S. W. LUV voucher credit

[yankebabie]

Booked a flight with a $100 LUV voucher and $205 on credit card. May have to cancel flight. Will I lose the credit from my LUV voucher or will the $100 from the LUV voucher and the $205 I paid out of pocket go on the same credit and if so will the expiration date on the credit be the same as what was on my LUV voucher, which was 9/12. or will it change as it will now be a credit? thanks for any help.
