You should determine whether you qualify for the change before using Alaska Airlines change flight(https://cutt.ly/YK68lFl) service. These are the choices you need to be aware of:

Direct contact was established with Alaska to book the flight.
Nobody in your reservation has checked in for the same flight.
The airline ticket isn't part of a mileage programme.
In order to proceed with the booking, you did not make any specific service requests, such as for pet transportation or wheelchair help.

You can make modifications to your tickets and take advantage of flight changes if all of these are followed. Consider a scenario in which you are not permitted to change your flight tickets online. In that scenario, give a call and ask an airline representative to approve the flight change requests over the phone.
