You are right, but the cause of returning more than single scalar was a typo, so its fixed now.

(BTW: Is the latter behavior really intended?) Do you mean $count++ ?

If so, I need the previous value of @data, so if you can tell me a better solution I'll use it.

Because if I try the code as 

               if ( grep( /^$airline/, @data) )
                {
                       return $data[-2];
                }

it returns wrong value if there are additional notes in the definition file
