Laravel 5.2 flash data not working

Here is my routes file:

Route::get('/', ['as' => 'home', 'uses' => function() {
    return view('pages/home');
}]);
Route::get('/companies', ['uses' => 'CompaniesController@index', 'as' => 'companies']);
Route::post('/companies/search', ['uses' => 'CompaniesController@search', 'as' => 'companies.search']);
Route::get('/companies/{symbol}', ['uses' => 'CompaniesController@view', 'as' => 'companies.view']);

Here is my companies controller:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Requests\CompanySearchRequest;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use \SoapClient;
use Session;
use Redirect;

class CompaniesController extends Controller
{
    public function index()
    {
        $client = new SoapClient(config('mannisland.wsdl_url'));

        try {
            $results = $client->getCompanies([
                'username' => '********',
                'password' => '********'
            ]);
        } catch(\Exception $ex) {
            var_dump($ex->faultcode, $ex->faultstring, $ex->faultactor, $ex->detail);
        }

        $companies = [];
        foreach($results as $company) {
            $companies[$company->symbol] = $company->name;
        }

        return view('companies/index')->with('companies', $companies);
    }

    public function search(CompanySearchRequest $request)
    {
        return redirect(route('companies.view', $request->symbol));
    }

    public function view($symbol)
    {
        $client = new SoapClient(config('mannisland.wsdl_url'));

        try {
            $results = $client->getDirectorsBySymbol([
                'username' => '********',
                'password' => '********',
                'symbol' => $symbol
            ]);
        } catch(\Exception $ex) {
            return Redirect::route('companies')->with('message', $ex->faultcode.' '.$ex->faultactor);
        }

        dd($results);

        return view('companies/view')->with('company', $company);
    }
}

In my template I have the following code:

{!! (Session::has('message')) ? '<div class="alert alert-danger"><strong>Error!</strong> '.Session::get('message').'</div>' : '' !!}

As you can see within the view() method if an exception is caught I do a redirect with an error message which I am trying to output in the view. No matter what I try though the message won't appear. What am I doing wrong?
