✕Common Mistakes

  • Preciso de mudar minha reserva.

    ‘Preciso’ already implies necessity; do not add the preposition ‘de’ before the infinitive.

  • Preciso mudar sua reserva.

    If you’re speaking about a reservation belonging to someone else, use ‘sua reserva’ (your reservation).

  • Preciso trocar minha reserva.

    Avoid using ‘trocar’ here; ‘trocar’ means ‘to exchange’ and sounds odd for changing a booking.

↔Alternatives

  • Quero alterar minha reserva.

    I want to alter my reservation.

  • Preciso modificar a minha reserva.

    I need to modify my reservation.

  • Preciso mudar a data da minha reserva.

    I need to change the date of my reservation.

Cultural Tip

In Brazil, it’s common to confirm the reservation number before asking for changes. Politeness matters, so adding ‘por favor’ or ‘desculpe incomodar’ can make the request sound more courteous, especially when speaking with customer service agents.
