Looking for some help on choosing between 7A or 9A. These, along with 11 are the only true window seats left for an upcoming flight from GRU to ORD.

No interest in 11. In fact, I typically avoid the 2nd J cabin to not have to deal with all the boarding that goes past you and also the risk of maybe a baby in the front row of PE/Y.

However, I recall the footwell is substantially larger on Polaris bulkhead and was wondering if anyone has sat in 9 and how it was? One thing that worries me is do the FA's use the area in front of you to put snack baskets? Just not sure I would want to be in that row if that counter in front is used for that. Also, how is the noise from the galley? 7 would be somewhat close to the galley but not as close of 9 of course. I like that there is no lav on the A side mid cabin or I think I'd be choosing 7 for sure.

Thanks.
