I know FTers don't sit in the back of the bus, but I have no status on AS since they split from the AA family. But I don't want to board in the last group and have to check my smallish bag which has too much of value. I believe the next-to-last group to board is still the "back half of the plane" but does anyone know at about what row that starts, on a 737-800? I sort of recall hearing 20 and higher last time I heard an announcement based on actual seat rows? Thanks much in advance!
