An odd thing at TSA pre✅ this AM at the Spokane Airport. The lady in front of me in the pre check line had a boarding pass on her phone. When the TSA guy put her passport in the reader he said she needed a paper boarding pass and had to go back to the Delta check in desk. I had been able to check in online for my full trip to Amsterdam yesterday including downloading boarding passes. I only stopped at the desk because it wasn’t busy and I knew they’d have to verify my passport either there or at the gate. At that time the desk agent offered me a paper pass and I almost refused because I’m trying to go all digital this trip but decided WTH…and took it. Glad I did! TSA guy said sometimes the machine does not take a digital boarding pass with a passport. Very weird.
This may not happen anywhere else but just wanted to put my experience out there as the travel season ramps up!!
