$query->from('#__fairinfo as f');
In view
<?php foreach($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
$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;
}

Answer 2

Duplicate value reason : your #__fairinfo table have one row and #__faredescription table have 4 rows,so that only its display duplicate value
Seems your expectation like this
4 G8-334 G8-334 2012-05-22 2012-05-22 11:10:00 13:05:00 MUMBAI (TERMINAL 1B) NEW DELHI (TERMINAL 1D) GoSmart7,566.00 INR
GoFlexi7,829.00 INR
GoBusiness9,718.00 INR
GOPROMO(ROUNDTRIP)7,136.00 INR
GoSpecial Sold out/Not
