I just got upgraded on an SFO-HKG flight. I have flown Polaris twice, both in 1A. I am short so do not really need the bulkhead but like it since prefer being in the first or last row of a cabin. 1A is taken but I am now holding 9A. The only odd row seats in the mini-cabin are in 5 and 7. I know 7 is not great. The whole second cabin is open. Are there any drawbacks to 5? Thinking I should leave 9A for a taller person. Thanks!
