Short answer: no. Not by phone, not in the app, not on any tracker.
There is no such option on any airline site. Agents cannot confirm whether a named person is booked.
Seat maps show status only. Blocked seats are often held for crew, with no passenger attached at all.
Status, gate, delays and landing time are all public. That answers the real question.
That six-character code opens your booking and your co-travellers' details. Cover it before you post.
