getting the values received from json_decode

So I have this code

$result = json_decode($output, true);

var_dump($result);

It is generating the following.

    array(3){
  [
    "status"
  ]=>string(9)"completed"[
    "flights"
  ]=>array(2){
    [
      "outbound"
    ]=>array(9){
      [
        "E_0830_1140_2176"
      ]=>array(6){
        [
          "Flight"
        ]=>array(14){
          [
            "class"
          ]=>string(1)"E"[
            "airline"
          ]=>string(2)"G3"[
            "number"
          ]=>string(4)"2176"[
            ---------------------->**"from"**
          ]=>string(3)"GIG"[
            "to"
          ]=>string(3)"FOR"[
            "departure"
          ]=>int(1523532600)[
            "departure_date"
          ]=>string(10)"2018-04-12"[
            "departure_time"
          ]=>string(5)"08:30"[
            "arrival"
          ]=>int(1523544000)[
            "arrival_date"
          ]=>string(10)"2018-04-12"[
            "arrival_time"
          ]=>string(5)"11:40"[
            "flight_time"
          ]=>int(11400)[
            "str_flight_time"
          ]=>string(5)"3h10m"[
            "national"
          ]=>bool(true)
        }

I would like to get the result from "from" by EX and throw it in "echo" and bring it separately so I can style it.
