I have not flown on Delta since 1999.

While trying to clear my enormous email inbox, I noticed that there were a lot of emails from Delta on a monthly or even weekly basis, but they all were inside my spam folder.

What I had not realized was that my Delta Skymiles account had a balance of 112,600 miles as of yesterday. (!!!) I didn't even know what my password was... but I was able to reset it and log in... sure enough, 112,600 miles. I thought it was an error as I couldn't possible forgotten about 112,600 miles, right? So I called Delta and asked. The agent verified it. Their record only had my home address from 1999(2 houses ago), so I updated that as well.

how far can I travel with those miles?(originating in NYC)
