Interesting travel day yesterday, was scheduled to fly INV-LHR-JFK and the INV-LHR flight got delayed 4 hours due to a hit with the baggage loading truck. That delay led to a missed connection and offer to continue my journey on VS the following morning after an overnight stay, which was not ideal. After some imploring with flight connections staff, they managed to put me on LHR-EWR, which had to return to the gate after departure due to yet another suspected contact with a ground services vehicle, leading to an additional delay of 1 hour. My final arrival time in EWR (not JFK as orig. scheduled) was just under 4 hours late (due to a long layover). I am guessing, based on earlier advice, that this would be a valid case for GBP260 the arrival at EWR notwithstanding, and even if BA tries to initially finagle itself out of paying by claiming such contact incidents are "extraordinary" and out of their control?

Would it be reasonable for me to ask BA to also cover the taxi fare from EWR (<US$90) given that I saved them the Duty of Care expenses associated with putting me up for the night at a Heathrow hotel, transit, meals and continuing travel on VS?
