Changing your seat on Copa Airlines in 2026 can be done through three primary channels: the website, the mobile app, or at the airport. The most efficient way is to go to the "Manage your booking" section on Copa.com. You will need your reservation code (six characters) and your last name to access the flight details. Once logged in, you can select "Seats" to view the interactive seat map. If you are within 24 hours of your flight, you can also change your seat during the Web Check-In process. Keep in mind that while standard seat changes are often free, moving to "Economy Extra" (which offers more legroom and closer proximity to the exit) will require an additional fee or the use of ConnectMiles. If you have elite status with ConnectMiles or Star Alliance, you may be eligible for complimentary upgrades to better seats. If the online system is locked, you can still request a seat change at the airport kiosk or with a gate agent, though availability will be much more limited at that late stage of the journey.
