I had my first experience today flying on a ticket booked through my company's travel agent since UA removed access to secure flight data on the website. Before booking the ticket in Concur I made sure to add my full middle name and my known traveler number to my profile in Concur.. and everything worked perfectly.. was able to scan my barcode in advance to confirm my 3 and used the PreCheck lane at SEA this morning. Sitting at the Lufthansa lounge at IAD right now..I haven't been here (or to IAD) in over a year.. I've forgotten how much I like this lounge..
