Priority Club is offering 25,000 Delta miles for signing up as an Intercontinental Hotels Ambassador Club member through October 31, 2004.
Just as a mileage-earning deal, this is excellent. Ambassador Club costs $150 to join, which means that the 25,000 miles cost 6/10ths of a cent apiece. Plus Ambassador Club gets you Gold status in Priority Club and special benefits at Intercontinental hotels.
The terms and conditions of the offer say that you need to be a Priority Club member (sign up before taking advantage of the offer) and that you have to have selected Delta Air Lines as your preferred earning partner (so set this up also before taking advantage of the offer).
Further, I suspect that the offer was intended for a limited audience, though the website suggests no such restrictions. It’s a good idea to print a copy of the front page of the offer just in case.
