Recently booked package holiday through co-op travel agent to Malaga. They used Fleix trip, when I asked do i need add API details to Monarch website, they said no need to input ,if we book for package holiday through travel agent, is it true? The staff quite helpful go to Monarch website to check is it able to input the API details although we have a booking reference but without the email address(explain this is fleix trip email for the booking, they don't know) so we can't do it online. She also go to flex trip to check, the website said easyjet and thomas cook airline need input API online but not mentioned Monarch.
Just worry in case airline reject because we have not add API details. Please advise.
