This is a new one for me.

I'm flying tomorrow and when I checked in discovered I was in seat 7E. What? I groom my reservations regularly, and as recently as yesterday I was shown as in seat 6F on the Alaska site. Contacted Alaska via Twitter and they said "I see you're in 6F".

Clearly not what my boarding card said, so I forwarded them a screenshot of the boarding card showing 7E.

Response back? "I see it was booked through a travel agency. They put in a request for 6F but it was not available". The travel agency was everyone's favourite: Concur.

Has anyone seen this before? Why would the Alaska site show me as actually being in a seat in the days leading up to check-in time that I'm not actually assigned?
