Just checked my seat assignments and we have the new configuration! As Itrade mentioned, seats are not guaranteed except A and H. Mrs CLTAussie remained in 3H and I was moved to 5F. Called the Gold line and was able to move to 2H. Hopefully that still works tonight when I OLCI.
US Philly - I wonder if those open seats are being held for people that have been stranded due to the volcano and they will upgrade some elite pax and fill Y to the brim.
