Tips for Flying > Buy tickets

Check the cancellation policy: Usually, if you choose the lowest fare you will not be allowed to freely modify you flight details later on (change dates or passenger names, etc). If you think that you might need to do this, you should consider buying a more flexible (but also more expensive) ticket.
