Registered for bonus 2345 (travel to the caribbean and receive 10,000 bonus miles). Trip had to be booked within a certain time frame in Jan. Took the trip in June and never received bonus that I registered for. Contacted USAir and was told "Bonus takes 6-8 weeks to post". It will be 8 weeks tomorrow. I guess they'll be hearing from me again and I have a feeling I'll be fighting for these miles.
