For my SFO-SYD roundtrip this December in the new config 747, .bomb seatmap showed RHS C and the front of E+ blocked, which is normal as far as I know. A few days ago, everything became unblocked. Now, C is still unblocked but the middle of E+ and the front of E (rows 33-43) is blocked. As in the new config row 44 is missing and in the old config rows 35-44 is E+, could this be UA’s new way to simplify substitutions of the new config metal by the old one?
