My daughter, son in law, and 2children on Canadian passports are flying from Dublin to Malaga with Ryanair. Can anyone enlighten me re the process for check in. Thanks
Same as anyone else. Check in online and you will need passport details. Airport does not check passport details, only Ryanair on boarding. You may have to go into a longer queue on arrival on Spain but unlikely to be a problem assuming they don't need visas.
AS non EU citizens they will have to do a visa check at Dublin airport. This is done at a Ryanair Desk on Departures level before they go through security
