Watch out for Oversold flights...
If check in agent refuse you to print BP,
Stop whining, just get the next flight's BP and head to original flight's gate,
Ask GA for Standby, and if there's seat, you are good to go.
================================================== ==
If the flight is not over sold, they will usually let you go with it,
but not when flight is packed.
As GA usually doesn't open up no-show seats until last minute window,
if you head to original gate as quick as you can, you may get a seat assignment back with your Elite priority benefit
