Filter an array via javascript

Good day.

I made a form with inputs with HTML and CSS. Via javascript i put the input data in an array, but now i want to filter in that array.That filter should show me all the input data of the people that ask for one of these destinies. Canarias, Mallorca,Galicia.

let arrViaje = [];

function recoger() {
  let nombre = document.getElementById("name").value
  let origen = document.getElementById("origin").value
  let destino = document.getElementById("destiny").value
  let personas = document.getElementById("people").value
  let fechas = document.getElementById("dates").value

  let viaje = {
    name: nombre,
    origin: origen,
    destiny: destino,
    people: personas,
    dates: fechas
  }
  console.log(viaje)

  arrViaje.push(viaje);
  console.log(arrViaje)

  function filtrar() {
    let ciudadSinFiltrar = "Canarias"
    let ciudad = ciudadSinFiltrar.toLowerCase
    let filteredArray = arrViaje.filter((city) => city.filter(ciudad))
    console.log(filteredArray)
  }
<div class="formulario">
  <form action="">
    <input type="text" class="datos" id="name" placeholder="Nombre">
    <input type="text" class="datos" id="origin" placeholder="Origen">
    <input type="text" class="datos" id="destiny" placeholder="Destino">
    <input type="text" class="datos" id="people" placeholder="Personas">
    <input type="text" class="datos" id="dates" placeholder="Fecha">
  </form>
  <button onclick="recoger()">Mas información</button>
  <button onclick="filtrar()">Filtrar</button>
</div>
