We use American Express for our travel at work (it is required). As a 1K on United, I get upgraded about half the time. In the last few months, I started getting emails from Amex showing that my flight had changed. An upgrade is considered an flight change and notification is sent to me and my employer. While I understand the need for them to be notified if I change my flights (as I do often on return flights), the upgrade notice serves no purpose. Wondering if anyone else also get notification to their employer about upgrade/flight changes.
