Have been attempting to use OLCI since yesterday at 15:00 EDT for series of flights, first of which departs today at same time. Leg 1 is YOW-YYZ AC457.

OLCI accepts my info and finds me in system. On second screen, I select myself to checkin and attempt to continue. Third screen is an error msg stating OLCI not available now.

I've never experienced this before. Is it the system or just my reservation?
