Shockingly bad, I used travel trolley because when I searched for my flight it was about £30 cheaper than direct with the airline. What a mistake that was! Their customer service is up there as one of the worst I have ever encountered. They got my name wrong and when I called them they said it was fine even though I was telling them I couldn't check in online. Got to the airport and had to spend ages queuing to get it changed, luckily the airline waved the fee Then my flight got cancelled on the way home and they took 5 days to let me know so when I tried to re-book I couldn't get a direct flight home which is what I paid almost.double for cause I don't like flying and didn't want to transfer. When I emailed customer service they said it's not their problem. It clearly was, had they told me straight away when the flight for cancelled I could have got a direct flight. Cost me more than that £30 saving at the start... If you can, I'd recommend avoiding.
