Green Tag gate check bag left on runway @LAX
18 year 1K never experienced this before - flying today LAX- ASE on RJ700
half full flight, on time left bag at door with ground crew, they scanned bag and forgot the most important part PUTTING BAG ON PLANE
I JUSTCONTINUE TO BE AMAZED BY UNITED, HAVE NO CHOICE Homes IN LA AND ASPEN OFFICES IN CHICAGO AND DC
