Is the word passagens the same in Brazilian and European Portuguese?

Yes

The word "passagens" is identical in meaning, spelling, and grammar in both Brazilian and Continental Portuguese. The only differences are phonetic:

• Sibilant "s": In Brazil, the "s" at the end of syllables or words is typically pronounced as a dental [s] (like "snake"). In Portugal, this "s" often takes a "chiado" sound, pronounced as [ʃ] (like "ship").
• Vowel reduction: Brazilian Portuguese tends to pronounce unstressed vowels more clearly and openly. In Continental Portuguese, unstressed vowels are often reduced, neutralized, or "swallowed," making the word sound more compressed.
