I did wonder if DAA had nobbled the facility to gain some extra euros, and said I’d investigate.
Well, this morning I was flying out again and found that I could log on without difficulty. So that previous experience was just a glitch on the day.
Thing is, I did pose the question to DAA's public affairs people, by leaving a message on their answering system. A couple of days later a real person came back to me to ask details of my query, which I provided.
They haven't responded yet. If anyone is talking to that office, tell them from me it’s OK.
