Received an email today from MCI stating:

"The partnership between MCI and United Mileage Plus is being
discontinued. As an existing MCI customer /United Mileage Plus member,
this change will not affect your current MCI service or rates. You will
continue to receive Mileage Plus miles through February 28, 2003.
The United Mileage Plus miles you have accumulated to date, as well
as any miles you earn between now and February 28, 2003, will be posted
to your United Mileage Plus account."
