Don't know if you've seen this, but it looks like a good deal:

(Reported on MSN at http://expedia.msn.com/daily/travnew...99twabonus.asp )

Fly business class on any Trans World Airlines flight this summer and you'll receive a bonus of 15,000 frequent flyer miles. Fly first class or full-fare coach and you'll get double miles.

The double miles offer is good on travel through 25 August, while the offer of 15,000 bonus miles is valid on travel through 15 September.

Both offers are good for travel on any TWA flight except for those going to or departing from the Middle East. Although offers are not valid on flights on TWA's partner carriers, the double-miles promotion is valid on flights aboard Trans World Express, TWA's regional branch.

Once passengers purchase a ticket, they must register on or before 31 July; to do so, call 1 (800) 325-4815 and follow the automated instructions. The promotional code for the double miles offer is 87382, and the code for the Trans World One bonus miles offer is 89663.
