I did OLCI Saturday for a Sunday flight, about 22 hours out. The flight was showing P1F1. Answered Yes to the "do you want to upgrade" question, but did not get it, so I aborted check in. Tried again Sunday about seven hours out and this time got the upgrade.

I did not think to look at my reservation to see if EUA had moved me before the second OLCI, or if it happend when I hit the Yes button.

I recall a previous trip where I did look at my reservation after an aborted OLCI. My seat assignment was gone (lost exit row ) so I clicked through to change my seat and up popped a map of the F cabin . In this case the computer moved me sometime between the aborted OLCI and my look the next day.
