Singleflyer,
Thanks for the info. So this morning, on a whim, he tried the OLCI again and it let him check in and print boarding passes. Not only that, due to a delay on his SEA-ATL leg, he had already been moved to F on a later flight on his ATL-MSY leg. He's mostly happy. Amazing how used to having those boarding passes when we leave the how we have become.
