

That is why prava putnika means passengers’ rights, not the passenger’s rights.

Preuzimanje is a verbal noun. It comes from the verb preuzimati / preuzeti and means something like:

• taking over
• collection
• pickup
• in airport language, often reclaim

So preuzimanje prtljage literally means the collecting of baggage, but in natural English it is often rendered as baggage reclaim or baggage claim.

Croatian often uses verbal nouns like this in formal or administrative language.

Because prtljage is in the genitive singular after the verbal noun preuzimanje.

• prtljaga = baggage / luggage
• preuzimanje prtljage = baggage collection / reclaim

This is similar to how other Croatian nouns can take a genitive complement:

• provjera dokumenata = checking of documents
• kupnja karte = purchase of a ticket
• preuzimanje prtljage = collection of baggage

So prtljage is not the main object of the sentence by itself; it belongs inside the phrase preuzimanje prtljage.

Croatian has no articles, so there is no separate word for a/an or the.

That means forms like:

• putnik
• pravo
• prtljaga

do not change depending on definiteness the way English nouns do.

You figure out a vs the from context. In this sentence, the context is official/public information, so English naturally uses the:

• the passengers’ rights
• baggage reclaim

But Croatian itself does not mark that with an article.

Yes, that would also be grammatical.

Croatian word order is relatively flexible, and the original sentence puts the time/condition phrase first:

• Nakon uskraćenog ukrcaja = after denied boarding

That makes the context clear immediately, which is very natural in instructions.

So both are possible:

• Nakon uskraćenog ukrcaja provjerite...
• Provjerite... nakon uskraćenog ukrcaja

The original version sounds especially natural in formal notices because it foregrounds when the instruction applies.

Because Croatian very often expresses this idea with a genitive noun phrase rather than stacking nouns the way English does.

English commonly says:

• passenger rights
• baggage claim
• flight information

Croatian often prefers:

• prava putnika = rights of passengers
• preuzimanje prtljage = collection of baggage
• informacije o letu = information about the flight

So one common adjustment for English speakers is learning not to expect English-style noun piling. Croatian usually builds these relationships with cases or prepositions instead.

Yes, it is a standard formal expression.

At an airport or in legal/passenger-rights contexts, uskraćeni ukrcaj is the usual Croatian equivalent of denied boarding.

It sounds more administrative and official than something more conversational. That matches the tone of the whole sentence, which is written in formal informational language.
