A few weeks ago I flew MSP-SEA as part of a trip and the lady sitting next to me in FC had bought the e-upgrade when she started her trip in North Carolina. What's amazing is that there were a ton of elites in the back of the bus on the MSP-SEA leg (wait list maxed out at 24), yet she was able to pay $100 to upgrade trans-con. Something wrong with this picture in my opinion.
Btw..she said she was on a super cheap fare.
