Just noticed that UA assigned me 19A on a new configuration international 777. Not sure what exactly they are planning to do -- maybe provide a folding chair for me? I think what's happening here is that they are in the process of switching out the new-config 777 with the old config. They reassigned me a new seat (not sure why, but I am glad I am not in 24D anymore). Unfortunately I cannot pick a new seat online yet -- would prefer aisle (20B) over 19A.
