Passengers who do not follow this new rule will cause them to miss their next domestic flight. One U.S. airline is changing its pre-departure rules. United Airlines changed its check-in time limits for domestic flights. Following the new rules, all travelers on domestic flights must check in at least 45 minutes before departure.
What’s Changing From the Previous Policy?
Usually, the travelers flying within the U.S. without checked bags could check in up to 30 minutes before departure. This flexibility is now gone. According to the new policy, all passengers must follow the same 45-minute check-in deadline.
International Flights Remain Unchanged
Travelers on United’s international flights will still need to check in at least 60 minutes before departure.
What Happens If You Miss the Check-In Window?
The passengers who miss the flight’s check-in deadline will not receive a boarding pass. They will not be allowed to board.
According to United States Airlines: “If you don’t come within your time limits, we will try hard to find another option that best suits your needs. We have the right to deny service, which may result in cancellation of your reservation, denied boarding.”
How & When to Check In?
Check-in opens 24 hours before departure and can be completed through various options. Take a look at some of the following options:
- On the airline’s website
- Through the mobile app
- At a self-service kiosk at the airport
- At the airline’s check-in desk
The process typically takes just a few minutes and ensures a hassle-free experience for the passengers.
Why Early Check-In Is Especially Important in Summer?
Although domestic passengers can check in up to 45 minutes before departure. Checking in earlier is recommended by United Airlines, especially during the busy summer season. Have a look at some of the following benefits of early check-in:
- Better seat selection options
- Improved seating choices for passengers who haven’t pre-selected seats
- A better chance for basic economy passengers to secure a favorable seat
- Reduced risk of being bumped on oversold flights
Airport Arrival Recommendations
Passengers who are planning to check in at the airport should arrive well in advance of departure time. Check out some of the following recommendations given by the TSA:
- Arriving at least two hours early for domestic flights
- Allowing extra time for parking, rental car return, shuttle transport, baggage drop, and security
- Arriving even earlier if you do not have a REAL ID or another acceptable form of identification
Recommended Arrival Time for International Flights
For international travel, arriving at the airport three hours before departure remains the safest rule of thumb to accommodate earlier check-in and boarding procedures.
