if you know someone on the ground who has access to the P/ and S/ (confirmed and standby) list and can give you a hard printout or email it to you can be a great tool when you check in for staff travel. just make sure you place it on the counter where they can read it. they become very nervous but also ensures no person jumps the queue. the last time when i did this the check in staff asked me where i got the list from. i replied "same place as you do". yep, no drama getting my upgrade and in the right sequence.
