Forgotten to check-in online before leaving home for the airport?
With the Aer Lingus app, you can do it on the way with your iPhone or iPad.
Your boarding pass is then delivered to your device, which you simply scan at departures without having to print it.
You can also choose seats and monitor flight delays with the free app.
The service is available on all UK and European routes from Dublin and Shannon, but not yet from Cork (apart from Brussels), or on flights to the US.
Make sure you take a screen grab of your boarding pass and save it to your photo library, in case your signal drops when you're away -- and to avoid pricey roaming charges.
