Recent reports indicate that Airtran will convert vouchers to Southwest but the process takes between 7 and 30 days. The voucher may be unavailable for use during that time. I don't know if any Airtran Vouchers have expiration dates beyond November 1, but as far as I know there has been no announcement of how those may be handled.

If you have an Airtran Voucher that expires after November 1, please let us know.

For all I know Airtran has been issuing LUV vouchers for VDB and other compensation.
