                HttpContent httpContent = new ObjectContent<FlightQueryRequest>(ReqDTO, jsonFormatter);
                var url = RequestUrl + "/QueryFlight";
                var httpClient = new HttpClient(new RequestHandler() { InnerHandler = new HttpClientHandler() });
                httpClient.Timeout = TimeSpan.FromMinutes(3);
                var responseJson = httpClient.PostAsync(url, httpContent).Result;
