TW miles transfer to HH program in the 1:2 ratio. 5,000 TW miles equals 10,000 HH points. I think it is a pretty nice conversion personally cause 50,000 TW miles earns 6 free nights at an upscale Hilton property or other awards of high value. You may consider buying a ticket to get to a TWA gateway and taking a few transatlantic trips to burn a few miles.
