Need some advice. We are in 11H & K on 4 legs, SFO-LAX-NRT-BKK-NRT in old C that frequently get changed to new. What is the best way for me to make sure we are together in A/B or J/K if switched to new? Should I move us up to 8 A/B in the hopes that we'll keep those in the new config, since there is no row 11? Thanks.
