Now you can just select the seat from the seat map in any upgraded cabin, and DL.com will price the difference for you and you can confirm it, using $ or miles.
Never had an issue.
The times I've upfared, DL has never charged me the $50 to take over the ticket, just the cost difference between the corporate Y rate and the new fare.
The only time they've charged me is when I go through them to change flights during non-IRROPs situations instead of going through AMEX GBT (and I only do that in rare circumstances where I need to change something on the spot and don't have time to deal with AMEX getting in the middle).
