49,000 miles with United, gone, without notice. I've spent hours on the phone, but complaints fall on deaf ears. While, on hold, an offer to start a credit card and receive 20,000 miles. Certainly, I will not take that offer, to only build up miles again, for them to wipe them out, without care. I was sick for 2 years. Now that I feel better, I and a friend will go to Hawaii, but not on United Airlines. Wonder how their policies are encouraging business?
