Transfer of data from flat file

hello

I am trying to create a package. I am executing the query select * from db; in the sql query and sending the result to test.

While using the flat file connection manager , I pick up the particular flat file and change the column names etc...It throughs me an error:

The last row in the sample data is incomplete.the column or row delimiter may be missing or the text is qualified incorretly.

A sample of how my data is in the flat file is:

Flight_id Flight_Number Starting_From Destination
--------- ----------------- ----------------- ------------
1 101 CH LA
2 102 CH OAK
3 103 SF TX

Is there any wrong with the data in the flat file.or do i need to get the data from the database to the flat file in a different way.

Thanks
