Just earned a VDB voucher from AirTran last week, but they pull out of ROC (my home city) in April, replaced by Southwest. Since the voucher won't expire until December 2013 and AirTran operations will be replaced by Southwest, I was curious if anyone had success in having Southwest honor these in a similar situation.
I'm not sure I'll be able to use it before April, but I know I'll be able to use it, should Southwest allow me, before it expires.
Thanks!
