Changing seats 24 hours before flight
 

1). I'm currently seated in the elite Y section on my flights. If I want to try and get the exit rows 24 hours prior to departure, do I have to do OLCI, or can I just view my reservation and make the change from there?

2). Also, will exit seats be released for my connecting flight, when I do OLCI, or would I have to wait until the 24 hour mark?

You have to change your seats during OLCI - you will no longer be able to change them through viewing your reservation. You will be able to select exit row seats for all segments during the OLCI.
