Another SW credit question

[NC State]

I purchased tickets on 3/30/11, I have received some lower rates so I have some credit built up. In order to use the credit do I need to fly before 3/30/12 or book before 3/30/12 (thinking of an April trip)?

Unfortunately, you need to complete the travel by the expiration date.

I thought so. Thank you for responding.
