PHP cURL not returning all results - php

Question

I have a very strange problem. I am trying to return an array from a JSON GET request using the Skyscanner API.
The Skyscanner URL I am generating and using in the cURL is: http://partners.api.skyscanner.net/apiservices/browseroutes/v1.0/DE/EUR/de-DE/HAM/PT/2016-12?apiKey=API_KEY
It returns 3 quotes but when I am using a JSON editor like http://www.jsoneditoronline.org/ it gives me 9 quotes!!!
Why does it show less quotes in my solution? And how do I get all quotes???
<?php
$cities = array("HAM");
$countries = array("PT");
$url_api = "http://partners.api.skyscanner.net/apiservices/browseroutes/v1.0/DE/EUR/de-DE/";
$api_key = "API_KEY_HERE";
$next_month = date('m')+1;
if ($next_month=="13") {
$this_year = date('Y')+1;
$next_month = "01";
} else {
$this_year = date('Y');
}
foreach($cities as $city){
foreach($countries as $country){
$url = $url_api.$city."/".$country."/".$this_year."-".$next_month."?apiKey=".$api_key;
$ip = "218.255.245.210";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_POST, false);
curl_setopt($ch, CURLOPT_ENCODING, 'gzip');
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Accept: application/json', 'X_FORWARDED_FOR: '.$ip));
curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4 );
$data = curl_exec($ch);
$response = json_decode($data);
echo $url."<br/>";
$quotes = $response->Quotes;
foreach($quotes as $quote){
echo $quote->QuoteId.". ";
echo $quote->Direct."<br/>";
}
}
}
?>
