My guess is there is more to this story than your aunt is telling you.
If you're late/miss a flight, in my experience they will generally do their best to accommodate you on a later flight or on a different airline, though there might be a smallish fee involved depending on the fare difference.
For domestic flights, you are supposed to be in the gate area 30 minutes prior to scheduled departure, though as long as you're checked in before then, and in the gate area 10-15 minutes before departure you're generally fine.
For international ones I think it's checked in 60 minutes prior and in the gate area 30 minutes prior.
