i am having similar issues. and with all the recent lounge access changes, i buy my passes in advance (which skyguide said was ok to do) and have explained that no documentation is given when i actually USE the pass at the lounge. i submit a monthly receipt of my advance purchase and on the form you must submit for reimbursement, i indicate the date that i actually used the pass.

and recently, they have not been reimbursing.

let's not let them do this to us! i have been emailing (with long waits for replies...) to this email address :
[email protected]

here's a phone number :
18552850291

don't give up! or we won't get paid! and please post anything you find out. thanks!
