Ease of Getting Upgrade to BE from Y Class Using Miles
Hi,
I am thinking about transferring some miles from my AMEX account to Delta to take advantage of a bonus mile offer I got in the mail. Before doing this, I want to know how easy it is to get an upgrade to BE from a full fare economy ticket (20,000 miles RT). I'd probably use the ticket next March or next summer and would go to either Germany, Greece or Italy.
Thanks for any answers!
