I believe this was the description of the "Clear Slies Ahead" bonus as per the Bonus Miles Thread (even though there it's called Jan 22-30 Booking Bonus - same thing though, right?):

#2345 - Jan 22-30 Booking Bonus (EXP 01/30/05) Members will earn 40,000 bonus miles for roundtrip travel in Envoy Class to Europe; 10,000 bonus miles for roundtrip travel in any class of service to the Caribbean or Latin America; and double miles on everything else for roundtrip travel between now and December 31, 2005. To qualify, a one-time registration is required prior to your first departure. Bonus miles earned only for tickets purchased and bonus registrations between January 22, 2005 and January 30, 2005 for travel on US Airways, US Airways Shuttle or US Airways Express between January 22, 2005 and December 31, 2005. Members will earn: 40,000 bonus miles for the purchase of paid fares for roundtrip travel in Envoy Class; 10,000 bonus miles for the purchase of any paid fare for roundtrip travel to/from Bermuda, the Caribbean or Latin America; and will earn double miles for purchases of paid fares for roundtrip travel within the U.S. or Canada and for paid Coach class fares for roundtrip travel between the U.S. and Europe.

I have booked and flown a number of flights after registering, but no bonus miles yet. Please share your experiences, thanks!
