I'll book my wife and myself on ET soon for a trip to LUN next year. I noticed that the default seat map for ET575 (ORD-ADD) is the generic four row 787. I want to get seats in of the row 1 pairs of seats for the two of us (either 1A/1C or 1J/1L). The aisle seats of these pairs (1C & 1J) are blocked on the seat map and correspond to the bassinet positions on SeatGuru (making the big assumption that SeatGuru is accurate in this instance). Can these blocked seats be easily assigned in advance via a telephone call, or a message on social media?
TIA
