Just wondering is there a self check-in booth at Malaga Airport for Aer Lingus. Boarding passes seem to get more expensive (€8) and there are 6 of us. €48 is a lot.
Find out where the local library is. Back in the day we would just go there and "visitors" are allowed up to an hour free internet. They will usually charge about 20 c per sheet if you want something printed, sometimes they don't bother.
