It's a great app and I've used it for…

It's a great app and I've used it for years. My recent experiences was a fast refund on a booked return journey to Gatwick at the end of Dec. Trainline refunded me no questions asked and speedily, whereas the Airline, mentioning know names but Easy to remember, no refund and a £50 charge to change the date. Reason for changing plans was due to a consultant Heart specialist who's appointment I'd been waiting months to get. Simple to use and the only negative comment is occasionally I look for a fare but don't buy a ticket and hence starts the repetitive emails saying Do you still want to make this journey or you've left something in your basket. Annoying bbut otherwise I'd givev 5 stars.
