Questions & Answers about По приезде на конференцию каждый участник должен предъявить билет.
Why is it по приезде here instead of по приезду?
In this specific formal structure meaning 'upon' or 'immediately after', the preposition по requires the Prepositional case (по приезде). You will often hear native speakers use the Dative case (по приезду) in everyday speech, but strict Russian grammar rules consider that a mistake.
Why does приезд take the ending -е here, while other words we learned for 'upon arrival' take -ии (like по прибытии)?
It simply depends on the noun's basic declension. Приезд is a standard masculine noun ending in a consonant, so its Prepositional case ending is -е. Nouns like прибытие (arrival) or окончание (completion) end in -ие, so they take the special Prepositional ending -ии, resulting in по прибытии.
Why do we use the Accusative case for на конференцию instead of the Prepositional case?
Even though the English translation says 'at the conference', the Russian noun приезд (arrival) implies motion toward a destination, just like the verb it comes from (приезжать). Therefore, it requires the directional Accusative case (на конференцию) to show where they are arriving to.
