Similar experiments with the gold line last night. Driving down to EDI for the last flight of the night but got caught in a bit of a blizzard on the A9, snow gates closed. Phoned up and explained but most they would do was a new booking for the next day plus a £35 change fee. In the end turned around found a proper mobile signal and booked new flight online for £17.50 and a few avios.
At least Avis and Heathrow parking were amendable to my weather delay and no extra charges for hire car or Heathrow parking.
