My husband and I are flying IAD-CDG on UA915, 787-8 version 2. According to seatguru, seats 6A and 6L in Polaris Business class are "open suites" located at the bulkhead and therefore have "wider footwells". If they are suites (pods?), aren't they just self-contained units that are installed in place? Do the footwells really vary based on location at the bulkhead? Thank you!!
