Found the issue, the FAA is sending flightplan data as BOEx but positions as BOE00x... we're working on a fix.
Imho you should show the flights as per the ARCID on the FPL. If the FPL shows BOE001 then that's what it should show here instead of you removing digits to suit. I know you said that it's for numpty visitors that won't think to include them but that's their problem. I'm sure some message could be put up for when flights searched for are not found, eg. 'BOE1 was not found. If you're sure about the identity, try BOE001' etc. 2 min job.
