Looking at upgrade chance for 10/3/2022 UA214 HNL-SFO. Flight status shows the plane is a B737-800SFP that will fly into HNL from LAX, but the seat map shows only one exit row in Y and a F cabin that does not have 1AB and 2AB. F is full. The total number of seats look smaller than a 737-800, with last row in Y being 34 rather than 38. Can one expect the missing 1AB and 2AB to appear later that might be available for upgrades? Or is this really a 737-700?
