Since Air China is part of the Star Alliance with United Airlines, can I use my Mileage Plus to upgrade to Business Class?
No, as of now they do not honor that for this low-priced tour package. You need to check with them directly to reaffirm this since agreements change without notice, and also to determine the latest information on what is required by United to show proof of your flight in both directions if they resume honoring this. They had been requiring that you retain your boarding passes, among other pieces of evidence.
