I have a trip planned for FAI-SEA-DCA-PDX-ANC-FAI next month. On the SEA-DCA leg I'm way in the back of the bus, so set a seat alert with TripIt for something forward of the wing, aisle or window. And today I got a notification that something had opened up, 13D.

BUT when I go to my reservation on AlaskaAir.com, the seat map is missing rows 12 to 14 for that flight. IOW, goes from 11 right to 15. So I can't grab that seat??? The FAI-SEA flight is the same thing. DCA-PDX has row 12, but not 13 or 14. PDX-ANC has all the rows! And ANC-FAI has them too (but that's a Q400, so a different map).

What's up with that? Is this something that I've just never noticed? I looked at the SeatGuru.com maps, some configurations are missing the rows, others are not. Maybe I just fly in row 7 too often....

And if the planes don't include those rows, why? I guess I can understand leaving out 13 (not that I agree with it, if that's the case), but the others?

Thanks!
Don
