Our equipment was changed to a 737-9 and our seats were moved to 18DEF. Looks like 19-21 are the exit rows. I asked the messaging service about this because I could have sworn I saw that kids couldn't sit in the exit row OR immediately in front or aft. But the agent had never heard of that, and confirmed our child was booked with her 2021 birthday so the system would not have put her there.

Could just be anxiety overdrive given the long flight and state of the world but if anyone could provide some clarity that'd be great. Just trying to avoid a hassle at the gate/after we board and try to sit there if we can't.
