I booked a flight through Opodo for Ryanair, bad combination anyways. In my case, the online check-in did not work, neither through Opodo site or app, nor through Ryanair. The reservation number for my flight could not be found on Ryanair, I couldn't reach any custom service, paying 55 Euros extra, although I could prove everything with shot screens. I feel ignored and not taken serious with the problem Opodo made for me. It IS a scam. Trying to reach any service mail, but now my mails ‚can not be delivered' for some reasons. Don't use Opodo.
