I'm flying to Faro with Aer Lingus in a couple of weeks. Their website says that you can use a boarding pass on your smartphone at most airports within Europe but that Donegal and Faro airports don't accept mobile phone boarding passes.
However, there is no problem with using a Ryanair boarding pass on your smartphone at Faro Airport, which I have done twice already this year. Any idea why Aer Lingus have a problem and does anyone know what they're doing (if anything) to rectify it?
And does the problem apply to both outgoing and incoming flights?
