I just got off the phone with elite reservations trying to book a late October trip MSP to LGW. When I asked the agent to check on the cost of fares eligible to upgrade, she fiddled around for a few minutes with no luck and then said, "Well, only full coach fairs can upgrade." She was unwilling to quote an accurate fare saying, "Well, it would be around $4,000." She was unwilling to check alternative routing through DTW or AMS
saying, "Well, it would be the same price." I am really wondering how I am going to be able to use the more than 200,000 miles that I have banked. Domestic upgrades have been great as gold elite (soon to be platinum after my China trip), but it seems virtually impossible to upgrade internationally anymore. Is CO any better about international upgrades from other than full coach fares? What are my chances of upgrading on CO transatlantic with NW miles?
