I work for British Airways and I currently fly Boeing 747 aircraft. When
the aircraft are presented for each flight, there are no undercarriage
pins fitted as routine, apart from the nose gear steering bypass pin.

As far as I am aware, the only time we fit the pins is when guys have to
carry out maintenance in the wheel well area, or on the gear itself.
That would make a lot more sense than throwing them away.
