I just remembered the bit with " £5 fee to print your boarding card using your own pc, printer, electricity"
A friend of mine is getting divorced. She can't afford a solicitor so she uses one of those websites specialized in divorce, specialized in divorce documents and procedures to be more precise. She pays about £30 per drafted document. The company e-mails her the drafted documents and she sends them to court. Nothing else.
So, because she obviously doesn't know how to write the said documents herself, she pays someone else to do it for her. And all she does is printing them off, using her own pc, printer and electricity.
So with the £5 fee for printing your boarding pass using your own stated above, it's exactly the same thing as my friends' divorce documents. When pax will know how to draft (write) their own boarding pass, then fair enough, the £5 fee is out of order. Until then, i see no other option than to pay the fee and enjoy your holiday/ short break/ business trip
