Fees, Fees and email spam. Better booking direct
They don't really attempt to make their fees stand out. Cancellation for flights £25pp each way. Non refundable flights are not clearly labelled - watch out for these. Also just because I booked a flight with you doesn't mean I want to be inundated by your spammy emails. Next time I'd rather pay a little more and book direct with the airline. First time user and I would NOT use again.
