As far as EUA, DuhWane, what is that really mean A4 F4 and there are 3 seats left on ITN.com seat map? </font>
CO generally reserves the bulkhead aisle on the left-hand side for passengers needing assistance, and won't assign it until check-in. As such, it shows up as booked on the seating chart. So, the 3 seats you see + the 1 blocked seat = voila!
