I remember seeing once a flight home that involved me flying on the RJ 342 to DTW from YUL. I was so ridiculously tempted, but had no money.
I got to try one of DL's refurbished 767s in April when I went to ATL for an MRO exhibition. The plane was a lot of fun as well as Atlanta and the exhibit hall (though I felt incredibly out of place, being only a student and all). Plane was coming into DTW from GRU by the way.
