I am scheduled to take a trip next week for work that is booked entirely through Continental, but two of the legs of the trip are actually on Asiana, codeshared on Continental. I can select my seats on the Continental website for the Continental legs, but can not find a way to get Asiana to let me do it on the Continental site or on their own site. Does anyone know of any tricks that I might have to use in order to get to select my own seat for these (much longer) legs of the trip?
