United Airlines Tightens Domestic Flight Check-in Policy | JQJO

United Airlines is implementing a 45-minute check-in cutoff for most domestic flights starting June 3rd, regardless of baggage. This change, mirroring policies of other airlines, aims for greater consistency. Most major US carriers offer online check-in 24 hours in advance. While check-in times vary across airlines and locations (e.g., Delta's 30-minute domestic cutoff for carry-on only passengers, American's 45-minute cutoff for domestic flights, Southwest's 45-minute baggage cutoff), the trend is towards earlier check-in deadlines to improve on-time departures.
