A terrible customer experience. I would recommend you to avoid this company and buy flights directly from the airline. Opodo is not familiar with airline policies but they accept payments for seat reservations and all kinds of extras. When airlines later enforce their rules, Opodo says they are not responsible for airline rules and will not refund any payments they incorrectly accepted or charged for. It's virtually impossible to get through to their customer service centre and when you do, you will be passed from pillar to post. They do not care about their customers once they sold the ticket. If everything goes smoothly, it's probably ok but it will turn into a nightmare if anything goes wrong. Nobody will take any ownership for anything and you will be left on your own to deal with any issues.
