"I had to change the day of my return journey from LHR part way through my trip abroad. I did this through a short call and follow up email to the helpline. I received notification that the change had been made giving great confidence. On the day of my return journey my fight was severely delayed. Again, I used email to inform TaxiCode. My driver had been at the brunt end of all the changes but was courteous and drove with due care. Everything worked perfectly and I will certainly use TaxiCode again."
