概念：

空の結果配列を作成します。指定されたデータをループします。すべての項目について、結果配列に存在しない場合はプッシュします。存在する場合は、アイテムtitleをそのfield_airline要素の結果配列にプッシュします。

コード：

$array_result = array();

if ( ! empty($array)){
    foreach($array as $item){
        // item already exists in results
        if (isset($array_result[$item['field_airline']])){
            // prepare title
            $title = $array_result[$item['field_airline']]['title'];
            $title[] = $item['title']; // push into existing array
            // replace array of titles
            $array_result[$item['field_airline']]['title'] = $title;
        }
        // encountering for first time
        else{
            $array_result[$item['field_airline']] = array(
                'field_airline' => $item['field_airline'],
                'title' => array($item['title']),
                'field_route_location' => $item['field_route_location'],
                'field_time' => $item['field_time'],
            );          
        }
    }
}

$array_result = array_values($array_result); // reset the keys in results
