If all youre doing is booking, it seems like theyre fine - although for several airlines it seems you can't check in online if you book through flightcatchers, so can't get free seat allocation early, and so will need to pay to have any chance of sitting together.
However, if anything goes wrong, they are a complete disaster. We got back (belatedly) from a trip in March, and are *still* waiting for a refund. Flightcatchers/Polani respond quickly but completely pointlessly, are obstructive, at times incredibly rude, and keep repeating the same nonsense but refusing to evidence it in any way despite the ability (and following a subject access request under the GDPR) a legal obligation to do so. The airline issued the refund voucher months ago, and tell us they respond to refunds via the vouchers within 4 weeks - but flightcatchers, 4 *months* later claim to be getting no response.
Also - worth noting - they are not part of any professional trade bodies (like ABTA) - so there is nobody to escalate to, and that probably also tells you all you need to know about their business model.
Overall, I think we saved £50 booking through flightcatchers - they have currently been in the way, possibly actively holding, almost £1000 of our money for going on half a year. Save yourself time, hassle, money and anger - book direct with the airline.
Update in response to reply: people should not be comforted by Flightcatcher's response, which is disingenuous at best. Firstly, there are plenty of reviews here highlighting the same problem of vastly delayed refunds. Secondly, the airline has confirmed to me in writing its refund processes, while slowed by the chaos of the war in Iran, are still being processed in a 3 week window (it has been 4 months since Flightcatchers have apparently been processing this). Their claim to process data requests in line with the law is simply false - I made a subject access request on July 3rd, and the window for response is 1 calendar month. I have followed up twice since (10th August and today) and have had no acknowledgement or reply to the requests, despite replys to the emails that contained them. I have of course made a formal complaint to the ICO.
Stay away from them - your travel will end up far more expensive, far more stressful and taking endless time to try and remedy their obstructiveness.
