Answer 1

please do like this

$query->select('f.flight_child_id,f.flight_name,f.flight_code,f.flight_dep_date,f.flight_ari_date,f.flight_dep_time,f.flight_ari_time,f.flight_dep_city,f.flight_ari_city,f.flight_child_id');
        $query->from('#__fairinfo as f');                

In view

<?php foreach($this->items as $i => $value):
?>
    <tr class="row<?php echo $i % 2; ?>">
        <td>
            <?php echo $value->flight_child_id; ?>
        </td>
        <td>
            <?php echo JHtml::_('grid.id', $i, $value->flight_child_id); ?>
        </td>
        <td><?php echo $value->flight_name; ?></td> 
            <td><?php echo $value->flight_code; ?></td>
            <td><?php echo $value->flight_dep_date; ?></td>
            <td><?php echo $value->flight_ari_date; ?></td>
            <td><?php echo $value->flight_dep_time; ?></td>
            <td><?php echo $value->flight_ari_time; ?></td>
            <td><?php echo $value->flight_dep_city; ?></td>
           <td><?php echo $value->flight_ari_city; ?></td>
           <td><?php 
                $model = $this->getmodel('Your model name');
                echo nl2br($model->functionname($value->flight_child_id));
            ?></td>
         </tr>
<?php endforeach; ?>

Model function

functionname($id) {
        $db     = JFactory::getDBO();
        $query->select('d.flight_id,d.fair_type,d.fair');
        $query->from('#__faredescription as d');
        $query->where('d.flight_id ='.$id);
        $db->setQuery( $query );
        $rows    = $db->loadObjectList();
        foreach($rows as $row) {
            $rowss[] = $row->fair_type.','.$row->fair;
        }
        $row    = implode("\n", $rowss);
            return $row;
 }
