Something weird happening when booking seats on Asiana's website. We are a family of 3 and our 3yr old son is allergic to peanut.
No matter where we book 3 seats in the middle row, the aisle seat (the only free seat in the row) always appeared occupied. I've changed the seats 3 times now to a middle row that's completely available, even the last row on the plane.
This seems weird to me because I don't believe there has been someone actually selecting his seat at exactly the same time on different occasions + there are other seats available.

Would this be because of the peanut allergy and they have made the seat unavailable till the last minute?
Anyone had this happened before?
