I've faced this problem twice now: after selecting my seats ahead of time, I was assigned to much less desirable seats as soon as online check-in began. It appears that the company doesn't respect seat selections unless you're a premium customer. On my second trip with family, we were separated and placed in different seats. They claimed the flight was full and couldn't make any changes, even though there were several exit-row seats available. Those seats were taken by the staff instead. So much for their 'operational reasons.' Now, if I have to fly with this airline, I won't even bother selecting seats—they'll just move you wherever they want. If I'm traveling with family, I will avoid this airline altogether.
