KLM is now going to do a “test” at Schiphol on european flights to board 737 also from the back..
That'll be interesting on a rainy windy day as they decide NOT to use the finger. Given that KLM has allocated seating what difference does it make? In days of yore, when boarding via a finger, it was done rear rows first, then mid section etc.
They already do this at various outstations. MAN is one where they board through the Airbridge and the bag steps similar to how BA do it at MAN. Turnarounds are approx 10-15mins quicker.
