Regarding the Canary Islands this again is poor research by the media. Passengers are entitled to the right to care. All handling agents are made aware of this. If onward travel is not provided by the airline then passengers are to make their own arrangements, keep all their receipts and send them into Ryanair where the cost endured will be refunded. All of these expenses have to be within reason to the cost of the ticket, ie 3 star not 5 star accommodation if that is needed etc.
I agree it isnt the best option, but it is the option offered by Ryanair. Passengers are never told thats the end of the line in a wrong destination. This is poor communication by the handling agent to passengers of the policy - they should be fully aware of this.
