Looking at a LHR flight in the high J config.

https://www.united.com/ual/en/us/fly...767-300er.html

According to the official site it says that only the low J config has a fixed bassinet at 1F but the high J config does not have one in polaris. The wiki has a question mark on this. Does anyone have any experience with this?

We’re considering a flight with a 5 month old.

Thanks!
