The headache alone would entice me to pay it.....
And that is why they do it!
You can almost guarantee the moment this charge is challenged, they will waive it 'in good faith'
It needs to be challenged properly in a court of law, so that other people who have decided the headache was too much may be re-imbursed.
In my prior post on this, I was trying to infer that the person writing the invoices considered airborne only transit incurred the charge as well as groundbased transit.
This person is either trying to make bonus, or has an ill-concieved view that airborne or ground based, a transit charge applies.
