When I worked with Lufty, they were trialling a zonal boarding procedure. Windows were in Zone A, Middle seats in Zone B and Aisles were in Zone C.
Reading through this thread I was thinking about the above and then ... there it was. I haven't flown LH for a couple of years but I think they dropped it. I wonder why as it did seem to work and especially as our German friends love order and method it seemed like a good and feasible idea.
I cannot understand why it takes people 5 minutes to sit down nce they've found their seat. But then I also can't understand why everyone in front of me takes 5 minutes to check in and I'm done in 30 seconds.
