I'm w/ flowerchild...I have a bump voucher as well and yes, although TWA will be run by AA they will still be different flight numbers and considerd TWA...I think it is going to be considerd TWA and American Airlines Company...anyway if a TWA destination goes away I think they'll honor it on AA otherwise no...is the cert good for Hawaii? I found some places in the carb. I could go to get the most out of my bump...we will see
