So this is landside staff who have jobs in multiple terminals. Seems
like a small subset, being that far away from anything airside (and
most airlines only have check-in staff in one terminal).

Not everyone works for an airline.

Sure; there's all the landside shops and their supply chain. But are
they hopping around on the tube during working hours?

Furthermore, some airlines use handling agents whose staff work in
multiple terminals.

Those are the ones I expect the employers to lay on special transport
for.

Then add in cargo staff who may need to move from the Cargo terminal.
Commuting staff getting from car parks to places of work.

On the tube? Hatton Cross isn't in the free area.
