check the below to get fare and route data

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope) {
  $scope.name = [{
   "flightsDepartur":[
        {
          "fare":"9,000",
          "route":[
            {
              "source":"Delhi",
            }
             ],
         },
     ]
  }];
  angular.forEach($scope.name, function(k,v) {
        angular.forEach(k, function(k,v) {
       console.log(k[0].fare);
       console.log(k[0].route[0].source)
    });
    });
});

The problem is you are assigning values to $scope.allData inside a promise. since the javascript asynchronous before the data being assign to $scope.allData for each loop start to execute. at that time $scope.allData was undefined. so it produces an error.

create a function and call that inside the promise to prevent the error

$http.get('data.json').then(function(response) {
      $scope.allData = response.data;
      callLoop()
 },function(dataStatus){
      console.log(dataStatus);
 });

function callLoop(){
    angular.forEach($scope.allData, function(flidata) {
        angular.forEach(flidata.flightsDepartur, function(flidatIn) {
            console.log(flidatIn.fare);
        });
    });
}

Try change

angular.forEach(flidata[0].flightsDepartur, function(flidatIn) {..

to

angular.forEach(flidata.flightsDepartur, function(flidatIn) {..

and when using then function to get response change to this.

 $http.get('data.json').then(function(response) {
        $scope.allData = response.data;
     },function(dataStatus){
         console.log(dataStatus);
     });

Demo

var app = angular.module('anApp', []);
app.controller('ctrl', function($scope) {
  $scope.allData = [{
    "flightsDepartur": [{
      "fare": "9,000",
      "route": [{
        "source": "Delhi",
      }],
    }, ]
  }]

  angular.forEach($scope.allData, function(flidata) {
    angular.forEach(flidata.flightsDepartur, function(flidatIn) {
      console.log(flidatIn.fare);
      console.log(flidatIn.route[0].source);
    });
  });
})

<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.5.0/angular.min.js"></script>

<div ng-app="anApp" ng-controller="ctrl">

</div>

I am using this but not getting anything angular.forEach($scope.allData, function(flidata) { //console.log(flidata); angular.forEach(flidata.flightsDepartur, function(flidatIn) { console.log(flidatIn); }); });
