@Gary **************
the real questions are
have you done at least one 90 day report in person or by mail to get into the data base?
are you trying to use the system from 15 days before down until 7 days BEFORE your due date?
do you get the error message or does it just not go past page one
If those answers are yes, then definitely try to leave out the flight number and see if it will click over to page two.
If you keep getting the error message you can't use the online system.
