This is a bug/missing feature that happened after applying the new technical patch on the existing servers.
Before, after you went into Flight Number -> Scheduling, under assigned aircraft (e.g. AA-12345N) you could click that link and be brought directly to the schedule page of that aircraft (it's the "Currently assigned aircraft" area).
Before the aircraft registration number was coded with URL link, now it is not and it's just a plain text.
Can we please get that URL linking back?
Thank you.
