I use this code for AirlineFlightSchedules

$options = array(  
‘trace’ =\> true,  
‘exceptions’ =\> 0,  
‘login’ =\> ‘user’,  
‘password’ =\> ‘apikey’,  
);  
$client = new SoapClient(‘[https://flightxml.flightaware.com/soap/FlightXML2/wsdl](https://flightxml.flightaware.com/soap/FlightXML2/wsdl)’, $options);

```
	// get the weather.
	$params = array(
		"startDate" => 1499644800, 
		"endDate" => 1499731199 ,
		"origin" => "BVA",
		"destination"	=>"PSA"
		);
	$result = $client->Scheduled($params);

```

But return eror 500, what’s the problem?  
thanks 😐🙂

For the Scheduled method, the allowed query parameters are airport, filter, howMany, offset. So you’d need to change your query params to something like this:

```auto

$params = array(
"airport" => "KIAH", 
"howMany" => 25 ,
"offset" => 0
);

```
