TWA does this call back every month to renew and it drives me crazy! I'm not quite that much of a FF afficianado to keep doing this for a year and sadly I can't program the computer to do it! It can wear you out since you must call on that day to extend it! I finally caved on my recent attempt to book 3 for Puerto Rico and just decided to use the mileage for California! I assumed they do not to this to their elite level flyers. Obviously, I've got no status here- not since the flight attendants struck in '96!
