I noticed that our booking with Travel Trolley was incorrect and, before going to amend it, read the below reviews and felt very nervous. Unfortunately they were as bad as you all say, ridiculous levies - for amending a flight with a difference of £75 on sky scanner they would charge £710 - £400 to make the change, and then the extra in flight costs as they say they can’t give us the ‘new customer’ price anymore and need to give us a new made up price for people amending flights. Will always book with the actual carrier in the future!! I’m going to complain to Skyscanner as it was them that sent us to these cowboys.
