My father left his iPad on a Ryanair flight last year and realised after we checked into our hotel. We both agreed that it was pointless to even check up on it (because it is Ryanair!). He did send an email to ask about it, which was unanswered.
Lo and behold, the iPad pitched up at our house in England (unannounced) 2 weeks later! They mailed it back to us without even asking!
Very surprised and pleased at their service.
... If Ryanair can do it I don't see why EK can't.
