The "45-minute rule" at airports generally means passengers must complete all check-in procedures, including dropping off any checked baggage, at least 45 minutes before their domestic flight's scheduled departure, a policy strictly enforced by airlines like United and Delta to ensure timely boarding. While you might check in online earlier, the 45-minute mark is the hard cutoff for bag drop, and missing it risks denied boarding, even with a boarding pass. International flights typically require even earlier check-ins (60-90 mins) due to customs and security.
