United Airlines is shaking things up for summer travelers! Starting June 3, you’ll need to check in at least 45 minutes before your domestic flight—up from the old 30-minute rule. Miss that window? You’re not getting on the plane. International check-in times stay the same, but United’s reminding everyone to get to the airport extra early, especially during busy times. Don’t get caught off guard! #TravelTips #UnitedAirlines #AirportHacks #Travel
