You don’t ECHO in a variable assignment

 $ca = $query->code_airline;  //no echo here!

Also, I believe you’re doing something wrong in calling $query->code_airline, but you didn’t provide your code so I’m just guessing.

Suggestion: chaining is a nice feature but can be confusing, especially if written as one-liner. First of all, write it in full, you can “compact” your code later if you feel so; keep in mind readability and maintenability also:

$query_tc = $this->db->get_where('ticket_code',array('code'=>$ca));
// $ca is the value assigned above. Make sure you're calling $query->code_airline correctly, as per my suggestion.
$row = $query_tc->row();
echo $row->name;

UPDATE:
you might want to be sure that there are actually any result.

   $query_tc = $this->db->get_where('ticket_code',array('code'=>$ca));
   // $ca is the value assigned above. Make sure you're calling $query->code_airline correctly, as per my suggestion.
   if ($query_tc->num_rows() > 0)
   {
     $row = $query_tc->row();
     echo $row->name;
   }
   else
   {
     //do something else
   }
