error location screenshot

the number of values in tripoption change in each request.

there logic problem in code tripoption example outputs 2 values.. loop keeps going , says array out of index.. have no idea how fix issue. 

 var arrayofflights : [flightdatamodel] = [flightdatamodel]()          if json != nil {              //insert airline data arrayofflights             if let myjson = json as? [string:anyobject] {                 if let trips = myjson["trips"] as? [string:anyobject] {                     if let data = trips["data"] as? [string:anyobject] {                          if let carriers = data["carrier"] as? [[string:string]] {                             (index, carriername) in enumerate(carriers) {                                  var myflight = flightdatamodel(airline: carriername["name"] string!, price:nil)                                 self.arrayofflights.append(myflight)                                  println("\(self.arrayofflights[index].airline!)")                              }                         }                     }                      if var tripoptions = trips["tripoption"] as? [[string:string]] {                          (index, tripoption) in enumerate(tripoptions) {                              self.arrayofflights[index].price = tripoption["saletotal"] string!                            println("price \(self.arrayofflights[index].price!)")                          }                      }                 }             }

parameteers in url jsjon request:

var parameters = [     "request": [         "slice": [             [                 "origin": from,                 "destination": to,                 "date": when             ]         ],          "passengers": [             "adultcount": 1,             "infantinlapcount": 0,             "infantinseatcount": 0,             "childcount": 0,             "seniorcount": 0         ],          "solutions": 5,         "refundable": false      ] ]

the error because trying access element in arrayofflights index greater size - 1.
