Is the number 33 being nixed on newer and refurbished aircraft and what’s wrong with this number? I can’t find any culture that believes it to be unlucky.
Usually the answer is to enforce some kind of number-to-airplane-landmark consistency, such as making rows 20/21 exits on narrowbodies, and then skipping rows 16, 17, etc. as a result. I'm not quite sure what the scheme is for skipping row 33.on those planes. However, note that the widebodies do have row 33, so I don't think it's a cultural avoidance.
I'm also now curious if someone has the explanation!
