Online check in has been a mess today, for travel tomorrow. The android app wouldn't process it. I was able to start the check in on delta.com but it failed out at the 'select bags' page. After that, the app showed my boarding pass with QR code. But the UG list didn't have me or my companion.
Went back to delta.com and the UG list said I had to be manually processed at the gate.
Called the medallion line and the agent was able to get us on the list (13 and 14 for 2 empty, LOL). Still can't add bags (doesn't really save any time at bag drop so who cares, but still, it's glitchy).

I've had this problem when I've had a RUC pending. But no such for this trip. Huh.
