No mobile check-in for international travelers
First airline I am traveling on that doesnt accept a non-U.S. passport for mobile check-in, when LEAVING the U.S. This happens repeatedly. United has of course outsourced the document check and that company cant process international travelers - which isnt really surprising for a provincial airline. United, thank the tax payer for bailing you out. Its not because of your level of service that you are still in business.
